My name is Siyu and during my final semester of school, while interning at Jewel Envy we needed to stay home due to COVID 19. For our final project we were required to make something at home with limited simple materials. I choose to reuse some paper to make a paper flower necklace. The process was not hard and the results were amazing!
Cut four of the same size square papers and fold three times to be the shape showed in the images.
Cut an angle on every paper to let them all be flower shape.
Then cut different parts off to be petals.
Use glue to glue every petal together.
Use a tool to roll up every petals’ edges.
Cut the end of every petal then glue them together.
A paper flower is done.
use a tool to roll up a long narrow paper
Glue the paper rolls to the back center of every flower. A commercial chain or lace ribbon can go though it to hang the flower
Another way to hang the necklace is to cut two narrow symmetrical slits to let a lace ribbon go through every flower.
Yuko is a Japanese artist based in Melbourne, Australia. She initially studied Japanese Literature in Tokyo, but moved to Australia in 2001 to study Jewellery Design. Her work has been exhibited in Europe, Japan, New Zealand and Australia.
“The jewellery I create is much like words and images, but concealed in shapes that are borrowed from nature. I utilise elements such as shape, colour, texture and movement, and transform them into wearable objects that I hope closely engages the wearer or viewer of the piece, triggering an emotional response and inspiration.”
Yuko’s pieces are realised through a spontaneous reaction to her materials, which creates outcomes that are never the same, reclaiming found objects as wearable sculptures. She is interested in making contemporary jewellery that interacts with the wearer. Yuko gives free reign to the interplay between the fundamental qualities of material, texture, shape and colour. Each piece is a tribute to her very personal and charming way of observing the world.
Spoon handles are cut into small faceted beads, like crystals, and painted in botanical greens and reds. Sometimes Fujita leaves her wooden carvings raw, at other times she lightly burns them. The effect is of secret gardens and lost worlds full of seeds, plants and animals, all living in harmony.
She explores the universal void; the feelings of longing and yearning in us all and manages to delicately evoke this in her work, which is often as tactile as it is visually compelling.
“Jewellery is complete when it interacts with the wearer emotionally and physically.”
“I admire the beauty in nature. Particularly the botanical world where I like to extract elements such as shape, colour, and texture to create a new identity. By also borrowing from my Japanese literary influences, I use visual language to tell a story through obscure metaphorical forms, so that the wearer can engage with my work using their own interpretation.”
I find these blogs just keep getting longer and longer as I add more and more information each month. But, that’s what I love about this, being able to share what I know from the world of gemmology.
July, a hot month for a burning hot stone, figuratively of course. Ruby is known to be the traditional birthstone for July and is the vivid, glowing red variety of the mineral corundum. Rubies are an ancient stone and carry many meanings attached to them, but generally are associated with the sun and blood, thus they symbolize nobility, purity, passion and life. Rubies have a long history, with mentions from the bible and from ancient India. They are especially revered in South-East Asia and India and used to adorn all forms of ornaments and clothes of the royalty of the area. While today there are many locations where rubies have been found and mined, Burma now Myanmar, has been the source of the most desired rubies from as far back as 600CE. It was here the optimal colour, pigeon blood red, was sourced. In days past, a perfect ruby was the colour of fresh pigeon blood on white sheets, morbid but also kind heavy-metal, no? These prized stones hail from the Mogok area of Myanmar (Burma) and while Mozambique and Sri Lanka are also hosts of beautiful rubies, the Burmese name will cost you more. Think of it as buying a brand name for shoes or clothes over no-name, Burmese rubies are like the Gucci, Dior and Prada of rubies.
Ruby is identified as:
1) Trigonal Crystal System, not to be confused with crystal habit. (Note, habit is how the mineral crystallizes)
2) Oxide Composition,
3) Simple Oxide Family
4) Mineral = Corundum – Al2O3
5) Variety = Ruby.
