1.62 ct E VS1 Round Lab-Grown Diamond

The pavilion runs 0.17° shallow for its crown. A 33.3° crown at a 58.0% table wants 41.07°; this has 40.9°. Under-returned: flatter white glare, less depth of pattern than the geometry could deliver. Not a defect you would name across a counter, but it is performance left on the table.

Strongly brightness-biased (lean 0/100). The shallow crown and large table return light white rather than splitting it. Bright and clean indoors and under overcast sky, and it photographs well — but little fire under spotlights, and watch for a flat, glassy look if the contrast pattern is weak. Judge it in everyday diffuse light before concluding — that is where this make earns its keep.

The 58.0% table is larger than this crown implies — a 33.3° crown belongs with a 56.0–57.5% table. Mixed intent from the cutter, usually weight retention. It will read less decisively as either style.

From the certificate text: the comments carry no treatment statement either way — worth asking the vendor, since most CVD stones receive post-growth HPHT decolourising.

It sits on a gate edge — 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.

Top tier — score 91.2. 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.
