This oval black onyx ring features a genuine oval black onyx in deep, absorbing black, its smooth polished surface bold and quietly powerful, as warm copper grows directly around it. A grounding, protective presence for daily wear or moments when you need to feel anchored and clear. A statement ring that wears with real weight — substantial, earthy, and entirely its own.
Black onyx is associated with grounding, protection, and steady resilience. A root chakra stone. Wear it when you need to feel anchored and strong.
Why Black Onyx
Black onyx is a naturally occurring variety of chalcedony — a microcrystalline quartz — its deep black color the result of carbon and iron oxide inclusions. Long associated with grounding and protection, and with the root chakra (Muladhara). Used across cultures for thousands of years as a protective talisman and grounding stone. It is chosen for its deep black depth, its smooth oval form, and its anchoring, stabilizing energy. No mystical claims. Just a beautiful stone with a meaning that fits real life.

How This Handmade Onyx Ring Is Made
Each oval black onyx ring is made to order in my small Santa Fe studio. I hand-select every stone for its depth and polish, then encase it in copper using traditional electroforming techniques. Copper grows directly around the stone through an electrical process, forming the band organically. No mass production, no shortcuts. Every handmade ring from this studio is one of a kind.

About Electroforming
Electroforming is an ancient technique reimagined for modern jewelry.
Copper molecules bond to each stone over several hours, creating organic textures and secure settings. Learn more about our process.
Each ring is electroformed in pure copper, a process that uses electricity to slowly grow metal over organic forms, stone, or wax-carved bases.
This ancient-meets-modern technique creates natural textures and one-of-a-kind variations — no two pieces will ever be the same.
All rings are nickel-free, can be sealed for daily wear, and finished by hand in our Santa Fe studio.
For centuries, copper has been worn as a grounding element — believed to balance energy, support circulation, and keep the wearer anchored in presence. It reminds us of our connection to the earth and our ability to return to stillness.

Care & Patina
Electroformed copper develops a natural patina over time — deepening into warm, earthy tones that tell the story of your wear.
To maintain brightness, polish gently with a soft cloth or a touch of lemon and salt.
To preserve the aged finish, simply wipe clean and store in a dry place.
Avoid wearing your jewelry while swimming, showering, or applying lotions, as moisture may alter the patina over time.
Copper Protection
Embrace the Patina
Some collectors love the rich, aged look that copper develops over time. This natural patina tells a story—of adventures taken, energies absorbed, and the passage of time. If you resonate with that earthy, vintage look, feel free to let your copper evolve organically.
Why add lacquer?
- Slows the natural darkening (patina) of copper
- Minimizes the chance of skin reactions
- Keeps copper looking brighter for longer
- Protects while preserving the earthy character of your jewelry
Details:
- Optional upgrade available for $5
- Applied directly to your copper ring, cuff, or bracelet before shipping
- Clear finish — no change to the look or feel of your piece
