Vintage jewellery is everywhere at the moment, from car boot sales in Dublin to charity shop windows in Cork and Galway. It's no surprise really; you get one-of-a-kind pieces with actual history, usually for a fraction of what you'd pay for something new on Grafton Street. But with the boom in popularity comes a flood of reproductions and "vintage style" pieces trying to pass themselves off as the real deal. Here's how to tell the difference. Now don't get me wrong, I love costume jewellery, new jewellery, all of it really, but it's nice to know what you're investing in if something costs more.

Start With the Hallmark
A hallmark is your best friend when it comes to checking whether a piece is genuine. Irish hallmarked gold and silver carries the mark of the Assay Office of Ireland, based at Dublin Castle, usually shown as a crowned harp. A lot of vintage jewellery found here was actually made in Britain, so you'll also come across marks from Birmingham, London, Sheffield or Edinburgh assay offices, often alongside a date letter that tells you the exact year it was tested. No hallmark doesn't automatically mean it's fake, some older or foreign pieces were never required to carry one, but it's always worth grabbing a loupe or your phone's zoom to have a proper look at the inside of a band or the back of a pendant.
Check the Clasps and Findings
The little bits, like clasps, hooks and pin backs, tend to give away a piece's age faster than the design itself. Older necklaces often use box clasps, C-clasps or barrel clasps, while spring rings and lobster clasps became common from the mid-20th century onwards. Screw-back and clip earrings point to a piece made before pierced ears became the norm in the 1960s and 70s. If the findings look suspiciously shiny or modern on a piece that's meant to be decades old, that's worth a second look.

Feel the Weight
Genuine vintage jewellery, especially sterling silver and solid gold, tend to feel heavier and more substantial than modern costume jewellery. Cheaper reproductions are often made with lighter base metals or thin plating to keep costs down. It's not a foolproof test on its own, but if a "solid silver" ring feels suspiciously light, trust your gut.
Look Closely at the Craftsmanship
Handmade or early machine-made pieces usually show tiny imperfections, slightly uneven settings, hand-finished edges, or soldering marks that a laser-cut modern replica simply won't have. Stones set in older pieces are often held in place with claws or bezel settings rather than glued, so give any gemstones a gentle wiggle. If a "vintage" stone moves in its setting or looks a little too perfect and uniform, it may well be a newer piece dressed up to look old.
Ask Questions About Provenance
The seller should be as honest as they can be about a piece, be able to tell you at least where they got it and what markings or history they know about it. Don't be afraid to ask the questions.Â
Buy From Sellers You Trust
Whether you're browsing an antique fair, a Facebook selling group or an online shop, reputation matters. Look for sellers who photograph hallmarks clearly, describe the era and materials honestly, and are happy to answer questions before you buy. It takes a lot of the guesswork out of it, and means you can actually enjoy the hunt instead of second-guessing every piece.

At the end of the day, buying vintage is as much about the story as the sparkle. A little bit of know how means you can shop with confidence and end up with pieces that are genuinely as special as they look.
