Will a black light do?
Yes, a black light will work. In fact, I attached a photo that I just took 2 minutes ago. The left is a diamond with faint fluoro. The right is a CZ with no fluoro. I don't have a diamond with no fluoro (yet). It's actually a lot more obvious in real life than in the photo.soxfan|1461365836|4022612 said:Will a black light do?
