In many ways buying a color gemstone is easier than purchasing a diamond.
A color gemstone is valued primarily by the depth and saturation of its
is the primary factor when evaluating a color gemstone. The tone and
hue of color you should look for will depend on the type of color gem
you choose. If the gemstone is blue as in a blue sapphire, avoid "overcast"
shades of grey or green. For rubies, the ideal color is "Pigeon's
Blood Red", thus a tendency towards pink will devalue the ruby.
Green emeralds should avoid yellow. Thus, a deeply saturated color and
true hue of the gemstone is what will set it apart from the rest. In
addition, look for an even distribution and purity of color when viewing
the gemstone face up.
is important to note that a color that appeals to you may not be the
recommended color for that specific gem. Find a color that appeals to
you, you are going to be the one enjoying it!
is less of a factor when evaluating a color gemstone. The amount of
inclusions a color stone possesses depends on the type of gem. For example,
most emeralds naturally have eye visible inclusions which do not affect
the value of the gem, while most other gemstones possess no inclusions
- Therefore, clarity should be evaluated on the basis of the type of color
stone. A good rule of thumb is to look for a gemstone that does not
have the inclusions under the table area. Make sure the gem does not
have any surface reaching inclusions or chips which would affect its
durability for daily wear.
color stones are cut to ensure the best potential color when facing
up. Sometimes a cutter has to cut the pavilion (bottom of the gem) to
unusual proportions in order to achieve the best possible color face
up. As long as the shape of the gemstone is not compromised, the actual
number of facets or placement of facets will not devalue a gemstone.
However, if most of the weight of the gem is found underneath the stone,
this will result in a smaller looking stone face up. This gives you
less value for the purchase price.
- In contrast, if the cut of the gem is too shallow, you might see a window
effect in the color gem. This window is an area of the gemstone where
the color is less saturated. The best way to evaluate the cut of your
color stone is to compare it to other gems in the same shape and weight
weight depends on the size you are looking for. As stated earlier, make
sure the stone is not cut so deep that you lose the look of the carat
weight. (The deeper cut the stone the smaller it will look face up).
such as "Burmese Ruby" or "Colombian Emerald" describe
the color characteristics of gems mined in those geographical areas rather
than the actual origin of a particular gemstone. Fine quality color stones
are found all over the world! Many gemstones possess similar color characteristics
of other gems found in different countries. Look for the color that appeals
is stated regarding the durability (hardness) of certain gems (i.e. Tanzanites
or Emeralds). However, understand that the most pressure a polished stone
endures is the setting process by a jeweler. If it is not damaged by this
process, chances are slim that it will be damaged during normal daily
wear. In addition, most color stone mountings created by Giraux Fine Jewelry
are designed to protect the gem as much as possible. Remember to always
insure your item(s). (See: 7 tips on keeping your jewelry in top shape)
are many gems that exist that do not make it to the consumer market. Apatite,
amblygonite, aragonite, phosphophylite, are just a few examples of gem
mineral species that are rare to none in their existence on the retail
market. This is because their Mohs Hardness ranges from 3-6 and thus deemed
not hard enough for daily wear. Remember, for a gem to be considered
valuable enough for jewelry use, it must be rare, durable, and beautiful.
all color stones are subjected to enhancement. Some are heat treated or
irradiated to enhance color, while others like emeralds are oiled to prevent
cracking. The treatment depends on the requirements of type of gem. Treatments
are often applied to enhance the color, or to strengthen the stone. Most
treatments are permanent and necessary to enhance value.
which are not permanent do not add value to the gemstone and are a mask
to hide imperfections. These treatments legally must be disclosed to the
