Turquoise
is a mineral that is a hydrous phosphate of copper and aluminium,
that creates blue and green colored specimens. It is a rare and
valuable stone in finer grades and has been prized as a gem and
ornamental stone
for thousands
of years the world over. Around the 16th century,
from the French language, taken either from either the word 'turquois'
for Turkish or 'pierre turquin' meaning a dark blue stone.
Even
the finest of turquoise is fracturable, reaching a maximum hardness
of under 6. Color is as variable as the mineral's
other properties, ranging from white howlite to a powder or sky
blue, and from a blueish green to a yellow lime. The blue
is
attributed to idiochromatic copper while the green may be the result
of iron impurities or dehydration.
