This pendant is made with Sterling silver, and has a loop on the top that can accommodate most average size chains if you wish to switch it out. It will come on an adjustable sliding knot cotton cord.
All the sea glass I use is just how I found it (except for drilling a small hole). You can't make genuine sea glass in a machine as it takes years and years to be smoothed by the wind, waves and sand. The ocean creates a unique and layered frosted surface on the glass that captures the light with so much more texture.
Pendant measures 1 & 1/4" from top of post to tip.
