So, this color came in called Vitrail Medium, but it is an unusual presentation of that color, with them being more Coppery Salmon Pink/Orange with an Olive Green chaser instead of bright fuchsia with a lime-green surround.
This being an alternative 'dye lot', once they're gone, I doubt we'll see them again.
These are hand-painted Czech Glass by Preciosa.
This piece measures 14mm round.
It has a bright silver foil back with a slight concave spot where the design is.
