This prehnite ring is ready to ship today. One available. Size 5.25 US.
It features a genuine 8x6mm oval prehnite cabochon in soft celadon green, its smooth surface quietly translucent with a gentle inner glow, as warm copper grows directly around it in antique finish. A calming, clarifying presence for daily wear. A piece made for someone who wants something grounding and real, ready now.
Prehnite is associated with calm, renewal, and gentle clarity. Wear it when you need to feel open and steady.
Why Prehnite
Prehnite is a naturally occurring calcium aluminum silicate mineral, its soft celadon green color the result of iron content during formation. First described in the late 18th century, named after the Dutch colonel who brought it to Europe from South Africa. Long associated with calm and renewal. It is chosen for its soft green translucence, its smooth oval form, and its gentle, clarifying energy. No mystical claims. Just a beautiful stone with a meaning that fits real life.

How This Ring Was Made
Made in my small Santa Fe studio. I hand-selected this stone for its color and translucence, then encased it in copper using traditional electroforming techniques. Copper grew directly around the stone through an electrical process, forming the band organically. No molds, no mass production. This ring is one of a kind.
Care
Remove before swimming, showering, or applying lotions. Store dry. Prehnite is relatively durable — the copper is the part to protect. Let the antique patina deepen naturally with wear, or polish gently with a soft cloth to brighten.

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.
How to Measure Your Ring Size at Home
Some of the easiest methods to measure your ring size at home is by using a measuring tape or a piece of string or using a ring you already own.
✨ Option 1: Use a Ring You Already Own
- Choose a ring that fits the intended finger.
- Measure the inside diameter of the ring with a ruler (in millimeters).
- Compare the measurement to a standard ring size chart (for example: 16.5 mm = US size 6).
✨ Option 2: String or Paper Strip Method
- Cut a thin strip of paper (about 5 6 mm wide) or use a piece of string.
- Wrap it snugly (but not tightly) around the base of your finger.
- Mark where it overlaps, then measure the length in millimeters.
- Match the circumference to a ring size chart.
✨ Tips for the Best Fit
- Measure your finger at the end of the day, when it’s largest.
- Avoid measuring when your hands are very cold or hot.
- If you’re between sizes, go with the larger size for comfort.
- Wider bands can feel tighter consider sizing up 1/4 1/2 size.
If you’d like, tell me how you measured (inside of a ring you already own or the string/paper method), just send me the exact measurement in millimeters, and I’ll confirm the correct size for you. Alternatively, you can look for your ring size at www.ringsizes.co
Prefer something more accurate? I also offer plastic ring sizers in my shop - a reusable tool you can keep on hand for finding the perfect fit every time.

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, necklace, earrings, cuff, or bracelet before shipping
- Clear finish — no change to the look or feel of your piece
