Accompanied by premium report No. 74530 dated 20 may 2014 from the SSEF Swiss Gemmological Institute stating that the approximately 10.00 carat ruby is of Burma (Myanmar) origin, with no indications of heating and the colour of this ruby may also be called ‘Pigeon’s Blood Red’ In the trade; Also accompanied by an appendix stating that the ruby possesses extraordinary characteristics and merits special mention and appreciation. The ruby exhibits a saturated and vivid red colour, combined with a fine purity and a very attractive cutting style. the tiny inclusions found by microscopic inspection represent the hallmarks of rubies from the classical ruby mines in Mogok Valley in Burma (Myanmar), well known for its wealth in gems since historic times. Its saturated red colour – poetically also referred to as « Pigeon Blood Red » – Is due to a combination of well-balanced trace elements in this gemstone, characteristic for the finest rubies from Mogok. The ruby has been spared exposure to heat treatment and its clarity and colour are thus all natural. A natural ruby from Burma of this size and quality is very rare and thus can be considered a true treasure of nature.