Like beryl, corundum is naturally colourless, and thus colour comes from impurities within the stone. Ruby is the red-crimson variety, sapphire is the blue variety and padparadscha is the pink/orange variety. All other colours are classified as “fancy sapphire”, this is odd as the beryl varieties had unique names but when it comes to corundum in the yellow, violet or green hues then they are referred to as a “yellow sapphire”, “green sapphire”and “violet sapphire”. Confusing, I know, even to a gemmologist. Unless a colour is in front of the word “sapphire” then it is assumed one is referring to the blue variety of corundum.
Now for the fun part, how is ruby so red? Ruby, (derived from ruber; Latin for “red”, big surprise there) gets its colour from traces of chromium, within the crystal structure. Remember our blog from May and June, chromium is a very colouful element. Green in emeralds and colour change in alexandrite. This element does more than just give you a shine on your wheels. As started before this colour all comes down to how light interacts with chromium ions, chromium(III) to be specific, within the crystal lattice. Without getting too technical, when chromium is in corundum it will replace an aluminum ion and the distortion causes the chromium electrons to absorb the ultraviolet, violet, and yellow-green regions of the spectrum. If one percent of the aluminum ions are replaced by chromium in ruby, the yellow-green absorption results in a red color for the gem. With emeralds, the chromium absorbs more of the violet and yellow-red wavelengths of visible light, thus we see green.
Now, let’s get serious about rubies. With the high price of rubies, some exceeding far beyond the cost of diamonds even, there are many treatments, synthetics and imitations to watch out for when hunting for rubies. First, some terminology needs to be explained, mainly the terms “natural”, “synthetic”, “imitation” and “treatment”. A natural gemstone refers to a stone made from the earth and is what most people desire/expect. A synthetic gemstone is an identical copy of a natural, just made by man. This means it has the same chemical formula and crystal structure as its natural counterpart. Ideally, the term “synthetic” should only be used if the man-made stone has a natural counterpart. If there is no counterpart, then this stone is referred to as an “imitation”. An imitation is a stone or material representing another stone. Imitations can be natural or synthetic and confuse many people. Cubic zirconia is one of the most common samples for imitating precious stones. Treatment or a treated stone is a natural stone that has been tampered by humans to improve colour saturation, clarity, and durability. There are many interesting ways we have discovered to help improve the natural beauty of precious stones.
For rubies, the most common treatment you will see is heating and assembled rubies. Heat treatment is as the name suggests. The rubies are slowly heated up to a temperature of 1800 °C. The heat helps eliminate inclusions and can enhance the colour of the stone. An assembled ruby is actually ruby grains assembled with leaded glass and coloured with a variety of elements, like copper, boron, sodium, calcium or potassium. This is a 4 step process and commonly used to fill fractures within the ruby. Oiling is another treatment used on rubies but not as common as with emeralds. The stone is placed in heated oil in a vacuum chamber and the oil is then drawn into the cracks of the stone or it is ground while the stone is being cut. All of the treatments are used to help increase the clarity and colour of the ruby as a clear and vibrate stone is the most desired.
Now for the best part, how can one tell if their ruby was treated, synthetic, imitation or a natural red wonder? Well the most obvious answer is get a professional to look at it. Second, like with all gemstones look at the cost. If the price is too good to be true then it probably is. Sometimes traders don’t know their material and this can work in your favour or against you, buyer beware. If you have a loupe or a strong magnifying glass there are a few things you can look for in your ruby. For the assembled or glass filled rubies the difference in lustre between the glass and the ruby can help in identification. With a loupe, looking at the light reflected off of your ruby, examine for cracks and fractures, if you see a difference in lustre, or shine, the duller material is the glass and the brighter material is your ruby. You may also see bubbles in your filled fractures from the glass.
For heat treatments you need a microscope but if you happen to see inclusions in your ruby, especially other minerals look at the crystal surrounding the inclusion. If you see cracks or minor fractures radiating out from an inclusion, like a lily pad, that is possible evidence of heat treatment. The heat caused the inclusion to expand and contract at a different rate compared to the rest of the ruby, thus stressing the ruby and causing it to crack. You may also see “healed” fractures but alas you will need a professional eye to show you what I’m referring too. Oiling is fairly easy to identify as your hand/fingers may become red after handling the stone. You will also notice with your loupe that the colour of the stone is concentrated along fractures within the crystal.
