A stunning antique 1930s 1.94 carat diamond and 0.90 carat sapphire, platinum cocktail ring; part of our diverse antique jewellery and estate jewelry collections

This stunning, fine and impressive antique sapphire ring has been crafted in platinum.

The Art Deco design is ornamented with a central collet set 0.73ct Old European round cut diamond.

The central diamond is flanked on either side by a collet set round mixed cut blue basaltic sapphire.

The pierced decorated setting is embellished with a further thirty pavé set Old European round cut diamonds.

The elevated ring shoulders integrate with the main setting and blend seamlessly with the plain ring shank.

This 1930’s sapphire and diamond cocktail ring 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 certificate for the feature diamond, in addition to an independent diamond grading report card and a sapphire report card and certificate supplied by the Gemmological Certification Services, London.

A sapphire and diamond ring of this calibre makes an exceptional gift for milestone anniversaries, significant birthdays or important celebrations. Its distinctive Art Deco styling also makes it an appealing alternative engagement ring for someone seeking a piece with character and history. When worn, the combination of diamond brilliance and deep blue sapphires creates a striking statement, making it ideal for evening wear or special occasions. Supplied with independent certification for both the diamond and sapphires, this ring offers not only beauty but also assurance of quality, making it a truly special heirloom piece.

This stunning Art Deco cocktail ring is exceptional quality set with impressive basaltic sapphires, displaying a fine colour and brilliance, and very high colour graded old cut diamonds displaying a fine white colour, brilliance and presence.

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.
