This type of fluorescence without careful visual inspection. Nickels, at 1.95 mm thick, are just shy of 2 mm. If you are out of pennies, nickels are another good reference. If you stack two pennies together, you can estimate how big a 3 mm sized bead is or use a stack of four to estimate the size of a 6 mm bead. Generally, it's not a good idea to buy a colorless diamond with Strong/Very Strong fluorescence.ĭiamonds, even they can sometimes look hazy with strong fluorescence, so never buy a stone with This gives you a point of reference for bead size.
