Description

From the new find of 2017. Platy, green tangdanite on clinoatacamite crystals. The clinoatacamite is a bit stronger blueish green. It's impossible to get the color right on photos - like with dioptase the color of those minerals turns out blue, not the intense teal/petrol color you see in nature.

I tried to adjust, but it doesn't work out well enough. The material looks much better in nature.
