The pavilion runs 0.20° steep for its crown. A 33.6° crown at a 58.0% table wants 41.01°; this has 41.2°. Within the tolerance the published trade-off allows (1° of crown buys about 0.2° of pavilion), but it spends most of that budget. Expect a slightly enlarged table reflection and a marginally darker centre when you lean in.

Strongly brightness-biased (lean 5/100). 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 33.6° crown belongs with a 55.8–57.4% table. Mixed intent from the cutter, usually weight retention. It will read less decisively as either style.

From the certificate text: comments state As Grown — no indication of post-growth treatment.

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 91.3. 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.
