Art. 5205 - 20x8mm Vitrail Medium II (1)

The shape is called an Elongated Bicone, Art. 5205.

This long bicone shape is really a gorgeous bead for earrings and necklaces, or as a feature on a bracelet.  I don't think they would go well around a bracelet as long beads tend to not sit in the right position in a small piece like that.  Although you can certainly try it.  With the right spacer bead between it could work for your wrist size!

Quantity per pack:   1 bead - Art. 5205 Vitrial Medium II 20x8mm

The packaging indicates that the beads were manufactured between 1970 to 1980.
