Premium Material
Materials
We make everything for longevity, not just beauty. The core is cast from Solid S925 Sterling Silver, ensuring a heavy, substantial feel.
The Finish: Depending on your selection, the piece is armored in either Rhodium (a rare member of the Platinum family) for a mirror-like silver finish, or 18K Gold Vermeil for a deep, rich gold tone. Both finishes are chemically bonded to resist tarnish, sweat, and daily wear.
The Stone: 100% Natural Opal — formed over 100 million years as silica-rich water crystallized into microscopic sphere structures deep within the earth. Light diffracts through these natural spheres to create a mesmerizing play-of-color that shifts with your every movement. No two stones are identical. At 5.5–6.5 on the Mohs hardness scale, opal is beautifully wearable with mindful care — simply remove before showering or strenuous activity.
The Opal Collection
Most gemstone jewelry is mass-produced with synthetic stones, glass "opalite," or undisclosed treatments cut for speed, not beauty. We reject that model.
Our Natural Opal collection focuses purely on what makes this stone extraordinary — the mesmerizing play-of-color created by light diffracting through microscopic silica spheres formed deep in the earth over 100 million years. Every flash of iridescent fire is a unique optical fingerprint that cannot be replicated in a lab.
You receive a genuine, one-of-a-kind gemstone with the depth and character of a collector's specimen — without the inflated gallery markup. It is the intelligent choice for the woman who values authenticity over mass production.
Size & Fit
Chains & Necklaces
Available in 18", 20", 22", and 24" lengths. Measure an existing chain you wear comfortably — or wrap a soft tape measure around your neck and add 2-4" depending on where you want it to sit. 18" sits at the collarbone. 22-24" falls mid-chest.
Bracelets
Available from 7.5" to 9". Measure your wrist just below the wrist bone. Add 0.5-1" for a comfortable fit. Most men wear 8" or 8.5".
Rings
US sizes 6-12, including half sizes. True to standard US sizing. If you know your size, it will match. If you don't, measure the inside diameter of a ring that fits — or wrap a strip of paper around your finger and measure the length in millimeters. Size guides are available at checkout.
Adjustable Rings
Some designs feature an open band. These can be adjusted for fit — but Swiss Watchmaker Steel holds its shape. Adjust once and leave it. Not designed for repeated bending.
Built to Stack
Every chain, bracelet, and ring is engineered to work together. Widths, finishes, and proportions are designed as a system. Start with one. Build over time.
Find Your Ring Size
Finding Your Ring Size.
- Cut a strip of paper or a piece of string. Wrap the paper or string around the finger to be sized.
- Slide the paper or string up to the knuckle, as the ring must be sized large enough to able to slip off and on, over the knuckle.
- Mark the intersection point of string. Make sure to mark both points of the string.
- Place the paper or string next to a ruler and write down your measurement.
- Locate your ring size by locating your measurement on the size chart.
If the measurement falls in between two sizes, it is recommended that you choose the larger size. Your fingers might also swell if you're pregnant or taking certain medications. Take this into account when measuring your fingers
Finding the Ring Size for Your Loved Ones.
- Find a ring that your loved one currently wears.
- Make sure he or she wears that ring on the finger you are shopping for.
- Using a ruler to measure the inside diameter or inside circumference of the ring.
- Match your measurement with our size chart to find your perfect fitting size!
If the measurement falls in between two sizes, it is recommended that you choose the larger size.

The Stellara Opal Necklace
Frequently Asked Questions
Every stone in this collection is 100% natural, untreated opal — formed over 100 million years as silica-rich water seeped into rock cavities and solidified into microscopic sphere structures. No synthetics, no glass "opalite," and no lab-created substitutes.
The mesmerizing play-of-color you see is pure physics — light diffracting through those natural silica spheres — and it is impossible to replicate exactly. Your specific stone exists nowhere else on Earth.
Natural opal ranks 5.5–6.5 on the Mohs hardness scale — beautiful and wearable, but it asks for a little mindfulness. We design 68% of this collection as pendants and earrings specifically because these formats naturally protect the stone from impact.
Simply remove your piece before showering, swimming, or strenuous activity. Treat it as an intentional ritual — put it on with purpose, take it off with care — and it will reward you with a lifetime of unique fire.
No — and that is what makes it special. Because every natural opal contains a unique arrangement of silica spheres, the play-of-color in your stone will shift differently depending on the lighting. Sunlight, office light, and candlelight each reveal something new.
We hand-select every gemstone for color vibrancy and fire, so while the exact pattern will be yours alone, the quality never varies. Think of it as receiving a one-of-a-kind geological fingerprint.
Three reasons. We craft exclusively in solid S925 sterling silver instead of 18K gold, keeping the focus on the gemstone. We source directly, eliminating retail middlemen. And we skip expensive third-party paper certifications — instead, every piece includes our own Awareness Avenue Certificate of Origin.
You pay for the earth-mined stone and the premium silver setting. Nothing else.
Never. "Green skin" is caused by copper or nickel reacting with sweat — we do not use base metals. Every piece is crafted from solid S925 sterling silver, which is hypoallergenic, nickel-free, and lead-free.
S925 silver may develop a natural patina over time, which many wearers love. If you prefer a bright finish, a quick wipe with a polishing cloth restores the original shine in seconds.
Yes. Every order ships in our signature premium packaging with an Awareness Avenue Certificate of Origin and a dedicated Opal Care Card — ready to gift or to unwrap as a well-deserved treat for yourself.
As the October birthstone and a timeless symbol of hope and creativity, natural opal makes a meaningful gift for birthdays, anniversaries, or any milestone worth remembering.
