“14K CH” on gold refers to two things:
- 14K: This stands for 14-karat gold, which means the gold is 14 parts out of 24 pure gold, or 58.3% pure gold. The rest (41.7%) is made up of other metals like copper, silver, or nickel to provide strength and durability.
- CH: This could refer to the maker’s mark, a brand, or a country of origin. For example, “CH” might represent the initials of the manufacturer or a location code, but it’s not a standardized hallmark for gold purity.
If “CH” refers to the maker’s mark, you may need to check with a specific jewelry manufacturer or look it up in a catalog of jewelry hallmarks.
