Rare 10.51 carat natural Burmese ruby ring

Sells for more than 18 times its pre-sale estimate at auction

Chiswick Auctions saw an amazing result for a spectacular 10.51 carat natural Burmese ruby ring in our Jewellery sale last week. The ring, from a private European estate, sold for £462,500 (incl. BP), which is more than 18 times its pre-sale low estimate of £25,000. This set a new house record for Chiswick Auctions. The impressive ruby is accompanied by two gemological reports that confirmed it was natural and unheated.

Jewellery sale on 17 September

Commenting on the sale, Sarah Duncan, Head of Jewellery at Chiswick Auctions, said: “We are delighted with the result of this extraordinary ruby. Natural rubies above 5 carats are very rare and one over 10 carats is exceptional, so we knew that it might attract a lot of attention. Rubies of this size infrequently come onto the market and because of this - and its outstanding quality - bidding was extremely competitive.”

The ring sold for £462,500 (incl. BP) to an undisclosed international buyer on the telephone.

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 of only a few square miles is known as the “Valley of Rubies,” and has produced some of the most beautiful gemstones in the world.
