Looks good on holloway cut advisor
Total Visual Performance 0.8 - Excellent
within TIC range.


The cut advisor usually warns against nailhead or fisheye proportions.

Most likely it isn't going to have a nail head or fish eye.

However, the diamond's proportions doesn't seem to indicate one with ideal optics. Get an Idealscope or Aset to verify it.

Pavilion depth causes nail head or fish eye, the crown angle is a little low thats all it won't have as much fire as a stone with 34-35 crown angle but the pavilion depth of 43 is perfect and won't have any bad affect.

What makes you say that?

OP this diamond passes two rejection tests: it has a GIA cut grade of Excellent and it scores under 2 on the HCA. If you are interested, the next step is to obtain magnified images of the diamond looking directly into the table, and if the vendor can provide them, as for an Ideal Scope image. Most vendors, however, do not use or know what an Ideal Scope is, so unless its a regular PS vendor, then from here you will have to use your eyes and photography or the help of an appraiser if you want to judge further.
