Design
Design by RFH.
Spire was born from countless experiments with light — exploring how color, warmth, and wavelength interact with natural stone. Every detail was shaped to balance precision and emotion, turning raw stone into something living. The result is a pendant that reveals a fragment of time and space.
Shell. Machined from 303 stainless steel and hand‑polished for strength and simplicity. Compact, water‑resistant, and built to protect the light within.
Crystal. No two are alike. Each crystal is hand‑selected for its clarity, inclusions, and the way it comes alive under light — revealing patterns that exist in no other piece.
LED. A tuned low‑power LED (~6–9 lumens) paired with an inline resistor creates a soft, balanced glow. Designed for over 250 hours per battery cycle and 100,000+ total hours of life.
Fiber Optic. In opaque stones, a precision‑drilled side‑glow fiber optic spreads light evenly through the crystal — revealing hidden depth and natural texture within each piece. (Patent pending)

Yes. It looks like a crystal necklace when the light is off. Twist it on when you want the glow, and twist it off when you want to save battery.
The light is soft and gentle, around 6-9 lumens. It is bright enough to show the color and patterns inside the crystal. It looks best indoors, in shade, or at night.
The pendant is about 1.5" tall and 0.4" wide. It is light enough for everyday wear, and it comes with a 22" stainless steel chain.
Your crystal will match the product photos, but the exact color and patterns will be its own. That is what makes each one special. You also have 30 days to return or exchange it.
We work with trusted crystal partners around the world. Each stone is checked with light, then cut, polished, and set into the pendant. Learn more about our crystals.
