These are so beautiful! The surround is a fantastic metallic teal blue to bright cobalt with a slightly more blue iris. The color is called Bermuda Blue.
These are hand-painted Czech Glass by Preciosa.
The color changes depending on the angle, and I've attempted to show that in the photos.
This piece measures 18mm round.
It has a flat foil back with a slight concave spot where the design is.
Sometimes the foil backing is silver, and sometimes gold, but I'm not sure why, as they're not specifically ordered that way!
It DOES NOT have a hole in it!
You will receive one cabochon.
