Calcite Crystals and Oyelite SKMF 013

Sprays of pinkish-white oyelite on glassy clear calcite crystals with multi-terminations

Measurements:  46 x 27 x 23 mm

Description:   Small balls consisting of pinkish-white sprays of minute oyelite crystals sit on two calcite crystals, with numerous terminations. The largest edge is 20 mm and some terminations are glassy clear. Due to the delicacy of the oyelite sprays, it has quite a bit of damage, but the calcite appears undamaged.  A very nice specimen!
