Kunzite

Kunzite is the pink-to-violet variety of spodumene, colored by manganese and named in 1902 for George Frederick Kunz — Tiffany’s legendary gemologist, who first described it. It grows in big crystals, so kunzite is almost always seen in generous sizes, with a luminous, slightly glowing lilac-pink that feels modern and romantic at once.

Two things define how kunzite behaves. First, it is strongly pleochroic — it shows different color intensity down different crystal axes, so cutters orient it to face up with the best pink. Second, it has perfect cleavage and is sensitive to knocks, which (with its Mohs ~6.5–7) makes it a stone for thoughtful settings rather than rough wear.

Color

Treatments & light sensitivity

Some kunzite is irradiated and/or heated to deepen the pink. The important caveat — treated or not — is that kunzite’s color can fade with prolonged exposure to strong sunlight or UV. It earned the nickname “the evening stone” for a reason: it looks its best, and keeps its color longest, away from harsh daylight.

Daily wear

Best in earrings, pendants, and occasion rings. If set in a ring for regular wear, choose a protective mounting (kunzite’s cleavage dislikes sharp blows), store it away from direct sun, and clean it gently — warm soapy water, never ultrasonic or steam.
