Re: Article: Over Grading of Blue Fluorescent Diamonds Revis

Wow. Incredible article. Fig 6a is where I actually said WHOA out loud. I really liked your solutions to the problem in the conclusion, too. I am kind of surprised that it's still not rectified. Is it just not a widely known issue? ETA: As someone who has a stone that has been graded both Medium an...

You all were wonderful guests! Your enthusiasm for Esperanza and the passion for diamonds that we all share made for a celebration that none of us will ever forget. We appreciate so much the folks that came and all those who have been enjoying the event from afar. http://www.pricescope.com/files/ima...

Michael, Do you know of any study that actually measured the UV light levels and wave lengths in common indoor lighting conditions both office and home? Complex because you would need to measure at average diamond viewing heights and across a whole range of invisible and VV spectrums. The 2010 stud...

Re: Article: Over Grading of Blue Fluorescent Diamonds Revis

While many people in the trade believe that they see this effect and so tout it as a benefit, I have not seen anyone dispute your scientific findings. This raises the question - if UV is too weak in virtually all indoor settings to activate fluorescence and thereby cause a whitening effect, then wh...

Impressive work Michael.

One of the key takeaways from me, in addition to concern about color gradin...

Re: ASET test difference?

In terms of the amount of useful information a single image can provide, I think ASET stands alone. However, people commonly try to do too much with individual images. The important thing to keep in mind with ASET is that it is largely relativistic. That is, whether the color in the image is orangy ...
