| About Ruby
Passionate, powerful, exotic and vivacious
red - the color of Ruby. Throughout history ruby has been known
to adorn mortals and immortals with its beauty and brilliance.
The dramatic color and the regal heritage make this precious
gemstone even more prized.
Ruby gets its name from the Latin word 'ruber' meaning 'red'.
The ancient legends from the east talked of rubies as the glint
of life - "a deep drop of the heart's blood of Mother Earth".
According to other legends, ruby was believed to be
self-illuminated, and was also referred to as the glowing stone. |

According to Hindu mythology the palaces of Gods are lit by
enormous emeralds and rubies. The Emperor of China used a ruby to light-up his room. More folklore talks of ruby as promoting
long, healthy and happy life. Women in ancient times used it as
a charm to assist in fertility, and warriors from Burma inserted
genuine rubies beneath their skin as they believed it would
protect them from being wounded in battle.
Traditionally India was regarded as ruby's classical country of
origin. Ancient Indian literature, composed some two thousand
years ago, has a rich store of knowledge about gemstones and
their effect on one's life. The term 'corundum', which we use
today for this particular mineral, is derived from the Sanskrit
word 'kuruvinda' meaning 'hard stone'. The Sanskrit word for
ruby is 'ratnaraj' meaning 'king of the gems'.
Prior to the 20th century, Rubies were considered more precious
than diamonds, and in the mid-16th century were even valued
around 8 times greater than comparable diamonds.
Ruby is the birthstone for the month of July and the anniversary
gift for the 15th and 40th years of marriage. It is the
astrological stone for the zodiac sign Capricorn.

Genesis of Ruby |
|
The stones from Burma (now Myanmar) are the finest quality
rubies available. These stones have the purest and the most
vivid red that can be imagined. The color is popularly known as
'pigeon-blood-red', but the term 'Burmese color' is a more apt
description. These rubies are rare, valuable and often found
adorning a connoisseur's collection. These stones are typically
found in Mogok, North of Myanmar. Here, the much celebrated
stones lie in a mountain valley surrounded by high peaks in a
tough terrain. Another important deposit is from a small town of
Mong Hsu in the North-East of Myanmar. These gemstones had a
purple black core with a bright red periphery. These stones were
initially not accepted in the jewelry market for the typical
color characteristic. But when it was discovered that heat
treatment could transform the dark core into deep red, the gems
became an instant hit.
Other sources of ruby include Vietnam (the celebrated 'Siamese
color'), Northern Pakistan in the Hunza Valley, Tadzhikistan,
Laos, Nepal, Afghanistan and India (Kashmir, Mysore and Orissa).
A new emerging source, East Africa, has lately emerged as an
important cradle of fine rubies.

Crystal to gemstone |
|
From the mines, the rough crystal is taken for lapidary. The
crystal is carefully cut into different parts optimizing the
size of each piece for the best color and quality available.
Once this is done, the best suited shape and cut for that
particular piece is determined. The crystal is then shaped and
faceted accordingly. The facets are important as they help in
reflection and refraction of the light from the inside of gem
which gives the gemstone its luster. A skilled lapidist can
transform a rough stone into an exquisite piece of jewel.
The transparent or the lighter hues of ruby are most often
faceted. In lighter hues it is important that the light that
enters the gem should reflect back evenly across the face of the
gemstone, making it vivacious and more lustrous. The darker
gemstones look good in all shapes and cuts. Rubies can be found
in a variety of cuts and fancy shapes including triangles,
squares, emerald cuts, marquises, pear shapes, baguette shapes,
and cabochon cuts (dome shape). The rare star rubies with an
unusual kind of tiny needle-like inclusions are cut in a
cabochon shape to display a six-rayed white star on its surface.

Know your ruby |
|
Ruby (Aluminum Oxide, AL2 O3) is the red
variety of the mineral corundum with a hardness of 9 on Mohs
scale. Corundum is the hardest of all minerals only next to
diamond, which has a hardness of 10 on Mohs scale. Higher the
level of hardness, better the chances of the gemstone's
resistance to scratches and abrasion. Also, the chemical
structure of ruby makes it very tough, helping in resistance to
breaking, chipping and cracking. The hardness of this gemstone
combined with the toughness makes ruby perfect choice for daily
wear.
Sapphire is the sister stone of ruby belonging to the corundum
mineral family. Red corundum is called ruby rest all are
sapphire. Even the pink variety with a tint of red is classified
as sapphire. The finest quality of ruby is the one that is
intensely saturated, pure red with no overtones of brown or
blue. This color is reflected in the gems from Burma which have
the much celebrated 'pigeon-blood-red' hue.
Rubies, like the other precious stones (diamonds, sapphires and
emeralds), are usually not free of inclusions. Flawless rubies are found rarely and are very valuable. But for the beauty of
the vivacious color, the inclusions are accepted. Moreover,
these inclusions are finger prints of the gems giving a distinct
character to each piece. It is said that a perfect ruby is as
rare as perfect love.
Up to 2 carats, rubies are readily available but the gems are
extremely rare in large sizes. Top quality rubies can be more
valuable than colorless diamonds particularly in sizes above 5
carats. For instance, in the year 1995, a ring mounted with
Burmese ruby weighing 27.37 carats was sold for $4 million at
Sotheby's in Geneva, Switzerland - an astounding $146,145 per
carat!

Treatmengts / Enhancements |
|
Like other gemstones, rubies are rarely found
perfect in nature - which is why these gemstones are
heat-treated to intensify or lighten their color or improve
their clarity. Heat enhancement for gemstones is a permanent,
stable process and an accepted norm in the jewelry industry.

Ruby buying tips |
|
The most important factor to be considered while buying ruby or
any gemstone for that matter is color. As a general rule for all
gemstones, more vivid the color, more valuable the gem. Stones
of Burmese origin generally command the highest prices. One
thing typical to rubies is that a vast majority of these gems
are "native cut" in the country of origin. Custom cut stones are
usually valued more per carat.

Ruby jewelry |
|
The passionate color combined with the excellent brilliance
makes ruby irresistible for jewelry lovers. Fine, large rubies
may be worth more than clear diamonds of comparable size. They
make elegant center stones for rings and pendants. Smaller
stones make great accents for these pieces as well as brooches,
bracelets, and earrings. Small rubies combined with diamonds
make lovely ornaments. Rubies look stunning against a backdrop
of white, black, royal blue or emerald green.

Ruby Care |
|
Ruby jewelry can be cleaned using hot soapy water, or mild
detergent. Brushing with an old tooth brush to remove dirt and
grease, or using a soft cloth damped in warm water cleans it
very well. Cleaning agents containing chlorine or harsh
chemicals, or petroleum products must be avoided. |
