Vintage Southwestern Western Necklace With Natural Turquoise And Hematite

Vintage handmade necklace with natural blue / green / brown turquoise and natural black hematite stones. Southwestern / Western. Turquoise has a rich matrix and is, possibly, Royston. In very good condition, as pictured. 18" long. This type of turquoise is rare and quite expensive. Not sure where and by whom it was made, but Native American Indigenous tribes, like Navajo, used such kind of turquoise quite extensively.
