Answered by Sidi Abu Yahya
Are platinum rings halal for men? same question for titanium, steel, and iron rings, please.
As-Salaamu ‘Alaykum
Yes, platinum, titanium, steel and iron rings are permissible, no matter what the value. Even a ring made of pure diamond or any other precious material would be permissible. The only exception is gold rings which are absolutely unlawful. A silver ring on the little finger of either hand is sunna.
