What’s 15ct Gold? A Hidden Gem in Antique Jewelery
Ever come across a piece of jewelry stamped "15ct" and wondered what that even means? You’re not alone — 15ct gold is a bit of a forgotten treasure in the jewelry world.
So, what is 15ct gold?
15ct (or 15-carat) gold means the metal is 62.5% pure gold, mixed with other metals like copper or silver. It’s kind of a sweet spot — purer than 14k, but a bit tougher (and cheaper) than 18k.
A blast from the past
15ct gold was mainly used in the UK from 1854 to 1932. It was super popular during the Victorian and Edwardian eras. After 1932, it got replaced by 14ct as the new standard — so any piece marked 15ct is almost definitely antique.
Why it's special
-
Rare: Since it’s not made anymore, it’s a collector’s dream.
-
Stylish: A lot of 15ct pieces have those gorgeous, old-school designs.
-
Valuable: Good condition + antique = solid investment.
Spotting 15ct gold
Look for hallmarks like "15ct" or "15k", sometimes alongside British stamps.
A little TLC
Since most 15ct jewelry is around 100 years old, treat it gently. Clean with mild soap and water, avoid harsh chemicals, and store it safely.
