Art Deco Ruby and 1.88ct Diamond Marquise Ring in 18ct Yellow Gold

A stunning Art Deco 0.62 carat Mozambique ruby and 1.88 carat diamond, 18 carat yellow gold and 18 carat white gold set marquise ring; part of our diverse antique jewellery collections

This stunning, fine and impressive ruby and diamond marquise ring has been crafted in 18ct yellow gold with an 18ct white gold setting.

The pierced decorated, marquise shaped setting displays a 0.62ct round mixed cut Mozambique ruby, collet set to the centre of the design.

The ruby is flanked on either side by a feature collet set 0.30ct and 0.28ct Old European round cut diamond.

Six collet set Old European round cut diamonds are collet set vertically, flanking the ruby to the upper and lower borders.

The marquise shaped Art Deco design setting is framed by a further sixteen pavé set Old European round cut diamonds, completing the arrangement.

A subtle millegrain decoration embellishes the 18ct white gold setting.

The elevated 18ct yellow gold ring shoulders integrate with the main setting and blend seamlessly with the plain hallmarked ring shank.

The ring is hallmarked to the interior with the mark for 18ct gold (18).

This antique 1920s dress ring is supplied with two independent diamond grading certificates in addition to an independent diamond grading report card for the supporting diamonds and ruby*.

NOTE: * The Gemmological Certification Services (GCS) lab has verbally accredited the ruby originating in Mozambique and verifies that the gemstone shows indications of heating.

This ruby and diamond marquise ring makes a meaningful gift for milestone birthdays, anniversaries, or especially for a July celebration, as ruby is the birthstone for July. The combination of yellow and white gold enhances its period character while offering versatility within a fine jewellery collection.

When worn, the elongated marquise form creates a flattering, elegant line along the finger, making it particularly suited to evening occasions, cocktail events, and formal gatherings. Whether styled as a statement dress ring or chosen as a distinctive engagement ring for someone who favours vintage glamour, this piece offers confidence, colour, and timeless sophistication.

This stunning Art Deco gemstone marquise ring is exceptional quality set with a stunning ruby displaying fine colour, brilliance and presence.

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

The antique ring is a very good gauge of gold and is in excellent condition, with a clear hallmark to the interior 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.
