Light entering the crown is turned back through the table rather than leaking out of the pavilion. This is the one thing a round brilliant must get right, and it does. It sits on the locus Sasián \u003ci\u003eet al.\u003c\/i\u003e (2007) identified as the best-performing set, and that Cowing (2005) calls the axis of Excellent.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBalanced\u003c\/b\u003e (lean 45\/100).

The geometry is as strong as certificate numbers can show: crown and pavilion in proper complement, the table where it belongs. This is the standard haus1919 curates to, and this stone clears it with room to spare. What remains — inclusion position and optical symmetry — is confirmed on the actual stone, which no certificate can show.\u003c\/p\u003e\u003cp\u003e\u003cem\u003e3D ray-traced simulation from certificate proportions. Not a photo of this stone. Accurate representation of optical performance, but it does not account for facet variations and does not show clarity or inclusions. \u003ca href=\"\/pages\/questions-and-method\"\u003eSee more\u003c\/a\u003e.\u003c\/em\u003e\u003c\/p\u003e","brand":"haus1919","offers":[{"title":"Default Title","offer_id":68128777437407,"sku":"H19-LG792667930","price":2060.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/2590\/3327\/files\/studio.webp?v=1792432726","url":"https:\/\/haus1919.com\/products\/3-10ct-f-vs1-round-lab-grown-diamond-lg792667930","provider":"Haus1919","version":"1.0","type":"link"}
