Set to the center with a cushion-shaped ruby, weighing approximately 4.01 carats, within a circular-cut diamond surround, mounted in gold, ring size 6 ¾.

Accompanied by report no. 89400 dated 16 January 2017 from the SSEF Swiss Gemmological Institute stating that the ruby is of Burma (Myanmar) origin, with no indications of heating and the colour of this ruby may also be called 'pigeon blood red' based on SSEF reference standards; also accompanied by an appendix stating that the ruby possesses extraordinary characteristics and merits special mention and appreciation. The ruby exhibits an attractive and saturated red colour combined with an excellent purity. The small inclusions found by microscopic inspection are the hallmarks of rubies from the reputed ruby deposit of Mong Hsu, located in the green hills of the Shan State in northern Burma (Myanmar). Its attractive and saturated red colour, poetically also referred to as 'pigeon blood red', is due to a combination of well-balanced trace elements, which are characteristic for rubies from Burma (Myanmar). A natural ruby from Burma of this quality is rare and exceptional.

Report no. 16117019 dated 1 December 2016 from the Gübelin GemLab stating that the ruby is of Burma (Myanmar) origin, with no indications of heating and the trade colour is pigeon blood red.
