VINTAGE stamped Malachite & Sterling Silver earrings

VINTAGE Malachite earrings in great vintage condition. 

• Stone: Malachite 
• Style: Stamped sunray/sunburst, flared shape—classic Navajo-style work
• Markings: “Sterling” + a stylized hallmark (possibly a “B”)
• Not Marked “Mexico” or “Taxco” = likely not Bernice Goodspeed or Mexican origin

These look like they could be vintage Navajo or Southwestern studio work from the 1950s–70s.
