This is one gorgeous ring by Navajo jeweler, La Rose Ganadonegro!  The stones seem to glow with depth and are brilliant sky blue natural Kingman turquoise.  The setting is simple, with twisted wire around the bezels, and two sterling domes soldered between the two settings.  The band is a triple split shank.  "L. Ganado" and "sterling" stamped on the back.
