I really like the dichroic glass look with the gears overlaid. Whenever you turn it in the light there is a cool color change to the piece, accentuated by the lines in the specialty film that adds a great geometric pattern. I don't make these ones to glow yet, but eventually. Thanks for taking a look, and check out our other goodies:) Size 1 inch wide by 1 inch tall and built up in a hypoallergenic base metal bezel. The chain is hypoallergenic black and 21 inches long.
