Unusual specimen from a new find of beautiful Calcite with Natrolite needles from Sipi caves, Uganda. The Natrolite forms spiky colorless crystals. They are very delicate, translucent, with fine shimmering and pearly luster. Above grow richly colored amber-brown to colorless Calcite crystals. They are very well shaped, highly lustrous and gemmy. In very good condition – some small nicks.

Charming!
