Turquoise Beads - All of our turquoise beads are sold 'by the strand' unless specified otherwise. Turquoise is one of the most highly prized minerals in the world. We offer turquoise in a variety of colors and many of the beads have varying degrees of matrix, which is the brown or black veining in the stone. Because turquoise is a porous stone it is commonly stabilized or treated to seal the surface. This process protects the color and increases its durability.
