Turquoise is among the oldest known gemstones- it has been mined since 3,200 BC.
It graced the necks of Egyptian Pharaohs and adorned the ceremonial dress of early
Native Americans. This robin egg blue hued gemstone has been attributed with
healing powers, promoting the wearer’s status and wealth, protection from evil and
brings good luck.
Turquoise is an opaque, light to dark blue or blue-green gem. The finest color is an
intense blue. Turquoise may contain narrow veins of other materials either isolated or
as a network. They are usually black, brown, or yellowish-brown in color. Known as
the matrix, these veins of color are sometimes in the form of an intricate pattern,
called a spider web.
To improve its color and durability, turquoise is commonly permeated with plastic, a stable enhancement. It is also
sometimes permeated with colorless oil or wax, which is considered not as stable as plastic. Some turquoise is dyed to
improve its color, but rarely, as this is an unstable enhancement.
Special care is required for turquoise regardless of whether or not it is enhanced. A porous gemstone, turquoise can absorb
anything it touches. Avoid contact with cosmetics, perfumes, skin oil, acids, and other chemicals. Avoid dehydrating it or
exposing it to heat.
