Gemstone Color |
|
The Glittering color of a gemstone is
its most defining characteristic, and many jewelers consider
it to be the most important evaluation criterion. When
deciding upon gemstone color, examine hue, tone, and
saturation.
Hue
The most valuable gemstones are those that exhibit a pure
color and only "slight" hues of other colors in addition to
their primary color, as all Divas gemstones do. For
example, Divas sapphires range in hue from "slightly
purplish-blue" to "slightly greenish-blue," pink sapphires
always range from "pink" to "slightly purplish-pink," and
rubies range from "slightly orangish-red" to "slightly
purplish-red". With the exception of opals, variation in a
gemstone's hue will be called out in the gemstone details on
the product detail page.
Tone
Tone represents the depth of color, ranging from colorless
to black. Gemstone tone is described as "light,"
"medium-light," "medium," "medium-dark," and "dark."
Divas offers gemstones with the most sought-after tones that
fall within the medium-light to medium-dark range. For all
of our gemstone jewelry, you'll find any tone variations are
called out in the gemstone details.
Saturation
Saturation, or color purity, refers to the degree to which
the gem is free from brown or gray hues. The most desirable
gemstones, which show little gray or brown, are often
described as having "vivid" or "strong" color saturation.
Generally, the levels of color saturation will not be called
out in the product details because the gemstones in our
jewelry are hand-selected for their vivid colors. |

Identifying Marks
Because gemstones form under unique circumstances,
each individual gemstone is comprised of a combination of
trace minerals, which create a unique set of identifying
marks or inclusions. Inclusions will not necessarily
detract from the beauty or desirability of a colored
gemstone. |
|
What to Look for
When considering a colored gemstone's clarity, you should
measure your expectations against the standard for that
variety of gemstone. Some varieties of colored gemstones,
such as aquamarine, blue topaz, and citrine, have
naturally fewer inclusions while other gemstones, such as
emerald and ruby, tend to have a higher rate of acceptable
inclusions.
Clarity is an important factor in comparing quality
colored gemstones. Even opaque opals can have milky
inclusions that will effect their iridescence and color
play. In general, the best values are available in
gemstones that are moderately included. Exceptional
gemstones with few or no inclusions are available, but
they can command extravagant prices.

Gemstone Cut |
|
Colored gemstones are generally cut
to maximize the beauty of their color. To recognize
quality in the cut of a gemstone, there are several points
to consider. |
|
what to Look For
A good cut showcases the gemstone's color, diminishes its
inclusions, and exhibits good overall symmetry and
proportion. Because gemstone color can vary, there are no
hard geometrical standards when it comes to maximizing
brilliance or color. Gemstones, especially rarer ones, are
sometimes cut for size without regard for their color. For
example, when corundum varieties such as sapphire and ruby
are cut for maximum weight rather than beauty, they may
display banded colors or streaks. Divas Dzire sells only the
finest quality, hand-selected colored gemstones.

Customer tips
In
a gemstone with more saturated color, the best cut may be
more shallow than average, permitting more light to
penetrate the gemstone, while in a less saturated gem, the
color may benefit from a deeper cut.
|
|
Gemstone Cut
Look at the gemstone in the setting and ensure that all
the facets are symmetrical. An asymmetrically-cut crown
indicates a gemstone of low-quality. In all cases, a
well-cut gemstone is symmetrical and reflects light evenly
across the surface, and the polish is smooth, without any
nicks or scratches. These are the characteristics that
Divas Dzire look for when selecting our gemstone
jewelry. |
|
Buyer Tips
Like
diamonds, fine quality color gems usually have a table,
crown, girdle, pavilion, and culet. Iridescent opals are
one exception, and most often have a rounded cabochon cut. |

|
Gemstone Size |
|
The carat weight of a gemstone does
not necessarily allow you to accurately envision the size
of the gemstone. Different gemstones have different
densities (mass per unit volume), so two gems that appear
to be the same size may actually have very different
weights. For example, a ruby is more dense than a diamond,
so a 1-carat ruby will look smaller than a 1-carat
diamond. |
Always
request the dimensions of a gemstone to ensure that the
majority of the gemstone weight will be visible when set
in the setting. |
| |
|
Gemstone Enhancements |
|
Unpolished gemstones are typically
very rough. Looking at gemstones straight from the mine,
they might be mistaken for pebbles or gravel. |
|
Almost every colored gemstone you
will come across has been heat-treated. It is a common
practice around the globe and has been going on for
centuries. Heating completes a process nature started, and
is used to enhance the colors of a gemstone.
The jewelry industry recognizes heating as acceptable and
expected processes. Heating is part of the standard
polishing and finishing process for many gemstone
varieties. The heating of gemstones is a practice accepted
by the jewelry industry, the American Gem Trade
Association (AGTA), and by Divas Dzire.

Buyers tips
Nearly all gemstones available on the open market have
been enhanced. Those that have not been enhanced are very
rare and command extravagant prices. Before buying a
gemstone that has not been enhanced ask to see a grading
report, preferably one from a well-known gemstone grading
lab (like the AGTA). The grading report should state that
the gem shows no indication of enhancement by heat. |

Gemstone Care |
|
After removing your gemstone
jewelry, wipe it with a soft cloth to remove dirt and
other residues.
In general, all you need to clean your gemstones is warm,
soapy water and a very soft brush-a soft toothbrush and
mild dishwashing liquid does a good job. Remove your
jewelry, let it soak in the soapy water for about 20
minutes, and then gently brush it and rinse thoroughly. Be
careful not to scratch the metal of your setting.
Home ultrasonic cleaners are not recommended for all of
your colored gemstones. Ruby and sapphire are typically
safe to clean in an ultrasonic cleaner but other gemstones
are not. Because of their porous composition, opals should
never be cleaned in an ultrasonic cleaner. Similarly,
emeralds should always be cleaned by hand. |

Store Gemstone
Jewelry
Store your gemstone jewelry in a lined case or a soft
cloth, so the gems do not touch each other or parts of
other jewelry. Gemstones are harder than gold, silver, or
platinum and can scratch the surfaces of your other fine
jewelry if they are not kept separate. |
|
Gemstone Jewelry wearing
While it's true that gemstones such as ruby and sapphire
are second only to diamond on the hardness scale, it is
not a measurement of their indestructibility. It means
that these gemstones are able to resist scratching almost
as well as diamond. Abrasive surfaces, harsh chemicals,
and sharp blows can damage even the toughest gem. Your
gemstone jewelry should be the last thing you put on when
getting dressed and the first thing you take off at the
end of the night. Store it carefully and it will be
enjoyed for generations. |
