vintage Italian micro mosaic necklace, made in Italy

Description

Here is a vintage micro mosaic necklace from Italy. The necklace is 15.75 inches long from end to end. It has a spring ring clasp that works well. On the back of the necklace, the brass is stamped with the words "MADE IN ITALY." A little of the stamping is illegible, but you can make most of it out in the 6th photo.
The exact age of the necklace is unknown. I think it's from the Art Deco period, possibly earlier.
The necklace is in wonderful condition. Please view all 8 photos and zoom in for better views of the tesserae (the mosaic tiles).
