hello, I won one of your auctions for a purple pendant. I am interested in some of your beads, such as these. I have some necklace wires that are ready to have the beads strung on them, with the closing clasps already put on them ( in other words, it is a necklace as one would purchase in a shoppe, only without any beads on it . . .of these I have several) I am new at this, and I don't know the tech terms. Therefore, would you tell me which of the numbers when item name states this mm and that mm-which number states how big the hole in the bead is, so that it is not too small to slide it onto the necklace wire? Thank you so much.
