Ruby
The price of wisdom is above rubies, says Job in the Bible, implying
that rubies were highly prized in his time. Indeed, the respect
and appreciation for rubies has always transcended all geographical
boundaries and social class.
The gold coronation ring of the English kings contains a large,
tablet-cut ruby on which the figure of St. George's cross is engraved.
Around the ruby are set 26 diamonds. Rubies are generously represented
in crowns and scepters in the royal jewels of many nations.
Ruby has acquired special attributes from its admirers over the
centuries. It has been regarded as a symbol of freedom, charity,
dignity and divine power. The Burmese believed that gemstones
ripened like fruit. The redder the color, the riper the ruby.
A flawed ruby was considered overmature.
Large, gem quality rubies have always been very rare. The huge
gems described in medieval romances and oriental literature were
most likely exaggerated by the imaginations of ruby admirers and
creative authors or were actually garnets or spinels.
RUBY COLOR
Ruby and sapphire are the two varieties of the mineral corundum.
Their exceptional hardness is surpassed only by diamonds. Red
corundum is called ruby, and all other colors are called sapphire.
The cut-off between ruby and pink sapphire on one end and plum
sapphire on the other has long been a subject of controversy.
Of course, gem dealers want the gem they're selling to be classified
as a ruby because the name alone increases its value.
FAMOUS RUBIES
A few rubies have distinguished themselves because of their size
or extraordinary beauty and are being guarded for posterity The
Louvre in Paris houses the Anne of Brittany Ruby, a 105-carat
polished but irregular gem. The 167-carat Edwardes Ruby was donated
to the British Museum of Natural History in 1887 by John Ruskin.
This 167-carat gem was named in honor of Major-General Sir Herbert
Benjamin Edwardes (1819-68) who saved British rule in India during
the years of the Indian Mutiny. Two star rubies are displayed
in American museums. The Smithsonian displays the 137-carat Rosser
Reeves Ruby, and The American Museum of Natural History has the
100-carat Edith Haggin de Long Ruby.
RUBY SOURCES
The different geographical sources of ruby are known for characteristic
colors and qualities, although they all produce a variety of gem
material. Burma is famous for producing the greatest amount of
top quality ruby-a fine, clear, deep red. Thailand is known for
dark red to brownish-red stones. Typical Ceylon (Sri Lanka) rubies
are medium light in tone. And Africa is known for small, sheet-like,
purplish-red material.
Burma is the most important source of ruby today. Other producers
are the island of Sri Lanka-(formerly Ceylon), the countries of
Thailand, Kampuchea (Cambodia), India and Australia, various localities
in Africa and our own state of North Carolina.
PRIMITIVE MINING
Mining for rubies is done by primitive methods, much as it was
centuries ago. Miners stake out an area and dig down about 15
feet to unearth the gem-bearing gravel. They sift the gravel through
wire screens, then continue with a panning method similar to that
used for gold.
SYNTHETIC RUBY
A synthetic ruby is nearly identical to the natural gem in physical
appearance, chemical composition and optical properties and can
easily be confused with genuine ruby by unknowledgeable buyers.
Only a trained geologist can tell the difference by locating telltale
inclusions in the stone.
STAR RUBIES
Some rubies display a luminous star when viewed in the right light.
This is caused by the orientation of intersecting needles within
the stone. The light reflecting off them forms a star. Stars may
be seen on certain translucent stones that have been cut in a
dome shape.
A CLASSIC GEM
Ruby's dramatic color and regal heritage make it the choice of
the most discriminating jewelry lovers. Fine, large rubies may
be worth more than diamonds of comparable size. They make elegant
rings and pendants. Smaller stones are also set in these pieces
as well as brooches, bracelets, and earrings. Small rubies are
popular for use in anniversary rings to wear alone or in the company,
of diamonds. Rubies are stunning against a backdrop of white,
black, royal blue or emerald green.
MAKING A WISE PURCHASE
Since subtle differences in quality can make large differences
in beauty (and price), it is important to select your jewelry
from a professional who can guide you honestly and ethically in
your purchase. Our firm is a member of the American Gem Society.
As a condition of membership, we are re-examined each year to
meet the Society's high standards for knowledge, professionalism
and integrity. The AGS symbol is the hallmark of consumer protection
within the jewelry profession-as it has been for over 50 years.
Many gems are processed to enhance their natural beauty. Ask your
American Gem Society jeweler to discuss which techniques might
apply to the gem of your choice.
