Statement platinum cocktail ring centered with a very rare natural royal-blue Pailin (Cambodia) sapphire—an origin prized for saturated color and now scarce due to exhausted mines. The cushion brilliant-cut sapphire is four-prong set (9.64 x 8.28 x 5.21mm; 3.49 ct) and stated as unheated/untreated, surrounded by 12 round brilliant diamonds in four-prong settings totaling 2.30 ctw (E/F color, VS1 clarity). Weight 13.85g; size 7 (sizable); top measures 15 x 17mm. Stamped with maker’s mark and platinum assay marks.
