Brutalist vintage rough cut diamond ring. The 18k textured yellow gold ring with a medium grey, raw uncut diamond nugget weighing approximately 20cts, enhanced with three, round brilliant cut, white diamonds. . Not a "Diamond" person... this is great alternative to the average engagement ring. The ring, in the manner of Arthur King ,is the same vintage. All the rage in the 70's , uncut stones were the darlings of the studio jeweler. Railing against the traditional staid jewelry of the previous generation, these "diamonds in the rough" were prized for their natural beauty. Honestly seductive. Signed "Andrew" Size 5.5
