{"product_id":"4-06-old-mine-brilliant-cut-diamond-g-vs2-gia-certified","title":"4.06 Old Mine Brilliant Cut Diamond, G VS2, GIA Certified","description":"\u003cp dir=\"ltr\"\u003eA 4.06 carat old mine brilliant cut from Namibian rough. The old mine brilliant is the antique cushion style that predates the modern round brilliant, cut here by hand in the traditional manner rather than to modern optical formulas. The 53% table is small and the 63.9% depth is substantial, which together mean a high crown and the deep, chunky facet architecture that defines the style at its most characteristic. The culet sits slightly large and reads as an open point through the table. Light comes back in broad, deliberate flashes.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eAt 11.25 x 8.83 mm the outline is a soft 1.27 ratio, closer to a classic cushion square than to an elongated one. It reads as a large, substantial stone rather than a long one, and it centers well in a solitaire, a bezel, or a period-style setting with a wide shank.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eColor grades G, at the top of the near-colorless range and white enough to set in platinum or white gold without the mounting drawing warmth out of it. Clarity grades VS1, with cloud, crystal, feather and pinpoint plotted on the diagram. There is no comments line on this report, so what you see on the plot is the whole inventory of characteristics.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThe rough came out of Namibia, where diamonds are recovered from alluvial and marine deposits along the Atlantic coast rather than from open kimberlite pits. The Orange River carried these stones hundreds of miles to the sea over millions of years, and the journey destroyed anything with a structural weakness. What survived to be deposited on the Namibian coast is disproportionately gem quality, which is why the country's output has the reputation it does. Namibia is a Kimberley Process participant and mining is run as a partnership between the state and its mining operators.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e \u003c\/p\u003e","brand":"J.R.DUNN","offers":[{"title":"Diamond","offer_id":49092821385316,"sku":"M40-5160174","price":114005.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0685\/4193\/9812\/files\/1FZP608141_LOOSE_2.webp?v=1787938870","url":"https:\/\/jrdunn.com\/products\/4-06-old-mine-brilliant-cut-diamond-g-vs2-gia-certified","provider":"J.R.DUNN","version":"1.0","type":"link"}
