Gemmato in Italian means full of gems. I think these beads appear to glow with the bits of brightly colored translucent glass, which are called frit. The golden background make the frit sparkle. The necklace has 1" gemmato beads,and the gold foiled beads. Spacers of gold tone metal. The necklace is 26" with a gold tone metal bow. Not marked. Excellent vintage condition. The variety of colors of the frit will enable you to add your favorite rhinestones and gems. Gemmato beads are fairly rare.
