Vintage 1970s X Flex Ring

What it is

This isn't a ring Aurate New York designed — it's one they found. The Vintage 1970s X Flex Ring is part of a curated vintage program developed alongside Louis Martin Jewelers, a New York institution that has been authenticating fine jewelry and watches since 1978. The X Flex silhouette — a crossover design with a supple, articulated band — was a signature of 1970s fine jewelry: architectural, a little daring, built to move with the hand rather than sit rigid on the finger. The two-tone yellow and white coloring is classic of the era, when mixing metals felt fresh and modern.

The case for buying vintage

At $698, you're not paying for Aurate's production margin — you're paying for sourcing, authentication, and the irreplaceable quality of something that has already survived fifty years. Vintage jewelry from this period was often made with more material weight and handwork than contemporary pieces at the same price point. The X Flex construction in particular requires precise articulation at the joints, the kind of detail that's genuinely rare to find intact. Louis Martin's authentication adds a layer of confidence you don't get from a random estate sale.

There's also the sustainability argument, which Aurate is right to lean into: buying a piece that already exists is categorically better than commissioning new mining.

What to know before you buy

This is a size 6.75, and it is final sale. Both of those facts need to land clearly before you add it to your cart. Vintage rings can sometimes be resized by a skilled jeweler, but the X Flex articulated band style is notoriously difficult to alter without compromising the design — we wouldn't count on it. If 6.75 is your size (or close to it), that's a genuine reason to move; if it isn't, this isn't the right piece.

The ring may show signs of wear. That's stated plainly by Aurate, and it's honest. Fifty years of life leaves marks — a small scratch on the shank, a slightly worn edge on the crossover — and those marks are part of what makes a vintage piece feel like an heirloom rather than a prop. If you need pristine, buy new.

Aurate's lifetime warranty does not apply here. For any future service needs, the contact is Louis Martin's watch and jewelry department directly (212-245-5566). That's a workable arrangement given Louis Martin's long track record, but it does mean you're outside Aurate's standard customer service orbit once it ships.

Who this is really for

Someone who already knows their ring size, appreciates the design language of 1970s fine jewelry, and understands that one-of-a-kind means one-of-a-kind. This ring won't be restocked. There is no waitlist. When it sells, it's gone — which is both the appeal and the pressure.
