Vintage Ruby, Sapphire and Diamond, Platinum Bilateral Ring

A stunning, fine and impressive vintage 1940’s French 0.90 carat ruby, 0.90 carat sapphire and 0.80 carat diamond, platinum hinged bilateral ring; part of our diverse gemstone jewellery collections

This stunning vintage gemstone ring has been crafted in platinum.

The full eternity channel setting is ornamented with twelve rubies and twelve sapphires, all square faceted cut.

This central setting is flanked with two hinged half-settings displaying an array of twenty-two pavé set transitional modern brilliant round cut diamonds, totalling 0.80ct.

These hinged settings allow the ring to be worn in a multitude of arrangements, from a single coloured gemstone band to an asymmetric bilateral and trilateral array.

The sides of the setting are plain and unembellished.

The interior of the shank features two stabilising supports; these allow the ring to pass over larger knuckles and sit securely on the finger.

This bilateral gemstone ring is hallmarked to the surface with the French import mark for platinum (masked man) and has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

The ring is supplied with an independent diamond grading report card.

This impressive vintage bilateral gemstone ring is exceptional quality, set with rubies and sapphires displaying fine colour, brilliance and presence; these stones have some surface wear in keeping with age.

The very well colour matched, very high colour graded diamonds display a fine white colour and brilliance.

The ring is an exceptional gauge of platinum and is in excellent condition.

The French hallmark to the surface of the shank has wear in keeping with age.

Lovely selection & excellent service

AC Silver has a stunning selection of antique and vintage items. Both of my brooches arrived right on time as indicated by the tracking. They are even lovelier in person and I look forward to wearing them for decades to come. Andrew and Gemma provided excellent communication and prompt dispatch. I would absolutely recommend working through them.

Excellent customer care.

I had to place the order over the phone as my internet was misbehaving. The lady who I spoke to could not have been more helpful and was particularly careful to get all the details correct. I was then informed about the collection and dispatch of the item purchased, by email. The item arrived as expected and it had been most well packed so that no harm could come to it. It was a delight to purchase this item from C6323, AC Silver, and I could not fault any aspect of their customer care. I was highly delighted with my silver mustard pot and it was much better than the pictures on the web site.
