This black and silver cocktail ring is nothing short of grand! A natural and large (1" long, 3/4" wide) black onyx gemstone is surrounded by sterling silver and sparkly marcasites. The big ring has a face/top area of about 1 3/8" long and 7/8" wide, and the ring is actually curved for comfort. This truly is a spectacular ring; the black onyx and marcasite border look amazing together. This is a great ring for men or women who enjoy such grand jewelries.
