Vintage Navajo Ring of Silver Set With Green Stone

This vintage Navajo ring is set with the most unusual green stone. We think there's a good chance it may be a green jasper. Whatever it is, we're really loving it! It's such a simple silver setting with only rope work around it for detail, however, it looks so great on the finger! The green stone has tiny white inclusions in it that look almost like snowflakes.

The ring comes from a large Native American estate in Albuquerque. It is a size 6 3/4. The face measures 1 1/8" x 7/8". Unsigned.
