A RARE RUBY AND DIAMOND RING
Set with an oval-shaped ruby weighing 7.04 carats, within an oval-shaped diamond surround, mounted in 18k white gold, ring size 5½
Accompanied by report no. 57532 dated 23 September 2010 from the SSEF Swiss Gemmological Institute stating that the 7.04 carat ruby is of Burma (Myanmar) origin, with no indications of heating; also accompanied by an appendix stating that the 7.04 carat ruby possess extraordinary characteristics and merit a special mention and appreciation. The ruby exhibits a well-saturated colour combined with a pleasant cutting style. Its vivid red, poetically referred to as "pigeon's blood", is due to a combination of well-balanced trace elements in the stone, typical and characteristics for rubies of the Mogok gemstone tract. Natural rubies from this size and colour represent a great rarity and the 7.04 carat ruby with its combination of outstanding characteristics is a very exceptional treasure
Also accompanied by report no. 1007320 dated 3 August 2010 from the Gübelin Gemmological Laboratory stating that the 7.04 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 a note stating that Burma has long been recognised as the locality associated with the most desirable rubies in the world. Within Burma (now Myanmar), the most famed region is the Mogok Valley, or Mogok Stone Tract, in the Katha district, North East of Mandalay. These Mogok-type rubies typically possess a red body colour and red UV-fluorescence. In addition, they may contain tiny amounts of light-scattering rutile silk and a swirl-like growth pattern. It is this combination of features which gives these rubies their characteristic appearance. The natural ruby of 7.04 carats described in the above mentioned Gübelin Gem Lab Report possesses a richly saturated and homogenous colour, combined with a high degree of transparency. In addition, this gemstone has been spared of thermal treatment. Such a combination of characteristics is rare in natural Burmese rubies of this size
Accompanied by five reports dated from 23 March 2009 to 26 August 2010 from the Gemological Institute of America and Gem Certification and Assurance Lab with the following details:
