Micro mosaic ring

My latest addition to the micro mosaic collection. i just found this ring today together with a brutalist ring, a mid cenury modern ring, an afghan tribal ring and a bakelite bangle.
The difference in timespan couldn t be much bigger, could it?
Its a 1900 costume jewelry brass and micro mosaic ring. Probably from Italy.
The tesserae arent super tiny, but much smaller then the ones they use today. They are all there. The only thing is, some of the 'morter' ( I m not sure of the word, the thing they use to glue the tesserae on the ring) has a different color, probably due to the brass.
i hope you enjoy!
