| X dollars would not just double when you go to two
carats — it might triple or quadruple to 4X. Additionally the
crystals grow hexagonal pencils so it is very difficult to cut large
Rounds or big Emerald cuts from the rough. You can expect to pay 50%
more for round or emerald cut over the normal price for oval Rubies.

TONALITY: Along with the primary hue, tonality helps define
the color of Ruby. Almost all gemstones have a tonality of at least
50%. Perhaps it is easiest to explain tonality to suppose you had 2
gallons of white paint. And you begin to pour black white into one.
It would take some time for your eye to perceive a color
difference.
The best place to see tonality is to examine the edge of the
gemstone. This is the area that light has the least amount of
distance to travel through the gem. Do no look at the table area for
tone. Notice the blackish ring around the girdle or just
under the crown facets. That is tone. If the tone reached 100% then
you would have a black gem. Therefore a good red Ruby with 98% tone
may look like a Garnet when mounted. |

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. |
