Colemanite (Ref: SV221)

Boron, Kern Co., California, USA
80mm x 55mm x 40mm
minID: 4A8-8XC
$600
Stark white starburst formation of Colemanite on a sparkling, cream-colored Calcite matrix. The Colemanite cluster is 4cm in size and perfect. So many Colemanite specimens are 'boring' dense clusters of similar sized crystals - this well isolated starburst really stands out and is exceptional.
Data last checked on 22nd Apr 2025 - specimen may no longer be available
