Turquoise + Gold Infinity Flower Czech Glass 13mm 9/16" # CZ 292
The back is glittery glass, which shines through the clear turquoise glass in front, so this little gem has some sparkle. 9/16", so a bit larger than 1/2" in diameter and about 1/4" deep with the shank. Shank has 4 tiny holes. Fabulous, Czech glass artisan button.
