Colour and Clarity: According to GRS report, the sapphire is natural, of Sri Lankan origin, with no indication of heating. Please refer to report for details. In our opinion, the sapphire shows fine lines of asterism (star effect), of medium blue colour. Upon 10x loups, the sapphire shows silks and colour zoning, but generally clean to naked eyes. The diamonds totalling approximately 0.40 carats, about E to F colour, VS clarity. Condition: Karat mount, in mint condition.
