Vintage 0.90 Carat Ruby and Diamond Platinum Cocktail Ring – Circa 1940

A fine and impressive vintage French 0.90 carat ruby and 0.48 carat diamond, platinum cocktail ring in the Art Deco style; part of our diverse vintage jewellery and collections

This fine and impressive vintage ruby and diamond ring has been crafted in platinum.

The substantial, Art Deco style, stepped twist design frame is ornamented with a feature 0.90ct oval cut ruby, six claw set in subtle relief to the centre of the arrangement.

The ring is surrounded by eighteen very well colour matched diamonds in a combination of baguette, fancy and eight-cuts.

The diamonds are displayed within the stepped, twist design.

The bifurcated ring shoulders integrate with the main setting and blend seamlessly with the hallmarked ring shank.

The ring is hallmarked to the outer surface of the shank with the French import mark (owl), used for finished articles brought into France to be examined by the French assay office.

The ring has been independently tested using state of the art technology (Niton XL2 Analyzer) and verified as platinum.

This Art Deco cocktail ring is supplied with an IDGL diamond grading report card.

This vintage ruby and diamond ring is an exceptional piece. It makes a meaningful gift for milestone birthdays, anniversaries, or particularly for a July celebration, as ruby is the birthstone for July and symbolises passion and vitality. For collectors, the platinum mount and French import hallmark add further provenance and desirability.

When worn, this ring is at its best as a statement piece. Its sculptural form and balanced diamond detailing lend themselves beautifully to evening events, cocktail occasions, and formal gatherings where distinctive jewellery can take centre stage. Equally, for those with a bold personal style, it can be worn to elevate tailored daywear, allowing the rich colour of the ruby and crisp brilliance of the diamonds to bring confidence and Art Deco glamour to any ensemble.

This impressive vintage ring is fine quality set with very well colour matched, very high colour graded diamonds and a ruby that shows no signs of heat treatment.

The ring is an exceptional gauge of platinum and is in excellent condition with a French import mark to the outer surface of the shank.

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.
