Black Onyx and Sterling Silver Square Bead Necklace

This is a sophisticated matinee or opera-length strand featuring polished black onyx gemstone beads. The primary design element consists of uniform, square-cut onyx beads with slightly rounded edges and a high-gloss finish, reflecting light with a glassy vitreous luster. Alternating between these larger geometric squares are small, round spacer beads, which appear to be sterling silver or smaller onyx rounds, providing flexibility to the drape. The construction suggests a professional stringing method, likely on silk thread or jewelry wire, finished with a sterling silver clasp (as indicated by the user's context of 'Sterling'). Physically, the onyx exhibits a deep, opaque black hue characteristic of high-quality dyed chalcedony. The beads are approximately 10-12mm in width. The condition appears excellent with no visible chips, cracks, or dulling of the polish on the stone surfaces. This style is reminiscent of Art Deco revival or late 20th-century modernist jewelry, combining bold geometric forms with a classic monochromatic palette. The craftsmanship is evident in the symmetrical alignment of the square beads and the consistent finish of the stone facets.
