That is roughly 2.3 crown-degrees worth of mismatch on a trade-off that only tolerates a fraction of one. Expect leakage in a ring just inside the table, which reads as a dull, lifeless zone rather than a hard dark centre. The Cut Group documented exactly this at 35.3°\/41.4° on a 57% table — “very unattractive leakage just inside the table”.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBrightness-leaning\u003c\/b\u003e (lean 25\/100). Whiter, more mirror-like return with less coloured flash. Reads well in diffuse everyday light and photographs cleanly — which matters if it sells from images.\u003c\/p\u003e\u003cp\u003eThe 58.0% table is larger than this crown implies — a 34.0° crown belongs with a 55.3–57.1% table. Mixed intent from the cutter, usually weight retention. It will read less decisively as either style.\u003c\/p\u003e\u003cp\u003eFrom the certificate text: the comments carry \u003cb\u003eno treatment statement\u003c\/b\u003e either way — worth asking the vendor, since most CVD stones receive post-growth HPHT decolourising.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eIt sits on a gate edge\u003c\/b\u003e — pavilion 41.4° on the 41.4° ceiling; table 58.0% on the 58.0% ceiling. IGI reports to a step wide enough that the true value could be on either side of the line. Treat the pass as provisional and let a re-measure settle it.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePasses\u003c\/b\u003e — score 73.1.

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":68170266050783,"sku":"H19-KQSDE","price":850.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/2590\/3327\/files\/studio_22ea07c6-e3a3-4601-9340-4ac5ce1e7a3b.webp?v=1792501340","url":"https:\/\/haus1919.com\/products\/1-59ct-e-vvs2-round-lab-grown-diamond-kqsde","provider":"Haus1919","version":"1.0","type":"link"}
