Report no. 91506 dated 9 March 2016 from the SSEF Swiss Gemmological Institute stating that the rubies are of Burma (Myanmar) origin, with no indications of heating and the colour of some of these rubies may also be called ‘pigeon blood red’based on SSEF reference standards; also accompanied by an appendix stating that the rubies possess extraordinary characteristics and merits special mention and appreciation. The rubies have been carefully selected for this necklace and exhibit a beautifully matching colour and fine purity. The small inclusions found by microscopic inspection and the analysed properties of these rubies are the hallmarks of rubies from the reputed mines in the Mogok valley (the majority of these rubies including the largest ruby) and Mong Hsu (southeast of Mogok). Their attractive and saturated colour- for some of these rubies poetically referred to as ‘pigeon blood red’-is due to a combination of well-balanced trace elements, which are characteristics for the finest rubies from Burma (Myanmar). Assembling a matching selection of natural rubies from Burma of this quality can be considered rare and exceptional
