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 14mm round.
It has a flat foil back with a slight concave spot where the design is.
It DOES NOT have a hole in it!
You will receive one cabochon.
