I have had several. I gave all of mine away except the one I have with silver,real pearls, amethysts. It is beautiful. My bet is these are probably glass with silver plating. hopefully the listian who is auctiong this off will reply. It is beautiful and can be worn for a necklace. Wrap it around your wrist and have a bracelet, I have draped one length down my hand from wrist and around a finger. lots of ways to wear it. They can be cheap and expensive.Some are silver plated and others sterling. F&WThey make nice presents. IAs long as they are for older teens to ladies.
