instapicChiswick Auctions is offering a 10.51 carat natural Burmese ruby ring from a private European estate, in its upcoming Jewellery sale on Tuesday, 17th September, 2019.

The ruby ring is accompanied by two gemmological reports that confirm it is natural and unheated.

Commenting on the ring, which is estimated to fetch £25,000-£35,000 at auction, Sarah Duncan, Head of Jewellery at Chiswick Auctions, said: “We are delighted that two years on from the sale of our last ruby ring, (which achieved £147, 600 at auction),  we are able to offer such an extraordinary ruby of an even larger size. Natural rubies above 5 carats are very rare and one over 10 carats is exceptional. Rubies of this size infrequently come onto the market and because of this and its outstanding quality we expect interest from around the globe.”

Rubies are found throughout the world from Australia to Africa, but the most famous and prized stones come from the remote ruby mines in Mogok, Upper Burma (Myanmar). This small area, only a few square miles, is known as the “Valley of Rubies” and has produced some of the most beautiful gemstones in the world.
