What does 20-12k gold mean?

20-12k gold typically refers to the gold content in jewelry or items, indicating a mixture of gold and other metals. In this context, "20" signifies 20 parts of gold out of a total of 24 parts, translating to 83.3% gold purity, while "12k" (which is 12 parts gold out of 24) represents 50% gold purity. This notation helps consumers understand the quality and value of the gold in the item. However, it's worth noting that the expression is somewhat unusual, as gold is typically referenced in terms of karats alone (e.g., 14k, 18k, 24k).
