This all‑moissanite ring「AYA COLLECTION “PHOTON” 」was developed with meticulous attention to every aspect of 【デザイン・品質・技術】. We take moissanite rough stones of more than ６０ carats and shape them using the laser‑cutting techniques and handwork of skilled craftsmen, consistently handling the final cutting＆polishing in-house. To carve and polish moissanite roughs with a hardness comparable to diamonds requires both state‑of‑the‑art precision equipment and the traditional skills of experienced craftsmen working together.

Moissanite has a higher refractive index and dispersion than diamond, producing the rainbow sparkle known as “fire.” By fully leveraging moissanite’s characteristics and researching and developing Craft Meister’s cutting and polishing techniques, we have created an all‑moissanite ring that emphasizes the beauty of the piece and shines with vivid brilliance.

A sculptural beauty found only in high-quality moissanite. A pure, unsullied, solid collection of moissanite used exclusively by Radian, exquisitely shaped. Pure, unadulterated moissanite jewelry has been born.

• About the jewelry brand "RADIANN"

【Concept】
『Diamonds are humanity's dream / Moissanite is humanity's ally』
―To make jewelry a part of everyday life at prices everyone can afford.
―Manufacturers, sellers, and buyers of ethical jewelry can all take pride.
―Not just an accessory, but an essential form of happiness for everyone involved.

【Brand】
They are pioneers in the moissanite business—a brand launched before the term "moissanite" was even recognized and before ethical practices and the SDGs became widespread.

"Radian" (registered trademark at the Japan Patent Office) is derived from the gemstone cutting technique "radiant cut" and the English word "radiant," which is used to describe a smile or a state of happiness that sparkles.
