11g Dioptase Crystal Cluster from Congo spessartite It displays a similar daylight

It displays a similar daylight fluorescent characteristic (except the colors are a greyish green to deep blue green) as the Rogerley material

I would like to note that it does look like it was polished on one facet on the termination of the large crystal

Measurements: 20mm x 14

This piece was cleaved from a larger geode to show the beautiful zoning within

11g Dioptase Crystal Cluster from Congo spessartite It displays a similar daylightThis is an amazing thumbnail sized dioptase crystal cluster. This piece has a beautiful deep blueish green color and great crystal structure. The crystal terminations are fairly gemmy, too (when back lit). The color is slightly different than what the images and videos show, as the camera cant quite capture the actual color. We consider this piece to be a Thumbnail (TN) sized mineral specimen.
