Centering on an oval-shaped ruby weighing approximately 5.11 carats, within a half-moon diamond surround, each set to the reverse with a triangular-shaped diamond, elevated over a brilliant-cut diamond gallery, extending to the three quarter-hoop, mounted in 18k white gold, ring size 5, in a brown suede Etcetera case. With maker's mark for Etcetera 

Accompanied by report no. 59086 dated 25 March 2011 from the SSEF Swiss Gemmological Institute stating that the 5.11 carat ruby is of Burma (Myanmar) origin, with no indications of heating; also accompanied by an appendix stating that the ruby possesses extraordinary characteristics and merits special mention and appreciation. The ruby exhibits a well-saturated colour combined with an attractive shape. Microscopic inspection represents the hallmarks of the classical ruby mines from the Mogok valley in Burma (Myanmar). Its vivid and saturated red colour, poetically referred to "pigeon's blood", is due to a combination of well-balanced trace elements in this stone. A natural ruby from Burma of this quality is rare and exceptional

Also accompanied by report no. 11038257 dated 30 March 2011 from the Gübelin Gemmological Laboratory stating that the 5.11 carat ruby is of Burma (Myanmar) origin, with no indications of heating and this colour variety may also be called "pigeon's blood red" in the trade; also accompanied by an appendix stating that the ruby possesses a richly saturated and homogeneous pigeon blood red colour, combined with a high degree of transparency, and a finely proportioned cut. Such a combination of characteristics is rare in natural Burmese rubies of this size
