Hi Rhino!
Sorry you didn't make it to JCK-Vegas. It would have been fun to hang out with you. Perhaps next year.
Regarding the GIA FacetScan-TM product: I believe I heard it was being produced for GIA by OGI.
Regarding the images (above) of you taking photos of stones in the DiamondDock-TM -- GIA does not use the bottom portion of the DD for viewing purposes. Instead they position the stones on the shelf that lays midway up the DD (you can see the notch for the shelf in one of your above images). I specifically asked one of the higher-ups at the GIA booth about this and he said that stones should be viewed from the midway shelf, and that GIA uses the lower area for storage of things like master stones, etc.
After seeing the DD in person I wasn't very impressed. I can't even agree with those that say the most redeeming quality of the DD is that at the very least it provides a "constant" (if not arbitrary) viewing environment by which you can compare several stones. This is because I noticed lots of unevenness in the lighting along the length of the viewing shelf with a few asymmetrical "hot spots" of light in the center when the LEDs were turned on. Rhino, I would propose that you are getting very different results from those of GIA by viewing stones at the bottom of the DD (further away from the light source) rather than the middle shelf. Not that I think changing the distance of the viewing area would derive any more conclusive results than what I've already witnessed. Frankly I can save my $1600 and accomplish the same thing for clients by positioning a stone tray on my desk and shining a fluorescent lamp and an LED lamp at the stone tray.
This is posted not in the spirit of piling on, but just to state things as I see them.
Kind regards,
Bill Scherlag
P.S. Happy Birthday, bro!
