We acquired this diamond loose and pictured it in a minimal mounting with compass-point prongs to highlight its cushiony shape. This diamond was cut well over 100 years ago, when faceting and polishing technology was limited. The small table of this diamond, the cascading, steep crown facets, the roomy pavilion and (of course!) the open culet are all evidence of an old cutting environment. Set with a low profile. \u003cbr\u003e\u003cbr\u003eNote: This ring comes with a jewelry appraisal for insurance\/replacement as well as a GIA Report for the diamond.\u003cbr\u003e\u003cbr\u003eMeasurements: Size 5 US, 2.8g\u003cbr\u003eDiamond details: (1) .78 carat Old Mine Cut diamond, GIA #519198575, SI2\/K, (4.98 x 4.80\/4.18mm)\u003cbr\u003eMarkings: N\/A\u003cem\u003e\u003c\/em\u003e\u003c\/p\u003e","brand":"Jean Jean Vintage","offers":[{"title":"Default Title","offer_id":49234253775031,"sku":null,"price":2405.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6400\/7607\/files\/4EDF8682-91E4-4FAC-8EF2-E03F3F03278A.jpg?v=1790358686","url":"https:\/\/jeanjeanvintage.com\/en-fr\/products\/antique-18k-1910s-68-carat-si2-k-old-mine-cut-diamond-engagement-ring","provider":"Jean Jean Vintage","version":"1.0","type":"link"}
