Colour and Clarity: According to AGL report, all oval sapphires are natural, of Burmese origin, with no indication of heating and clarity enhancement. All thirteen oval diamonds, according to GIA reports, are D to E colours, Internally Flawless to VS2 clarity. Plesae refer to the reports for details. In our opinion, the sapphries are matching, of saturated strong blue colour, eye clean. Upon 10x loupe, most of the sapphires have natural fingerprints or crystal inclusions, and a few have minor surface abrasions on crown facets, but not seen to naked eyes and very common in natural sapphires. Condition: Platinum mount, signs of normal wear, overall in very good condition.
