Hi, this is a blind bag glass bead I received. It has clear barrel shaped glass with a pretty yellow wave near the core. It has bubbles in each dip or valley. Please note it is a blind bag bead, as noted with the "o" engraved on the silver cap. I suspect it was a prototype. The caps are sterling silver and stamped with the makers' marks and 925. This bead was used once and is in excellent condition. I am a bead collector, and I treat my jewelry well. Ohm Beads are compatible with most bead brands, including Pandora. Photos are of the item you will receive. Item will come in Ohm Bead brand packaging. Please ask questions before purchasing. Thanks, and pls check out my closet for more items!
