The long oval has some very skilled lampworking techniques. The latticino is lovely and the floral design is full melt and skillfully executed. I have never seen this bead before, nor any round examples.

The two shorter ovals, I have no opinion, but they look good with the larger bead.

The round with black and white latticino 16 looks like India to be because I've had latticino Indian beads in other colors... but I might be wrong.