Now what about natural vs synthetic rubies. A flawless gem is the most prized gem but also one of the most difficult to identify as inclusions help greatly. When it comes to synthetic stones, you’ll need a microscope to discern the origin of your ruby. All gemstones leave clues as to how they formed within the crystal structure and carry trace element signatures. While the chemical signature is the best way to identify a stone’s origin you have to destroy a piece of your stone. I don’t think many people would be interested in having a hole in their $30,000 ruby to see if it’s natural or synthetic. Thus by using high powered microscopes and polarized light, gemmologists can see signatures as to how gemstones crystallized and your stone is left untouched. Synthetic rubies are produced either through the flux-melt method or flame fusion method. These methods should be disclosed when selling synthetic/lab-created rubies and if not, ask. Since I will be talking about sapphires in September, I will focus on the flame-fusion process here and the flux-melt there.
The most common synthetic ruby is the flame-fusion ruby, a process improved upon by the french chemist Auguste Victor Louis Verneuil to start producing synthetic ruby and sapphire in mass quantities. In a nutshell, the stone is grown like a stalactite, from the base up. Aluminum oxide (corundum) powder and chromium oxide (red colour) are mixed together and then sprinkled at a controlled rate through an oxyhydrogen flame and heated to 2200℃. The now liquid droplets of ruby then fall onto a seed crystal and the ruby begins to grow. The end result is a ruby or sapphire boule. The reason this process is so popular is because the crystals grow at an alarming rate. A typical 40 by 80mm boule weighing 250-500 carats would take 4 hours to create. This process works for creating synthetic spinel as well. Little fun fact here, while you can create ANY colour of sapphire, chemists are still unable to create an emerald green sapphire. Today the yearly, world production of flame fusion corundum due to Verneuil work totals over 1 billion carats, most used in watches, lenses and manufacturing.
The rubies created by the flame-fusion process are grown, layer by layer. These layers are actually curved called “curved striae” and a distinguishing feature of the ruby as each layer is built upon the last layer and oozing over it, like a tower of pancakes. Now a hard fact here. Nothing in natural minerals is curved when you’re referring to the growth of a mineral (fractures are the exception but that’s for another time). Now these curves are usually only visible with a microscope unless it was a rushed crystal. Other features would be inclusions of bubbles or unmelted powder sprinkled within the ruby.
Another way to tell these synthetics from naturals is if you look through the table of your stone with a dichroscope or using a polarized lens/glasses. If you see your stone strongly change colours as you rotate it with light from behind, you may have a synthetic. Reason for this is because of the structure of the boule. While ruby and sapphires are hard, they can be brittle, and when you’re grown in an unnatural way, you’re going to be unnaturally brittle. To prevent this, split the boule down the middle once it’s done crystallizing. This releases the tension built up in the curves layers. The changing colour comes from a property all crystals have, well all but the cubic crystal system (they’re special), called pleochroism. In short this means the atomic structure of crystals can split light into two waves, the short and long wave, due to the duality nature of light as an elector-magnetic wave/particle. In turn you will see some stones change colour depending on the angle of the stone to your eye. Ruby, being a trigonal stone, has this property and when viewed from the side as opposed to down the “optic axis” (the angle at which both light rays are at the same speed and thus don’t split). I know there’s a lot here but add this all up together knowing the fact that the boules grow along the optic axis as well. Thus when you split the boule, your largest surface is now the split side. Gem cutters then use this side as the table face to save carats. This face is perpendicular to the optic axis thus pleochroism is as its highest value, ot more noticeable. SCIENCE AND LIGHT!!!
