Ohmsatte Inlay Zuni Buckle

Interesting Zuni buckle made by a member of the Silas Ohmsatte and Bertie Ohmsatt family, probably in the 1990s. Looks like the initial “R” Ohmsatte. Mosaic inlay on a sterling base – turquoise and I’m not sure what the other stones are. It’s really hard to do work this small and to do duplicate matching images. Back has a little discoloration but the front is in mint condition. 3” x 2” and for a 1 ½” belt.
