One had opaque glass beads (the one in the picture) and the other has very tiny freshwater pearls. At least I think they are, it's hard to know when its vintage.
So, for a new piece I have paired the old with the new. The longer strand is the vintage rosary chain with the opaque glass beads and the shorter is an oxidized sterling silver chain with a briolette wrapped in oxidized sterling silver wire. It's very pretty on...now if I can get my daughter to model it for me.
