Couldn't load pickup availability
Soft blue-violet tanzanite, silky and shifting, set in the curve of an electroformed copper crescent. Tanzanite moves between blue and violet depending on the light and angle, and against antique copper that shift reads extraordinary, cool and warm at once, mysterious and quietly luminous. This is a ring for the ones drawn to something rare, something that changes as you move through the day. The open adjustable band fits a wide range of sizes and the stone is striking enough to wear alone.
Tanzanite is associated with transformation, intuition, and spiritual insight. It is connected to the third eye and crown chakras, linked to clarity of vision, higher awareness, and inner truth. December birthstone. Wear it when you need to feel clear, perceptive, and aligned.
Why Tanzanite
Tanzanite is a variety of the mineral zoisite found in only one place on earth — a small mining area near Mount Kilimanjaro in Tanzania. Its remarkable blue-violet color and strong pleochroism, the ability to show different colors from different angles, make it one of the most distinctive gemstones in the world. It was discovered in 1967 and introduced to the jewelry market by Tiffany and Co., who named it after its country of origin. Tanzanite is also a December birthstone alongside turquoise and zircon. No mystical claims. Just a genuinely rare and beautiful stone with a meaning that fits real life.

How This Handmade Tanzanite Moon Ring Is Made
Each tanzanite cabochon is hand-selected for its color depth and blue-violet shift before the copper crescent is built up around it through an electrolytic electroforming process. The copper grows organically around the stone and setting, creating a granular textured surface completely unique to each piece. The antique finish warms the copper and creates a striking contrast with the cool blue-violet stone.
A Note on Stone Variation
Tanzanite is a natural stone and each cabochon will vary in the balance of blue to violet and depth of color. Your ring will be similar to the one shown but entirely one of a kind.
Care
Tanzanite is relatively soft compared to other gemstones — avoid hard impacts and store carefully. Remove before swimming, bathing, or applying lotions and perfumes. Store dry.

Product Details
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

- Clear finish — no change to the look or feel of your piece
