This is Rainbow Bella by Sue Rioux.
Each of the 8 sides of the body of the kaleidoscope are a different color stained glass strip soldered together with Sue's signature copper solder and decorated with dots of solder on each end. The oil cell consists of a variety of glass and baubles creating a colorful 5 point star mandala.
This is a perfect gift choice for all ages and when space is a concern because it stands on its eyepiece end. It measures approximately 6-3/4" long x 1-3/4" in diameter.
Signed and dated by the artist. 'Sue Rioux - 2018 - Bella'
