Understanding "14KD15" on Gold Earrings: Purity, Quality & Design

The hallmark 14KD15 on earrings conveys several details:

1. 14K – 14-karat gold: 14/24 parts pure gold (58.3% gold). The remainder (41.7%) is alloy metals (copper, zinc, silver, nickel) for durability and color.
2. D – Quality mark indicating the piece meets a specific standard (often independent testing/verification). Regulations vary by country.
3. 15 – Likely a manufacturer's design or model number for inventory tracking.

Always verify authenticity with a reputable jeweler, as hallmarks can be counterfeited.
