Description: This rough chrysocolla has a beautiful blue and green color. its as vibrant as you could imagine, but its not very stable for cutting. Rather than being agatized, it is more opalized and brittle, so it has lots of cracks. it is fantastic for cutting small cabochons, but I'm talking stacker ring size cabochons. as a rough rock to display, its perfectly fine and full of color.
Chemical Composition: CuSiO3·2H2O
Grade: Semi Precious
Inclusions: Not so many inclusions, there are druzy pockets with mini quartz crystals on some, the main issue for cutting is the cracks.
