Gorgeous Vintage Turquoise and Silver Navajo Earrings

This pair of earrings features two fantastic blue stones that resemble Sleeping Beauty but they have a tiny brown streak of matrix, so I don't know what kind of turquoise it is for sure. The earrings are unsigned but are authentic as can be seen from the workmanship and materials. Classic 70s Navajo silversmithing. In wonderful condition, a bit of patina. Fantastic addition to any Native American turquoise collection.
