Ask a question

A quality large ruby from Burma sits between two accent diamonds in this vintage white gold ring. 

The ruby is from the Mong Hsu region, a noted source of good stones. This area was opened for mining in about 1992. 

The mount is made of 18-carat white gold,  has a fine claw setting, and sits low on the finger. 

It’s chromium that gives rubies their wonderful red hue. But the presence of this element can also cause structural faults that mar their appearance. 

This means that, unlike sapphires – another variety of the corundum mineral family – rubies of this size and quality are difficult to find.
