With the great Tsumeb mine now history, specimens of this quality are hard to come by. These deep, emerald green dioptase crystals, to a whopping 2 cm in length on the largest, completely cover the whole specimen with glistening color. In addition, they are fairly gemmy for the species and have vibrant luster. Just a great piece! For the price range, especially, I do not think I could replace this with one of similar quality without stepping to the 4-5k price tier. NO DAMAGE to the display face. Lastly, the piece photos better horizontally but really can be stood vertically for maximal display, with the larger crystal then centered on the top half of the specimen.
