What is 10k GTR stamped inside a gold ring?
The “10K GTR” stamp inside a gold ring likely indicates two things:
- 10K: This refers to the gold’s purity, meaning the ring is made of 10-karat gold. Gold purity is measured in karats, with 24K being pure gold. 10K gold is 10 parts gold out of 24, or about 41.7% gold, with the rest being other metals like copper or silver.
- GTR: This is likely a manufacturer’s or designer’s mark, which could represent the initials of the brand or the creator of the ring. It’s common for jewelers to stamp their products with a distinctive mark to signify their craftsmanship.
