Ruby Oval Shape Ring
Size 6
925-Sterling Silver
A red, gem variety of corundum. The red color is caused by minor amounts of trivalent Cr replacing Al in the crystal structure.
In traditional gemological terms, ruby has to be blood-red and of clear, face table quality to justify the name, however in wider usage any corundum with a red or reddish color has attracted the name 'ruby', and this name is usually applied in this way by mineral collectors
