A piece of jewelry!

K金375 refers to a type of gold alloy, specifically 375/1000 gold, also known as 9K gold or 375 gold.

Here's what it means:

* K stands for karat, which is a unit of purity for gold.
* 375 represents the gold content in parts per 1,000、In this case, it means the alloy is 37.5% gold.

So, K金375 is an alloy that contains 37.5% gold, with the remaining 62.5% consisting of other metals like silver, copper, and zinc、This alloy is often used in jewelry making, particularly for more affordable and durable pieces.

9K gold (375) is a popular choice for jewelry in some parts of the world, especially in Asia and Europe、It's less expensive than higherkarat gold alloys like 14K (585) or 18K (750), but still offers a nice balance of durability, affordability, and aesthetic appeal.
