GCAL and the Photomicrograph

[Cecilia]

Does anyone know anything about this tool? Can it reveal flaws, or is it mainly used to identify the stone and record it''s unique cut?

Thanks for any info.

A photomicrograph normally shows inclusions blown up to a high magnification. Because inclusions are generally unique in appearance, it might be possible to use such a photo for future re-identification if there was no easier way to be sure about the stone's identity. I doubt it would be a primary tool of identification.

Primary identifiers are shape, weight, dimensions, color, clarity, proportions measured by a Sarin/Ogi, laser inscription.

Secondary identifiers would be photos, clarity plots, UV fluorescence.

Thanks David,

Here is a partial example of what GCAL includes in their documentation. In your opinion what does this really show, and how would it compare to the idealscope instrument?
