Silver & Gold Onyx Necklaces

When is a black heart a good thing? When it’s made of shiny faceted onyx and dangling from a Ross-Simons onyx necklace! You'll even find onyx in other colors, too! White cultured pearls and black onyx beads intertwine… textured yellow gold is punctuated by shiny onyx discs… a glorious diamond chandelier ends in an onyx drop… all delightful examples of striking onyx necklaces here on the Ross-Simons website.

Scores more onyx necklaces call out to be treasured gifts or shiny staples of a day-into-evening onyx jewelry collection. Give an onyx necklace or an onyx pendant for the seventh wedding anniversary. (What “seven-year-itch”?) Onyx and pearl, onyx and diamond… enchant her with a surprisingly seductive onyx necklace.

Our designers love the endless inspiration of black onyx. It contrasts stunningly with every precious metal and brings out the true colors of other gemstones. Onyx necklaces spice up your days and nights with fabulous fashion. Go with onyx beads or onyx circles, charms or drops—set in sterling silver, white gold or yellow gold. They all make stunning looks in onyx necklaces and pendants!

Fanciful, exotic, and wonderfully affordable, onyx necklaces seem to speak of the many places in the world that onyx is found: India, South America, China, Madagascar, Mexico and the United States.

Our buyers did the treasure-hunting, our designers worked their magic—so now you can simply enjoy our onyx necklaces and onyx pendants—at lovely prices, too!
