The unique squash blossom necklace originated by the Navajo from three foreign elements. The silver beads were evidently evolved from two button halves soldered together to make a bead. The buttons were from Spanish clothing decoration. The "squash blossom" was evidently copied from the silver pomegranate blossom seen on the trousers of men from Granada, Spain. The Naja or Crescent shaped pendant was borrowed from the Spanish horse headstall or bridle which in turn was adopted from the Moors who probably got it by way of the Middle east, possibly Mongolia. It was known in many early civilizations; the earliest are solid gold najas found in stone age graves in Ireland. Whatever the origins, the Navajo had the great ability to combine these elements into a beautiful piece of jewelry and the other Indians of the Southwest improved upon it. The Navajo called the squash blossoms themselves "Beads Which Spreads Out"
