5.18g Dioptase Crystal Cluster from Congo

This 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). We consider this piece to be a Thumbnail (TN) sized mineral specimen.
