Hi,
I''ve read quite a few discussions here on the positives and negatives of the BrillianceScope. I read one post where someone suggested the BrillianceScope is only testing direct light and that dim or grey light might be different.
Does anybody have any opinions or factual information on the differences between diamonds seen in direct light and dim light that the BrillianceScope rates highly? -- Or on how less intense light changes a cut''s effectiveness in general? I am unaware if the designs of HCA, Ideal-Scope, FireScope, LightScope, etc. note differences that occur in dim light, so maybe this is not a complicated topic. I''m no expert, so please let me know if I''ve missed something.
Obviously in many rooms or on a cloudy day there may not be "direct" or bright light on the diamond. Is this a no-brainer -- in a dim room, does a "better" cut always look "better"?
(from these forums it is obvious that what''s "better" in a cut and even what''s better in a look is not always agreed upon)
Would scintillation be less important then? In dim light, could dim little flashes have less effect than an occasional broader flash?
What about brilliance in dim light?
What about fire in dim light?
Hoping for simple answers, noticed they don''t always exist around here.
Thanks for any help you might have -- I''m interested in buying soon, and just wanted a little more information.
By the way, thank you leonid for providing a place for the average diamond buyer find out information from people who have the experience.
