We have 5 different kinds of beads, but to make a necklace you need to gather up some number of these beads. If you are collecting beads and want to swap or sell some of your type X to get somebody else's type Y, add your request or offer to this thread.
I have one bead of Nyanite and 4 beads of Ouzian. I would like to get more Ouzian beads; it takes 23 of them to make a necklace. It takes only 17 beads of Nyanite to make a necklace.
Other bead types are Caiyotite (17), Gnipperite (19), and Red Tiger Eye (19).
