Untreated Blue Sapphire (Mogôk) Untreated Blue Sapphire (Mogôk)  Ref: 1046320
Unheated sapphires are extremely rare and the exception rather than the rule.

The Mogôk valley in Upper Burma is the source of some of the world's finest blue sapphires. Mogôk blue sapphires often come in a rich velvety blue colour and require no treatment to enhance their colour. These stones are highly sought after by connoisseurs & collectors and are in great demand by the world's top Jewellers.

Upon request, we can supply a lab report from the The Gem & Pearl Laboratory Ltd. (or a lab of your choice), to accompany this sapphire.
