Hello everyone, I''m new here and very glad to have found this site. Been lurking here for a couple of weeks. My head is swimming in details, and need a little assistance.

Also need some clarification on how to find out about light leakage. Thanks.

I don't think you have to worry too much about light leakage with this stone. It probably is an absolute blazing inferno.

An idealscope will show you the amount of light leakage a stone has. You can purchase one through the menu above for $25. Be sure and buy the calibration cz as well. Their info site on the idealscope will clue you in what to look for.

I'm posting a DiamCalc computer simulated IdealScope image from the statistics you posted. The results are very good.

Light Return (mono)…...: 1.00 Very Good
Light Return (stereo)…..: 0.98 Very Good
(Non) Leakage (mono)..: 0.98 Very Good
(Non) Leakage (stereo).: 0.98 Very Good
Contrast............................: 0.98 Very Good
(Non) FishEye Effect…..: 1.00 Very Good


-----------
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. The computer generates an image with “perfect” symmetry, which is rare. Also, the star/lower girdle facet lengths may be different 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 Sarin info is downloaded directly into the program. However, this "blind" reproduction should be helpful in considering the major light performance aspects..

Thank you so much for the information Richard, I was hoping that it looked good. All those numbers can be a little intimidating. I'll be able to see the Brilliantscope tomorrow.

Okay I have the The BScope and it shows the following:

White Light: Directly over the border of High/Very High.
Color Light: Almost off the Very High Scale.
Scintillation: Directly in the middle of Very High Range.

Thanks, Lynn
