Pt950 1.75ct No-Heat Madagascar Sapphire & 0.83ctw Diamond Cluster Ring w/Report, 5.75
This platinum ring showcases a 1.75 ct round-to-oval mixed-cut sapphire of vivid medium-blue hue, certified by GFCO (Report AAP42162) as natural, Madagascar origin, with no evidence of heat treatment. The centre stone is secured in a four-prong basket and surrounded by a double-tier floral cluster of near-colourless round brilliant diamonds totalling approximately 0.83 ctw (F-G colour, VS clarity). Diamonds extend partway down the cathedral shoulders in shared-prong rows, while a pierced basket gallery maximises light return and minimises metal weight. The high-polish shank is stamped “Pt950” and presents in excellent condition with tight settings and only light wear.
