We have a wide variety of rings, and as with all our jewelry, any size diamond or gemstone may be added to any piece for an additional fee for the stone and mounting. Rings can be in 10 or 14Kt. gold, and all nuggets are soldered to the ring shank. We do need to know the ring size, otherwise ladies rings are shipped size 7 and mens are size 10, and arrive in a black velvet ring box.
