Robert Kelley (?) - Amethyst and Sterling w/ Gold Tone Edge Ring, Size 7.75 Orville Tsinnie but the sterling has tarnishedAbsolutely stunning sterling silver ring with a gold tone (possibly gold overlay or gold) outer rim. The ring is set with a large purple Amethyst that catches the light beautifully from every angle. While this ring is not signed by the artist, several similar and unsigned pieces have been attributed to Robert Kelley. This could be made by him, but I cannot make this statement with certainty.
