The rectangular onyx frame holds a single cut diamond at its center—the K color grade means the stone carries a faint warmth, while the I1 clarity indicates inclusions visible under close inspection. The .005 carat diamond adds a subtle glint against the dark onyx background.\u003c\/p\u003e\n\u003cp\u003eThe 19-inch chain is permanently attached to the pendant and secures with a spring ring clasp. The yellow gold setting provides a rich contrast to the deep black onyx, creating a bold geometric look that sits nicely at collarbone length.\u003c\/p\u003e","brand":"Filigree Jewelers","offers":[{"title":"Default Title","offer_id":52050768986400,"sku":"19254","price":595.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0680\/5025\/6160\/files\/19_Vintage_Retro_Diamond_Onyx_Pendant_Necklace_10k.jpg?v=1785439329","url":"https:\/\/filigreejewelers.com\/products\/19-vintage-retro-diamond-onyx-pendant-necklace-10k","provider":"Filigree Jewelers","version":"1.0","type":"link"}
