What does 314k mean in ring?

In the context of jewelry, "314k" refers to the gold's purity, indicating that the material is 314 parts per 1,000 made up of pure gold. This translates to a gold content of approximately 31.4%, which is relatively low compared to standard gold alloys like 14k (58.3% gold) or 18k (75% gold). Such a low karat is uncommon in fine jewelry, as it typically suggests a higher alloy content, affecting the metal's color, durability, and value.
