Description

Terrific deep green conichalcite spherules (under magnification can be seen rosettes of lustrous, translucent crystals) making a wonderful contrast with the light yellowish-green matrix. 

There are a couple of dioptase crystals (the biggest to 5mm) and some Apatite-CaF grothws as beautiful "flowers".

Amazing under the scope!
