I have the following stone to make a decision on by Friday:
1.53 RB
H VS2
7.47-7.43x4.55
depth: 61.2%
table: 54%
crown: 33.2
crown depth: 15.1%
pav: 40.7
pav depth: 42.7%
culet: none
girdle: 0.9-2.2% faceted (which is thin-med, right?)
polish/symmetry: excellent/very good
EGL-USA cert, listed as "ideal plus" (their highest cut grade, albeit a tad looser than GIA & AGS!)
HCA score: 0.8 (excellent w/in TIC range), scores excellent on everything but spread (VG). It looks (based on where the "x" lands) that this stone barely missed the criteria for GIA excellent grade. It meets criteria for "American Ideal Class" cut 1B (using AGA DIY cut grading, it misses class 1A w/ the pavilion [by .1%] and the crown angle).
IS image looks really good on this stone - lots of red/pink, nice black arrows (it''s not H&A), a few little triangles of white around the edges (the kind that help scintillation).
My main concern is the crown angle. I know it''s lower than what most people around here seem to like... what effects does an angle like that (combined w/ my other #''s) have? also are the dimensions okay? HCA rates spread as only very good - I can''t tell if the diameter is on the smaller or larger size for the weight.
I''ve been examining the stone in as much different lighting as I can find - so far it''s looking fantastic, but I don''t have a more ideally cut stone to compare it to, so I want to get some more opinions on the stats.
TIA!!
everyone here is so wonderful and helpful!
