Colour and Clarity: According to GIA report, the sapphire is natural, with indications of heating. Two trillion diamonds are of H and I colour, I1 clarity. Please refer to the reports for details. In our opinion, the sapphire is medium deep blue colour, eye clean with lively brilliance. Upon 10x loupe, the sapphire is very clean, with only a few minor nicks on crown facets, not seen to naked eyes. Two diamonds have nice face-up brilliance. Condition: Platinum and karat yellow gold ring mount, in very good condition.
