उत्तर

The 24-carat is pure gold. Ornaments that are made from 24-carat gold, which is pure gold, are very rare since pure gold is very soft and is prone to wear and tear upon usage. Therefore, 22-carat gold is generally used, containing a small amount of copper, silver, and other metals to improve wear resistance while retaining its elegance.
