Description

This fine specimen is covered with very glassy and gemmy, rose-brown to tan, elongated orthorhombic crystals and is a totally different styled cabinet plate of Olmiite rather than the bowtie-like balls of many of the smaller specimens. From my personal collection, came from the  Fall 2008 find at the N’Chwaning II Mine of South Africa.
