Each suspending a cabochon sapphire weighing 17.59 and 15.29 carats respectively, framed by circular-cut diamonds, surmounted by a brilliant-cut diamond weighing 1.15 and 1.13 carats respectively, linked by brilliant-cut and pear-shaped diamonds altogether weighing approximately 2.45 carats, mounted in platinum.  

Colour and Clarity: According to SSEF report, the two cabochon sapphires are natural, of Burmese origin, with no indications of heating. Two round diamonds in the surmount, according to GIA reports, are of matching F colour, VS1 clarity, with Excellent Cut, Polish and Symmetry. Please refer to the reports for details. In our opinion, two cabochon sapphires are matching, of deep strong blue colour, eye clean. Upon 10x loupe, there are fingerprint inclusions, more in one stone, but all these internal features are not seen to naked eyes. Smaller round and pear-shaped diamonds are about F colour, VS clarity. Condition: Platinum mounts, in very good condition.
