Prehnite Spire
Prehnite forms in ancient volcanic rock where heat and mineral-rich water slowly create its soft, translucent green body. Each stone is hand-selected for clarity and tone, then cut to reveal a smooth, diffused glow. A 7–9 K cool-white LED (~6–9 lumens) travels through the crystal, enhancing its calm luminosity. Prehnite is known for peace and awareness, and the cool light reflects its serene, restorative nature. This necklace will invite good energy into your life — people will ask about it, and the most curious souls are often the most genuine.

Design
Designed 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, found in the square‑shaped Spires, a precision‑drilled side‑glow fiber optic spreads light evenly through the crystal — revealing hidden depth and natural texture within each piece.
100% natural high grade crystals
Up to 250hr of continuous light

Frequently Asked Questions
It fades very gradually — not all at once. Left on nonstop, it stays visible indoors for about 3–5 days, and in the dark for around 7–10+ days. Used sparingly (for example, just at night), a single battery set can last months.
Twist the top to turn your Spire on or off. Inside is a tuned LED and an inline resistor that creates a soft, balanced glow spreading through the crystal. It’s powered by two SR626 (377) button batteries, which are easily replaceable. Each set provides around 250 hrs of continuous glow, and we include two extra sets in the box — totaling about 1,000 hrs of continuous illumination or months if used sparingly.
Each battery set typically provides ~250 hrs of continuous glow time (or months of use when turned on occasionally). The light was designed for a soft, ambient glow—visible indoors or in shade and comfortably bright at night without being distracting.
Yes. It uses two SR626 (377) button batteries in a compact pack. We include 2 extra packs in the box, covering a total of ~750 hrs.
Every Spire is made with genuine, natural crystal — not glass or resin. Each piece is hand‑selected for clarity, pattern, and how it interacts with light.
Water and splash resistant, but not fully waterproof. Remove before swimming or showering.
Yes — you can wear your Spire both on and off. To turn it off, gently untwist the top until the light fades, making sure it remains snug enough that it won’t loosen or detach from the threads. Always check that it’s secure before wearing.
The LED is tuned to around 6–9 lumens, designed to emit a soft glow visible indoors, in shade, or at night. It’s bright enough to highlight the crystal’s texture but not harsh or distracting in dark environments. Continuous use provides over 250 hrs of illumination, or months if used sparingly.
Approximately 1.5" tall and 0.4" wide (including shell + crystal). Lightweight for everyday wear.
Every crystal is unique. Expect natural variation in color, inclusions, and how light diffuses—your piece will be one‑of‑a‑kind while matching the product images.
We source our crystals from trusted partners at major deposits around the world — such as amethyst from Brazil and fluorite from Madagascar. Each piece is hand‑selected and cut for clarity, then polished and tested with light before final assembly in our Florida workshop.
