An oval, cabochon cut piece of genuine Onyx is mounted at the heart of this debonair men’s ring. Each piece is expertly cast from the finest solid 925 sterling silver before being 2 tone plated in 18k yellow Gold and pave set with 160 of our signature white Diamondeau – flawless simulated diamond. These gems rate so high on the Moh’s scale of hardeness that they can even cut glass like a mined Diamond.
