Superb and 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 Calcite crystals. They are very well shaped, highly lustrous and gemmy. In excellent condition – some minor nicks.

Outstanding!
