Vintage 2.23 Carat Marquise Diamond and 18ct Yellow Gold Full Eternity Ring

A stunning, fine and impressive vintage French 2.23 carat Marquise cut diamond and 18 carat yellow gold full eternity ring; part of our diverse diamond jewellery collections

This stunning vintage diamond eternity ring has been crafted in 18ct yellow gold.

The full eternity ring is embellished with a total of twenty-one individually claw set marquise cut diamonds, totalling 2.23cts.

The side of the shank is hallmarked with the French 18ct gold fineness mark (eagle’s head).

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

This vintage French full eternity ring in 18ct yellow gold can function as either a standalone statement or a luminous companion to an engagement ring. Its balanced proportions make it suitable for regular wear, while the diamond weight ensures it remains impactful for evening occasions. The French origin adds a note of continental refinement, making it an appealing choice for those who value both quality and provenance.

 

This stunning vintage 1980s eternity ring is excellent quality, set with very high colour graded diamonds displaying a fine white colour, brilliance, and presence.

The ring is an excellent gauge of gold and is in excellent condition with a clear hallmark to the side 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.
