This relatively large specimen hosting a wide opened vug which is richly lined with numerous finest Dioptase crystals. Definitely a WHOPPER piece of sparkling green Dioptase crystals! Though the crystals are not particularly large, they measure up to up to nearly 1 and a half centimeter and are NOT just a "druse" by any standard! What´s more, the colour is a superb bright green (much better in person - Dioptase is notoriously hard to shoot - these crystals have the best colour and are actually quite gemmy!). There is very little bruising, most of it at the periphery. Quite a showpiece in person - much more impressive than the photos which are small anyhow.
