It is permissible for women to wear jewellery made of material other than gold and silver, but it is not permissible to wear rings made of anything other than gold or silver.
For men it is only permissible to wear a silver ring weighing less than 4.36 grams.
Those things that are not permissible for men to wear are also not permissible for na-baaligh boys.
It is haraam for men and boys to wear silk clothing, earrings, necklaces or even a silver ta’weez.
It is haraam to use gold or silver dishes and spoons, to eat or drink from gold or silver utensils and use toothpicks made of gold or silver.
It is not permissible to use surmah or oil from a gold or silver container. It is not permissible to use the surmah stick if it is made of gold or silver, and even to look into a mirror whose frame is made of gold or silver. This rule applies to both men and women.
