Superb ruby and diamond ring, Cartier
- ruby, platinum, diamond
Ruby deposits are found across the globe, in place such Afghanistan, Cambodia, East Africa, Thailand and Vietnam. All deposits have yielded fine-quality gem material, but certain locations have gained reputations as consistent producers of exceptional stones: Burmese rubies are considered preeminent. Rubies were likely first discovered in the Mogok area of Burma as far back as the Stone Age. However, local legends claim that Mogok was founded in 579 AD, and various records indicate that rubies were discovered at that time.
Burmese rubies have long been considered as the most desirable rubies in the world and the crimson glow that very fine examples possess merit the descriptive term of 'pigeon blood' for their high colour intensity. Famous for their rare combination of rich colour intensity and red UV-fluorescence, Mogok rubies also exhibit a velvety softness caused by the tiny needle inclusions which scatter light throughout the stone. Of all the locations in which rubies are found, the Mogok region is renowned for producing the distinctive intense red colours and bright red fiery brilliance, which are the benchmark by which all fine rubies are judged.
