This was purchased directly from the artist - David Christiansen- at the Tucson Gem & Mineral Show in Arizona.   It is 58 x 28mm with a substantial 4 x 10 loop at the top.  Looking at the back, there is a different design of a flower at the top and small flowers at the bottom.  The red dot in the center was a sticker for the show and is not part of the glass pendant.

This is a thick glass pendant at 9mm and shows much depth of design

Photos above are a good representation of the actual.
