Can someone please explain to me what those little stickers with various numbers and fractions mean? Typically there is a number and a fraction behind it and then a number below that it can be either smaller or bigger with another fraction and then sometimes there’s a whole number below that? I am including photos of a few crystals as examples. What I’m trying to find out is how you decipher those numbers and make use of them. I am finding crystals ,from the thousand that I have that are new old stock ,by trial and error.Please help.
