From Egypt to Mesoamerica and China Ancient peoples treasured this vivid blue gem worldwide. It’s a rare phosphate of copper that only forms in the earth’s most dry and barren regions.
The most prized turquoise color is an even, intense, medium blue. But some prefer a greenish blue, and some contemporary designers actively seek out avocado and lime green turquoise. Turquoise can range from blue to green. Generally pure saturated blue is the most valuable shade.
Turquoise is semi-translucent to opaque, usually light to medium blue or greenish blue. It might have veins of matrix running through it (matrix is the remnant of its surrounding rock). Spider web turquoise contains fine seams of matrix that form into attractive web-like patterns.
Turquoise is often fashioned as a cabochon. The dome shape sets off turquoise’s color, texture, and any matrix beautifully. In addition, manufacturers and artisans fashion turquoise rough into beads for strand necklaces, and into the small, flat pieces that are popular in jewelry inlays.
Store your turquoise jewelry in it's own box or bag separate from other jewelry to avoid scratches or other damage. Clean your turquoise jewelry with warm, soapy water, never with steam or ultrasonic cleaners.
