Q: Is it permissible for men to wear diamonds, emeralds and other gem like jewellery?
A: According to the Hanafi Mazhab, it is permissible for men to only wear silver rings which weigh no more than one Mithqal (approximately 4.375 grams). Wearing a ring from any other metal should be avoided.
However, a male may wear a precious stone on the silver ring, like an agate, ruby, diamond or emerald.
And Allah Knows Best
