WINTER GEMSTONE 2023 Long Black Onyx in Quartz Shard Necklace

This shard-like stone has translucent areas of clear-white, icy quartz, with a diagonal river of opaque black. It hangs on a long necklace of mixed chains and patterns, including curb and Half-Persian chainmaille, ending with a long length of spiral chain.

This chain has no clasp, and has a set length of 30". The stone in its setting is 2-3/8" tall.

Onyx is a variety of chalcedony that usually has patterns of parallel bands in the stone. Artificial treatments have been used since ancient times to produce the solid black color in black onyx.

Quartz is the second most abundant mineral on Earth and it known for its strength as a mineral. The Ancient Greeks referred to quartz as  krustallos, derived from the word  kruos, meaning "icy cold," because some believed it to be a form of supercooled ice.
