An inspection of the metal should reveal expert hand craftsmanship. Navajo artists did not have access to machinery and used somewhat primitive tools to produce near-perfect results.

Stones in which the matrix is nearly perfect or the stone color is too blue may indicate the use of block turquoise or plastic.Learn more about Jewelry & Watches
