Vintage Jewelry Buying Guide
Hallmarks, clasp styles, and settings can tell you more about a piece's age than the dealer's description alone.
Start with the hallmark
Most fine vintage jewelry carries a small stamped hallmark indicating metal purity (like 14K or 925) and sometimes a maker's mark. A missing hallmark isn't automatically a red flag on older pieces, but it's the first thing worth checking with a loupe.
Clasps and findings date a piece
Clasp styles changed over the decades — trombone clasps and C-clasps are generally earlier, while spring-ring and lobster clasps became more common later. A modern lobster clasp on a piece claimed to be pre-1950 is worth asking the dealer about, since clasps are commonly replaced during repairs.
Where to practice
Large multi-dealer venues like Saugatuck Antique Pavilion are useful for comparing many pieces side by side before you buy.
Vintage Jewelry Buying Guide FAQ
How can I tell if vintage jewelry has been repaired?
Look for mismatched solder color, a clasp style that doesn't match the claimed era, or stone settings that look newer than the rest of the piece.
Does a missing hallmark mean jewelry isn't valuable?
Not necessarily — some older or handmade pieces were never hallmarked. It just means you'll need to rely more on other dating clues.
