brilliancescope vs. idealscope

[Maxine]

Are brilliance scope and idealscope the same thing????? Do they do they "measure" the same thing, rather?

Hi Maxine,

The IdealScope and BrillianceScope are two very different tools.

The IdealScope is a small handheld scope which denotes the amount of light leakage in a diamond.

The BrillianceScope is a machine equipped with a camera which is designed to measure how much of your diamond is performing in regards to brilliance, fire and scintillation. This machine is of arguable precision but does have some value.

I hope that answers your question in basic terms.

This may help you understand the IdealScope a bit more

I don''t think there is an official answer to this, yet.

You can definitely read descriptions of how each tool works, and both are meant to rank (and help price) diamonds''s by their good looks. Each has it''s own recipe of what eaxctly constitutes such "good looks" and, as far as I understand, the results of these two tools CAN contradict one another. This is quite obvious when non-H&A rounds and fancies are concerned. Ideal, H&As are already so standardized, that either tool works just about as well - all they can discriminate is really down close to "splitting hairs" IMO.

With no "official answer", as said, here''s a hunch.
The Bscope is supposed to judge diamonds after their optical performance in strong light. Indeed, the tool itself uses super strong lighting in it''s black box. So some diamons that would not look that great in lower "normal" lighting conditions would still top the scales of the Bscope because they are flashy in super strong light. On the IdealScope, those stones show allot of black spots (talking about fancies). Even if the Ideal Scope images contain allot of white (total or partial lickeage), a few reflectors (=those facets that show black under the Iscope) are enough to compensate and yield top Bscope results. Sure enough those balck facets do look black in low light or if seen up clsose. Some black is good 9for fire and contrast) but at some point there is too much of this good thing in particular and the Bscope doesn''t pick that up.
This seems to apply to AGS0 that are not H&A too - there was some debate way back about how much "black" is too much. And the debate is still a tad opened

All IMO. I wish one of the Bscope users around here could chime in.

I used to have some examples of princess cuts somewhere on which I based these observations.

What particular shape are you after ?

Just trying to learn...nothing special in mind re: specific stones.....and the lightscope? Is that more like idealscope????
