The crown angle is a bit shallow, but with a medium girdle you shouldn't have to worry about chipping, and it (the crown angle) seems to work well in combination with the estimated average pavilion angle (approximately 41.1').
Keep RockDoc's cautions in mind when viewing these POSSIBLE results generated by the DiamCalc's Light Return Analysis, as well as the POSSIBLE simulated
IdealScope image attached.
This stone probably majors in "brilliance" (white light return), while minoring in "fire" (colored light return) and "contrast" (the black-white-black-white scintillation effect). All in all, the numbers aren't bad at all, along with the simulated I.S. image, and the price seems reasonable.
Be sure and have it checked out...

IdealScope- In general, the darker pink areas indicate areas of greater light return, with the lighter pink areas indicating areas of lesser light return. The black areas indicate areas of greater contrast, with the gray areas indicating areas of lesser contrast. The white areas indicate areas of light leakage. A good explanation of the
IdealScope image along with examples can be found at https://www.pricescope.com/idealscope_indx.asp
Disclaimer- The facet arrangement and symmetry of the image will probably vary from your actual diamond, which may affect the light performance indicated, sometimes dramatically. The image shown has perfect symmetry, which is rare, and the star facet/lower girdle facet lengths may vary from your diamond. The computer simulation is reproduced best when the actual diamond is being viewed and the image "tweaked" to the appearance of the diamond, or when the Sarin data is downloaded directly into the program. However, this "blind" reproduction should be helpful in indicating the major light performance aspects.
