This act added new rules for accuracy with stricter fineness of gold requirements. Prior to this law, pieces were usually made slightly under karat, as was standard in that era. Vintage and antique jewelry (pre-1981) may not precisely reflect the karat stamp, and it's common for the gold to be slightly under the stamped karat. Additionally, routine maintenance such as resizing, prong re-tipping, and other adjustments can also contribute to pieces not being exactly the karat gold that is stamped.\u003cli\u003e \u003cbr\u003eListed with ExportYourStore.com\u003c\/li\u003e","brand":"Unbranded","offers":[{"title":"Default Title","offer_id":67923660570686,"sku":"J7082_B3F5","price":570.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0110\/3311\/6730\/files\/57_45ca86db-a3db-4490-81b2-67857807e093.jpg?v=1792491889","url":"https:\/\/antiquecupboard.net\/products\/art-deco-10k-genuine-natural-black-onyx-and-diamond-filigree-ring-6-5-j7082","provider":"Antique Cupboard","version":"1.0","type":"link"}
