I find this Native American piece to be rather Intriguing I do not know what the stones in the mosaic are, but they are rather Attractive The Band is Hand Hammered & the Design is rather Unique I wish that the Artisan would have signed it Crown measures 1/2 Inch by 3/4 of an Inch Ring is a Size 7 & 1/2 The Band is 1/4 of an Inch Wide A Great Addition to any Southwest Jewelry Collector
