(For some reason, I find flourescence an interesting subject.)

Diamonds with fluorescence come from all around the world so the conditions are not localized, but rough does have trends in some areas - Argyle is an example (Golconda also, if you''re a believer

).

The Premier mine in South Africa was associated with a lot of rough with blue fluorescence, including some of the "overblues" you hear about - and these have always been globally scarce. In 2003, on its 100 year anniversary the mine was renamed The Cullinan (you''ve probably heard of The Cullinan Diamond - the largest ever mined) and DeBeers sold the mine to a consortium last year.

You may have seen it already, but this GIA Fluorescence study is incredibly groovy. A must-read for fluorogroupies.

Thanks for the link. I love that article. I printed it and put it in my "diamond info. file".
