Smart Glass uses recycled bottles melted & slumped into new uses to wear! The ring is sterling & adjustable. A layer of blues & greens is sandwiched in clear glass for lots of depth.
Beachy & makes a statement! Glass square is 1/2" x 1/2" & about 1/4" deep, too.
Easily adjusts (and stays put!) from about a 7 to 8.5+