Now if you want to search for your own ruby, just like all the other precious stones out there, it is a buyer beware world out there. Ask questions, and use your gut first. Also look at the name. Many stones have the name “ruby” in them in order to make you think they are related. The infamous Balas Ruby in the Royal British Crown is actually a red spinel. Rubellite is a pink/red variety of the tourmaline family. Again if it’s synthetic, the process should be indicated with the purchase. Imitation stones will be easier to spot as they will not be as hard or will not show the pleochroism.
What about star rubies? Yes they exist naturally and are the result of thin mineral hairs of rutile crystallizes alongside the triangular habit/system of the mineral. When these hairs are cut into a dome or cabochon shape along with the rest of the ruby, the hairs will reflect light like a spool of thread. With three spools comes three reflections thus we see a star. This is a phenomenon known as asterism, and if there is only one reflection like a slit, it’s known as chatoyancy, or ‘cat’s eye’.
While these are just some quick pointers for general interest if you are interested in more information I suggest some of the links and books below.
GIA encyclopedia page for rubies. Very friendly for just starting to understand gemstones with links to countless articles about ruby mines, unique specimens, ruby history, lore and more.
Gemmology by Peter read – A gemmologist bible, make sure to look for the latest addition as there is always new information to be added to textbooks. This book covers ALL the gemstones as well as how to use the tools to identify naturals, synthetics and imitations. Warning this book is very technical.
Jewels: a secret history by Victoria Finlay – an excellent read into the history and lore behind some of the more renowned gemstones.
Well that was a novel and a half, I hope you enjoyed this blog about the July stone, Ruby. In August I will be informing you about Peridot, the olive-lime green gemstone of the deep earth.
I have struggled with not being creatively driven when I had all the time in the world to create while staying at home to try and flatten the curve. I had hoped that I would use my “extra time” to create voraciously to prep for an Art Fair, but in all honesty I barely added the finishing details to pieces I had already photographed in the lead up of participating in this year’s Toronto Outdoor Art Fair – this year the Toronto Online Art Fair from July 2nd-12th. The online sale continue until December of this year, check out my artist gallery here.
My current work is shaped by my experience with my family’s foundry business which produces cast iron. A focus of this material has led to years of sketching ironwork producing distinct repeating shapes and patterns. Each piece starts as separate components and comes together with a purposeful awareness of composition and how the piece will be worn.
This past weekend I started to get back into the groove of creating more pieces using my ironwork patterns. Keep your eyes peeled for updates!
Hey everyone, this is Roozbeh Rastegar, a new member of Jewel Envy. I am a recent graduate from Jewellery Art Program at George Brown College and glad to join to the Jewel Envy professional team where I can design and create.
These are some samples of the pieces that I made to familiarize you with my taste of design and style of fabrication.
I don’t know if you saw this necklace, I made it last year to put forward for an exhibition. I like to challenge myself to make something more elaborte than I usually do (I tend to favour sleeker elements and not too complex elements) at least once a year, and last year it was this one:
Oxidised sterling silver and 10kt yellow gold, two-tone blue needled felt, blue topaz and sapphire
I love the colours, and the movement it makes, so I was excited (and a bit sad) to sell it at Christmas. So, I decided to make another one (still one of a kind, though!). This necklace combines a number of different elements. As I’ve talked about previously, the elements I currently am using in my work are inspired by the shape and form of the immune system. For me, the sticks and rings are representational of blood vessels that red blood cells as well as cells of the immune system move around in. The small round roller-printed hollowforms are inspired by lymphocytes and the hollowforms with the needled felt are inspired by macrophages. Like alot of systems, the immune system is there to protect the body, but it can also be turned against the body, so this is the darker side.
When I decided I wanted to make another version, I decided this one should the the “light” version. I finished it awhile ago, of course, now the challenge is to try and take good representational photos. These aren’t the final pics, but some rough ones on their way to the being more professional:
This one has a white matte finish, and I decided on an orange/red colour theme with orange sapphire and deep red rubies
Here’s a bit of a closer look at the central elements, I think I still need to work on bringing out the texture on the hollowforms a bit more-what do you think?
