Gorgeous large Zuni natural turquoise cluster pin stamped with initials HV.  This is a Zuni piece rather than Hopi Homer Vance who was a fabulous early smith back in the 20's to 1961 .  I'm including this because looking up initials it says Homer Vance.  His work would look more like Navajo jewelry in the earlier days.  This beautiful pin is most likely from the late 60's to 70's period.  Perfect piece to wear to Gallup Ceremonial!   3.75" round
