on a lot of light view 2 pics, you can see only half of the diamond lighting up intensely, does it mean that the other half doesnt light up at all, or will it light up just as much as the other half if you could tilt the diamond inside the machine?

Dear Dark.....
I would suggest that you go see the stone, where ever it is. Ask to see it in the B Scope viewer as then it will be apparent what is happening ( if this isn''t something that looks very different to the B Scope camera ). With the B Scope Viewer you get to see the affect of the different positions of light angle entry with you eye.
It probably is a very slight variation in the lower girdle facet angle or the pavilion main facets, only detectible at that angle of light entry.

Thanks guys,
I''ve attached a pic with this post. In it you can see not all of the diamond is intensely lit up. My question was whether the parts that are not as intensely lit up are poorer performing parts of the diamond? Or will they return light just as much if the viewing angle was changed?

Thanks for the question and posting the picture. That really helps.
In answer to your question dark, THAT STONE LOOKS LIKE A COOKER.
In the controlled lighting environment of the BrillianceScope it is showing where light reflects off of facets at varying intensities. You see ... there are certain crown/pavilion angle combos that produce greater or weaker intensities of light refraction. While the lighting environment is wonderful for exploring which combinations produce this phenomena, I will be the first to tell you that you will never see the diamond in that particular lighting environment. If you read my tutorial on the subject I say this explicity. It is making certain seperations that are impossible for the human eye to detect.
Based on that image I can take a wild stab how it performed on the rest of the light positions and I''m willing to bet it got very good results. Your eyes will not perceive these minor differences dark. It should be one of the most beautiful stones you''ll ever lay eyes on, at least with regards to direct light conditions. Without saying where you got hte graphic, if you assemble the other 5 (or even the last 6th image) I can help give you further assessment. If you''d like to know I can tell you alot more from the images than I can the bar graph.
Hope this helps.
Kind regards,
Jonathan

Thanks dark.
I can tell you beyond a shadow of a doubt that if this stone did not get 3 very high's it should have. If it didn't it would be in the reading for scintillation and if it read anything less than VH would be a mistake (also covered in our tutorial).
Judging from the images it also appears one heart may be every so slightly skewed but not to a degree that it would impact the face up appearance nor would be detectable with the human eye. So far all signals are green on this one.
Your judgement is very impressive! Yes it did get VH on all three. One heart had a bigger gap between it and the arrow as compared to the others, but this was a very tiny difference just as you predicted.Date: 9/13/2005 4:29:11 PM

I''d call it the study of the optical signature.
When you look at and photograph images of diamonds day in and day out for years you get to know them quite intimately. The answer to your question would require a short volume which would best be answered over the phone since I do not want to type all of that out.
If you''d really like to know drop me a buzz and I''ll be happy to explain with links and graphics as we speak. As long as I''m not at the counter or on the phone with someone else, my time is your time.
Peace,

Thanks - didn''t realize it was such a complicated thing - I was thinking maybe there was something particular to look for that would be obvious after you KNOW what to look for!
Back to Dark''s original question though, I too have wondered why some stones show large swaths of light return and others show very specific, symmetrical patterns in their images. Just my observation, and correct me if I am wrong, but it seems these symmetrical pics seem to show up more in smaller stones, and the larger patches in bigger stones. For instance, in the other light views he posted for his stone, you can see the symmetry in the pics. Am I making sense?
