is a variety of the mineral species corundum. Sapphires occur
in all colors of the rainbow with the exception of red, which
is ruby. The name corundum comes from the ancient Sanskrit
"kuruvindam", while the name "Sapphire"
comes from the Persian word "safir", meaning "beloved
of Saturn", (or Greek sapphiros). It is noted in several
texts that sapphire was the lapis lazuli of the ancient world,
probably because the stones both have the same intense blue
coloring. See jewelry
made with sapphire.
Sapphire is mined in Australia, Sri Lanka and Thailand. Other
producers are Burma, Kampuchea, Kenya and Tanzania. Sapphires
are commonly heated to improve their color and reduce cloudiness
that is caused by rutile inclusions. The rutile inclusions
are responsible for the "star" or "cat's eye"
in star sapphires.
