Woops!! Please Delete, Ignore, .....

I just realized that the reports are of 2 different stones. Must of been an error at GOG.

Sorry.

Heres the correct one if anyone cares:

They seem to coincide with the correct reports.

neither and both....
they aren''t the final answer but are something I consider when available.
The B-scope has a longer track record and more is known about it.
Talk too Jon about it.

I sure would love to see a series of diamonds measured with both instruments. Regardless of the outcome I would be pleased to share the results.

The definitions of the three Gemex measures are not identical to the definitions of the three ImaGem measures. Therefore the three bar graphs of Gemex and the three numerical scales of ImaGem do not really equate to one another.

My understanding is that ImaGem will provide more closely repeatable grading of the same stone and more discrimination at the upper range of performance than the Gemex product. An open test would potentially help people to make some initial, yet honest, comparisons. Truthfully, I have little idea of the outcome of such a test. Let''s roll the dice if anyone wants to gamble.
