This was purchased directly from the artist - GRUDA - at the Tucson Gem & Mineral Show in Arizona.  There is a closeup photo above that shows the artist's name etched in the glass.

It is hard to describe the beauty of this bead with abstract pieces of aqua, green, blue, and a little pink foil pressed in the glass at different levels and angles.  There is much play of color and light in this complex piece. The back is plain black that serves as a base for the colored foil.

This is a thick glass pendant of 9mm at the section created for the hole 19mm from the top.

Photos above are a good representation of the actual.
