Colour and Clarity: According to both Gübelin and SSEF reports, the cushion sapphire is natural, of Burmese origin, with no indications of heating, and its colour is considered "Royal Blue" colour in trade; also accompanied by Gübelin information sheet stating that this sapphire is rarely found in nature. Two side diamonds, according to GIA reports, are matching, F colour, VS1 and VS2 clarity respectively. Please refer to the reports for details. In our opinion, the sapphire is of saturated blue colour, very clean to naked eyes and lively. Upon 10x loupe, there are some minor silks at one corner, but not noticeable even under loupe check. Condition: Platinum ring mount, in very good condition.
