Neither. Diamonds are minerals and one of the hardest substances known, so it can't be struck into coins. Platinum is a metal, but circulating coins are made of base metals like copper, nickel, aluminum, etc. Gold, silver, and platinum are used only for coins made for sale to collectors and investors.
