Art Glass Millefiori Pendant Amber and Copper with Orange Blue Green Flowers

This is an art glass pendant on a multi-strand 17' necklace of natural fibers and ribbon.There is a stamp on the bail that appears to read 18KGP. I'm assuming the bail is 18K white gold plated. The glass pendant measures 2" long x 1 1/8" wide and a little over 1/2" thick.  There are glittery copper accents and millefiori inside of the glass. Very pretty!
