{"product_id":"3-30ct-old-mine-brilliant-cut-diamond-j-si2-gia-certified","title":"3.30ct Old Mine Brilliant Cut Diamond, J SI2, GIA Certified","description":"\u003cp dir=\"ltr\"\u003eThis is an old mine brilliant cut, the antique cushion form that predates the modern round brilliant. Chunky facets, a high crown, a small table at 53%, and a slightly large culet that shows as an open point when you look straight down through the stone. Those are the traits that distinguish an authentic old mine from a modern cushion, and they produce broad flashes of light rather than the fine, uniform sparkle of a contemporary cut.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAt 11.44 x 7.96 x 4.96 mm, the outline is noticeably elongated at a 1.44 ratio. The stone covers more finger than a squarer cushion of the same weight, which makes it well suited to a solitaire or a three stone with tapered sides.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eColor grades J. In a cut with facets this large the tone reads warm, which is part of the appeal in this category and sits naturally in yellow gold. Clarity grades SI2. Polish and symmetry are both Excellent. GIA does not assign a cut grade to antique or fancy shapes, so those two marks and the proportions are what you have to work with on the report.\u003c\/p\u003e","brand":"J.R.DUNN","offers":[{"title":"Diamond","offer_id":49092677599332,"sku":"M30-349132","price":32292.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/4193\/9812\/files\/1FZP608137_LOOSE_2.webp?v=1787935905","url":"https:\/\/jrdunn.com\/products\/3-30ct-old-mine-brilliant-cut-diamond-j-si2-gia-certified","provider":"J.R.DUNN","version":"1.0","type":"link"}
