Large natural untreated turquoise 925 sterling silver pendant

This is one of the best natural turquoise pendants that I’ve ever had. The stone is a 100% natural and not treated by any means. It has a tan matrix and Persian blue and green turquoise. The turquoise measures about 35 mm in 16 mm. It measures 45mm including the bail. The chain is for demonstration only and not included in this sale. In excellent vintage condition.
