Very nicely done; could be for either a man or woman. Plenty of detail and a very nice piece of stone - most likely dyed white buffalo turquoise (Howlite). With chain. One only. This was an estate item and appears to be way under valued.
Once our good friends with Turquoise Moon, who have 30 years of turquoise and sterling expertise get back by, we will have it re-valued ... unless it "flies away" before they get to come back on the road.
