Description

Sample of hexagonal euhedral prismatic crystals of Zincite crystals that are light green in colour and have an adamantine lustre. Likely a synthetic crystal. Largest Zincite crystal size: 2.8 cm x 0.6 cm x 0.6 cm. Zincite ((Zn,Mn)O) can be a deep red, orange, yellow, brown or green (rare,usually synthetic) in colour. Lustre is adamantine and streak is orange-yellow in colour. Hardness is 4 and cleavage is perfect in one direction and can have basal parting.
