One of the first gemstones to be mined, turquoise has long been prized for it’s intense colors, which vary greatly from sky blue to green, depending on the quantities of iron and copper found in it.
Turquoise is a complicated, persnickety gemstone. Just the right type of minerals must be in just the right place for a very very long time (millions of years) before turquoise is finally created.
Egyptians prized Turquoise as a Life Stone. The oldest pieces of jewelry set with this gem are fourbracelets found on the mummified arm of Queen Zar. She ruled in Egypt about 5500 BC.
