1980s Onyx Collar Statement Necklace in 14k Yellow Gold

This 1980s statement collar necklace is made of triangular 14 karat yellow gold links with a round black onyx centerpiece. The onyx is surrounded by a pave halo of 55 round brilliant cut diamonds, each measuring 1.75mm and .02 carats, giving a total diamond weight of 1.10 carats. The diamonds have SI1/SI2 clarity and H color, creating bright contrast against the dark onyx stone.

At 16 inches long, the necklace rests at collarbone level, making it visible but not overwhelming. The geometric design with alternating gold triangles leading to the centered stone and diamond arrangement captures the bold jewelry style typical of 1980s fashion.
