Is there a scale that shows the different gradients of flourescence in diamonds? Like how can one tell a SBF from a VSBF. I can compare what I have against what I have, but it's not like having a "master" so to speak.
And what, if any, other colors can flouresce in diamonds? Or is blue it?
Just a caveat, those pics were taken under controlled conditions and may or may not correspond to what you'll see at your local disco or with your little black light bulb carried into the closet.
