Sterling Silver Navajo Style Necklace w Agate & Spiny Oyster(?) Pendant

This stunning necklace features a blend of warm earth tones. It features long oval facetted bead which I believe to be agate with silver spacers. The pendant is set in a handmade sterling silver setting and I believe the centre stone is spiny oyster? This was purchased with a lot that came with a number of items that came from the southwest. Cannot confirm that this is Zuni or Navajo, but it certainly has that flavour to it. Measures 18” in length with a 2 1/8” x 1” pendant. This is a stunning piece to wear with any Boho chic or southwestern styling.
