					Turquoise
  The distinctive color of turquoise continues to be popular in the world of fashion and
jewelry. This brilliant gemstone ranges in color from a vibrant sky blue to a paler
bluish-green. Turquoise is comprised of copper aluminum phosphate, with copper
creating the primary blue color, and green originating from the iron and a slight
amount of chrome. Additionally, turquoise stones often show a matrix of veins in
black, grey, or brown. The matrix is referred to as a cobweb, spiderweb, egg-shell, or
edisonite depending on the pattern of the veins.
  Turquoise is found as a filling or encrusting in the cavities of volcanic rock, or in the
form of nuggets. The most beautiful turquoise comes from Iran, but also originates in
the United States, Mexico, China, Afghanistan, and Israel.
  Turquoise is a relatively soft and sensitive stone. It has a hardness of 6 on the Mohs
Scale and is often subjected to some form of treatment in order to reduce its
sensitivity to scratching and color fading. Treating the stones with wax or synthetic
resin are common methods to improve durability while preserving the natural color,
and these stones are generally more valuable th an those treated with chemicals or
chalk to improve the color and appearance.
  Turquoise is completely opaque and therefore most commonly cut into cabochons or
beads to make stunning, fashionable jewelry. However, as with most gemstones, it
must be properly cared for with a few simple steps:         Protect     from     cosmetics
     Protect from heat and bright light Clean occasionally with a soft cloth Clean
once a year with diluted ammonia liquor
  While turquoise is beautiful any time of the year, it is the official birthstone of
December, as well as the Planetary stone for Aquarius, Taurus, and Sagittarius. You
