RARE RUBY AND DIAMOND RING

Centring on a cushion-shaped ruby weighing 12.28 carats, surrounded by eight oval diamonds together weighing 6.01 carats, mounted in platinum and 18 karat yellow gold. Ring size: 6

Colour and Clarity: According to both Gübelin and GRS reports, the ruby is natural, of Burmese (Mogok) origin, with no indication of thermal treatment. Also accompanied by a GRS Platinum Award, stating that it is "very rare combination of size over 10ct, from the classical mining area of Mogok, excellent color and spared of thermal enhancements". Surrounding diamonds, according to GIA reports, are D to F colours, VVS1 to VS2 clarity. Please refer to the reports and Platinum Award for details. In our opinion, the ruby is of strong red colour, slightly included to naked eyes. Upon 10x loupe, there are natural inclusions, such as silks and fingerprints, not surface reaching. Condition: Platinum and karat gold ring mount, in very good condition.
