LOOSE UNTREATED RUBY        NATURAL COLOR        Hardness 9

RETURN TO »» RUBY

Chemical properties:  corundum is composed of pure alumina; its colouring is due to metallic

oxide traces or inclusions. The color of RUBY, due to chromium oxide, gives its best 
effect under electric lighting.
Gems are generally found in alluvium, but come either from basaltic slags, or from metamorphized marble.
