Would you like for CBI & ACA to cut MB/SB fluor stones like BGD?

Yes but the key words being vetted and discounted like the BGD line. Also eligible to trade in full product line up.

I'd also be more interested if they went above and beyond to further color test fluor stones. One in a totally free UV environment. One in normal UV exposure. And one in heavy UV exposure.

Such additional testing would give me confidence no color over grading occured and would give me an idea what color I could expect in different environments.

I think it might have been @John Pollard who posted previously to say that CBI don't (intentionally) cut stones with fluor because of their market value uncertainties, which could impact both the consumer and CBI themselves (re: trade-ins etc.) IIRC.

I know CBI do send stones back if they disagree with a stone's grading (whether too high or too low) so it would be interesting to know if they do longwave / shortwave / combined / sunlight UV testing, for example :)

Of course.

There might be some question if anything ought to be different about the cut in honor of this vanishing blue, keeping all of the precisson.

I don't care much either way.
For me fluorescence is not that important.
It can be cool if you hang out in disco bars with black lights :rolleyes:, but I don't.

I'm pretty sure any vendor I would buy from would screen out any rocks with that rare undesirable artifact of fluorescence.

It might have been. I wrote this "Singin' the blues" (get it?) article for my friends at HPD a while back, with some explanation. Essentially the confounder is a contradiction between blanket lifetime value guarantees and the chaotic way the diamond-industry devalues fluorescence.

From that article << If you are a fan of fluorescence Crafted by Infinity does have a Crafted to Order program. We will custom-cut a diamond with high fluorescence levels. But the restrictions and assurances will be more in line with the rest of the diamond world (no long-term buyback, etc.).>>

All conventional instrument testing is on the menu. More about the occasional rare bird that shows up in our inventory described in a post by @Wink from HPD, here.

Is now rock bottom yet? ,( The 35% discount mentioned in 'Singin' the blues' [short, blunt & eminently citable 'singin''!] is less than the numbers on my side of the screen; I am surprised.
