Turquoise is an opaque, rich blue-green stone that can be found in many places around the world.  It is considered a rare gem when found in finer grades and has been prized for thousands of years to it's unique coloring.  Recently, it's value has gone down due to the introduction of treatments and imitations that are now offered for sale. 

When buying turquoise beads and gemstones, make certain that you are buying an authentic stone and not an imitation.  Due to the pricing on genuine turquoise, the prices of these beads are slightly higher, thus the finished jewelry has a higher price.  Always check the description on finished jewelry carefully for authenticity.

Turquoise beads come in a variety of colors
from rich blue to light green
