Answer:
Most of jewellry are made of 22 karat to 10 karat of gold.
Explanation:
Ornaments and jewellry can't be made of 100 per cent pure gold or 24 Karat gold as it is very soft and delicate.
24 carat is pure gold so it has less strength to make ornaments. To impart strength, some impurities are mixed such as copper to make the 22 carat gold which is suitable for making ornaments. Therefore, as 24 carat gold is pure gold, it is weak to make ornaments.
