People are often quite transfixed by this pendant so it may not be a very good choice if you were to teach a class. But for all other occasions, it works great. It seems on the edge of the avant garde without much fuss and fun enough to not be intimidating. Made of thick 14g. sterling wire balled sticks that hang through a thick piece of hammered sterling that was 4g. half-round stock material. The disks are 20g. The pendant measures 3 ins. total from the 16 in. sterling cable. Has been stamped "STELZER" and "STERLING". The pendant has an oxidized patina but the cable does not. If you'd like the cable to, specify in the message to seller upon checkout.