The other challenge is to try and convey a sense of scale, since it’s difficult to tell how large/small the piece is without some kind of frame of reference, so I thought I’d try being my own model — I’m not sure I recommend this, it was the world’s biggest hassle trying to get some good, in-focus pictures. So far this was the best I could do:
It’s not bad, you can tell how big it is, but I think I need to find another model!!
I did manage to take this portrait that I was pretty pleased with, I think I might be using it some more in the future!
Anyway, fancy a nice piece of statement jewellery yourself? Come in and browse the studio, or talk to one of our goldsmiths about making that piece of jewellery you’ve been thinking about a reality!

This is another blog post by Siyu Hu our George Brown College 2020 intern, and now graduate!
During the third-year study at George Brown College while interning at Jewel Envy I made a necklace. The inspiration is from a combination of natural beauty from terrace fields and my interpretation of them. All the elements including the clasp, the chain, and the shapes of the main pieces are inspired by terrace fields.
Rhino is a 3D product design software which is widely used by jewellers. It can show your design in different ways such as technique drawing view, pen drawing view and the rendering view. I used Rhino to create a digital necklace design and chose green to be the base colour for every elements since it is the colour of the farmer plants I was inspired by.
Once the design is drawn in Rhino it is printed in 3D and then each piece is cast in sterling silver separately. Then the pieces are finished and I used enamel to create the natural lanscapes colour.
“As a jeweler I’m interested in the animation, the living legacy of objects. When my pieces are worn, they’re activated – that is, their story and felt sense of meaning are brought to life.”
Artisan and educator Sewit Sium has been crafting historically referenced jewelry for over a decade. She is driven by the idea that adornment is not solely a marker of trend or wealth, but also a valuable educational tool, reflective of history, culture, tradition, and indigenous technologies. In many instances, what we choose to wear and how we choose to wear it reflects our ancestral memory, relations, and ongoing story as people.
Sewit Sium jewelry was born to uphold this idea that fashion is language and a powerful form of storytelling. Each hand crafted piece takes us on a journey through history, while embodying a story that is relevant to our lives today. The line includes powerful amulets and talismans that anchor us in the present moment, only to say “Im here but my history walks with me.”
With an emphasis on visual political statement, Sewit’s mission is to reconnect cultural image and iconography with original context. She draws from a rich diversity of African iconographies and artistic movements from both the continent and its diaspora; each offering unique insights and stories of the world and our place within it. Therefore all designs seek to beautifully honor and celebrate the original peoples that lay claim to them.
“I’ve always been captivated by the intersection of jewelry, education, and grassroots activism. Prior to starting my business, I taught Fashion Politics and Design at various High Schools in NYC, using jewelry as an educational tool, as primary source material (like a text) to teach predominantly Black and Brown youth about their history, about the world. We had powerful conversations about where we came from, where we are now and where we are going.”
“We literally know about the world because of what was engraved and memorialized in jewelry and stone. Jewelry is the oldest form of decorative arts, a phenomenon that was born on the African continent. Without it, we wouldn’t know about ourselves. This is why I’m continuing the legacy of hand-making statement jewelry encoded with this history, culture, sentiment, and love. My hope is that people adorn and become activated and inspired by my work.”
Axum Gold Coin Ring
A large part of what we know of the Ancient Kingdom of Axum, aka Aksum (modern day Eritrea and northern Ethiopia) is engraved in gold and intricate and opulent jewelry. This ancestral knowledge is literally imbued in Axum Gold Coin Ring – in the minting and movement of indigenous currency, which has since been found as far as India.
Coral Scarab Amulet Ring
The Scarab, a beetle indigenous to Egypt, signifies life, rebirth and regeneration. The ancient god Khepri, Ra as the rising sun, was often portrayed as a scarab beetle or as a scarab beetle-headed man. Khepri renewed the sun every day before rolling it above the horizon, then carried it through the other world after sunset, only to renew it, again, the next day.
