Buying a diamond ring

Diamonds in vintage rings are usually older cuts: old mine (cushion shaped, made before about 1890), old European (round, with a small table and a visible culet, roughly 1890–1930), rose cut (flat-bottomed, domed facets) and transitional cuts. They sparkle more softly than a modern brilliant, and many buyers prefer them for that. Weights in titles are often estimates: a certificate or a jeweller's valuation is worth more than a seller's guess.

How we compare vintage rings

Vintage and antique rings are one-offs, so price comparisons need care: two rings of the same era, stone and metal can differ a lot in stone quality and condition. We compare each ring only with rings that share its era group, main stone, metal and style, and, for diamond solitaires and three stone rings, its carat weight.

Where can I buy 1 carat diamond rings in the UK?

eBay UK has one of the biggest choices: 1,932 1 carat diamond rings listed today from antique dealers, jewellers and private sellers. This page shows all of them in one place, with the fakes, "vintage style" copies and damaged rings filtered out and each ring priced against similar ones.

Are 1 carat diamond rings on eBay genuine?

Most are, but not all. We leave out any listing that calls itself "vintage style", "inspired" or a reproduction, and anything with cubic zirconia, moissanite, plated or "gold tone" metal. Before you buy, look for a clear hallmark photo, ask how any stone was tested, and prefer sellers with a returns policy and a long feedback record. The green shield on a ring means a Top Rated seller or one with 98%+ positive feedback from 50+ buyers.

Can a vintage ring be resized?

Usually, yes: a jeweller can make most plain-shanked rings one or two sizes bigger or smaller. Full eternity rings, rings with stones all round, and some very old or thin shanks are harder or impossible to resize. Filter by UK size on this page to find rings that already fit, and check our ring size guide.

How do you know a ring is a good price?

We compare each Buy It Now ring with similar rings listed today: the same group of era, main stone, metal and style, and for diamond solitaires and three stone rings the same carat band. A "Good price" ring is at least 30% under the typical price of at least eight similar rings, from a seller with a good record. Anything 50% or more under is flagged "check carefully" instead.
