Karat measures the proportion of gold in an alloy out of 24 parts. Lower karats contain more non-gold metals, which can add strength or change colour.
Common Karat Levels
24K is close to pure gold. 22K is approximately 91.6% gold, 18K is 75% gold and 14K is approximately 58.5% gold.
Why Alloys Are Used
Pure gold is soft. Metals such as silver, copper or others may be added to improve durability and create different finishes.
Karat and Valuation
The tested karat determines the relevant rate per gram. The final amount also depends on eligible net weight.
