A commanding estate cocktail ring, this 14 karat yellow gold, black onyx and diamond statement piece is a study in bold geometric refinement. The elongated rectangular bar of jet black onyx measuring an impressive 19.85 by 4.93 millimeters dominates the face of the ring. Its mirror polished surface catches the light with a deep, lacquer like gleam set beautifully against the warm luster of solid 14 karat yellow gold. The black onyx bar is set vertically, creating a dramatic elongating effect on the finger that is unmistakably in the spirit of the modernist jewelry movement of the 1970s and 1980s, when bold geometric forms and graphic contrasts between stone and metal were hallmarks of fine jewelry design. Flanking the onyx on each shoulder are three single cut round diamonds per side, six stones in total, totaling approximately 0.06 carats, graded I color and I1 clarity. Their bright sparkle provides a luminous counterpoint to the deep black stone at center. The mounting features a refined split shank, adding architectural interest and lending the ring a visual lightness that balances the substantial face. The piece weighs 5.5 grams and is currently size 6.75. An ideal choice for collectors of vintage modernist jewelry...
