Description

The specimen has a short chain-like sequence of globular formations of olmiite. The olmiite has basic radial clusters of close to gemmy lustrous brown crystals interconnected in a sequence. Then there is a deposit of calcite which is lustrous and gemmy and translucent light grey. The calcite crystals have a complex habit and are largely interconnected. The largest olmiite is 1.1cm across. The calcite has some minor abrasions.
