Vintage 70's Platinum Large 16.25 carat Aquamarine Cocktail Ring

A magnificent rock this is! The emerald-cut natural Aquamarine is estimated to weigh 16.25 carats, it has a stunning blue colour.... presenting to the eye like it has it's own internal light source! The bold yet glamorous, cocktail style ring was custom made in the 70's in a very simple but stylish design, hand-crafted in Platinum .... only the best material for this gem! The band features an inner 'U' shaped ring size adjuster allowing for a more flexible fit; suiting finger size J / 5 through to N/ 7. This inner ring size adjuster is fused to the inside of shank and aids in the heavy top staying upright. The 2mm- 2.4mm wide shank has a subtle round edge profile, and upswept shoulders giving extra support to the setting. The aquamarine is set into a tapered collet four claw setting with side support - the open style setting gives maximum light to the stone. Total height of setting measures 12.3mm. Stamped "PLATINUM" on the inside of band, although slightly obscured by inner ring adjuster, can partially be seen. There is another stamp on the opposite side with letter 'X'. Total weight of ring on jewellers scales is 12.25 grams. Appraisal: Retail replacement- AUD $11,130, as at 21st September 2015.
