Ruby
The modern word Ruby is derived from the ancient
Latin term "Rubeus".The earliest record for the mining of Rubies goes back to more than 2,500
years ago in Sri Lanka. Historically, many believe that mystical powers
lie within this intensely colored red gemstone. When inserted beneath
the skin, the ancient Burmese believed that the stone generates a mystical
force, which protects the wearer from accidents and attacks. In the ancient
world, many believed Rubies to contain prophetic powers, enabling wearers
to predict their future based on the color changes of their gemstones.
The ancient Hindus enchanted by the color of Rubies considered them to
be "Ratnaraj" or the "King of Precious Stones".
Today, Burma is the world's largest provider of high
quality Rubies. Many consider Burmese Rubies from the Mogok Valley to
be the world's finest. Vietnam, Kenya, Tanzania and Sri Lanka are some
of the other providers of this truly enchanting gemstone. Thailand, with
large deposits near the Cambodian border, was previously the world's largest
provider of Rubies, but due to environmental regulations, the mining of
gemstones has been greatly reduced. Rubies and Sapphires are closely related,
having corundum as their base mineral. The difference in color occurs
because of the different trace minerals contained within each gemstone.
Thai Rubies tend to have a darker color and less intensity than Burmese
Rubies, which are known for their high quality and high price range; however,
very fine Rubies can be found in Thailand at very affordable prices. African
Rubies tend to have heavy inclusions, but beautiful stones with fine clarity
can be found, usually in the higher price range.

Rubies come in many different
shapes and sizes, providing great variety to gemstone lovers. With hardness
just below that of Diamonds, Rubies are one of the toughest gemstones,
and with no cleavage, breakage rarely occurs. This makes Ruby perfect
for all kinds of jewelry including Ruby rings, Ruby necklaces and Ruby
earrings. Another popular form of ruby jewelry is with the rarer yet equally
magnificent "Star Rubies". Today online "Star Rubies" have helped increase
the popularity of jewelry with Rubies.
Microscopic inclusions, sometimes called "silk", are a normal characteristic
of Rubies. However, heating tends to dissolve these inclusions. The existence
of inclusions provides traces to the Rubies' origin and can be used to
separate natural from synthetic stones. The inclusions within these gemstones
may also be evidence that a Ruby has not been heat-treated.Inclusions
do not affect the value of the stone as long as the brilliance of the
gemstone is maintained and they are not visible to the naked eye. Intensity
and uniformity of the red color are the factors used to determine the
price of Rubies. Highly valued Rubies are those with intense medium red
and uniformed color. Intense pink Rubies can be highly appraised as well,
if they are clear and beautifully cut.
The evaluation of Rubies should be done under different light settings.
When viewed under very strong light, Rubies may show very intense color;
however, when viewed under normal lighting, the gemstone may appear less
intense. Light is therefore a very important factor in determining the
true color of Rubies. To help assess their symmetry, Rubies must be judged
from their face up position and their overall beauty should always be
taken into consideration.
