{"product_id":"blue-heart-necklace","title":"Vintage Blue Heart Rhinestone Halo Pendant Necklace, Clear Crystal Cluster, Gold Tone, c. 1970s–80s","description":"\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA vivid blue heart rhinestone sits at the center of a starburst halo of clear prong-set crystals, small, precise, and brighter than its size suggests. The combination of a colored heart stone with a clear diamond-like surround was a popular format in the 1970s and 1980s, echoing the look of fine sapphire cluster jewelry at a fraction of the cost. A small maker's mark is present on the reverse but partially illegible, worth examining under magnification before listing.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMaterials\u003c\/strong\u003e Gold-tone base metal pendant; blue and clear rhinestones; dark silver-tone curb chain (possible replacement)\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCollected by Mineral and Matter\u003cmeta charset=\"utf-8\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eDetails\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"[li_\u0026amp;]:mb-0 [li_\u0026amp;]:mt-1 [li_\u0026amp;]:gap-1 [\u0026amp;:not(:last-child)_ul]:pb-1 [\u0026amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3\"\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eEra: c. 1970s–1980s\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eMarkings: Partial maker's mark on pendant reverse, illegible; buyer to verify\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStyle \/ design notes: Heart-shaped blue rhinestone center; eight clear round rhinestones in starburst halo setting; prong set throughout; double bail\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eStone notes: Blue heart rhinestone center; clear round rhinestones in surrounding halo; all prong set\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eFunction: Pendant necklace\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eColor: Gold tone, blue, clear\u003c\/li\u003e\n\u003cli class=\"font-claude-response-body whitespace-normal break-words pl-2\"\u003eCondition: Good vintage condition \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eMeasurement:\u003c\/strong\u003e Pendant 0.5\"; chain 18.5\"\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eCollected by Mineral and Matter\u003c\/strong\u003e\u003c\/p\u003e","brand":"Mineral and Matter","offers":[{"title":"Default Title","offer_id":48540091908331,"sku":null,"price":24.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0345\/9569\/files\/BlueNecklace.png?v=1779656769","url":"https:\/\/mineralandmatter.com\/products\/blue-heart-necklace","provider":"Mineral and Matter","version":"1.0","type":"link"}
