Gemstones
Color
Jewelers describe the
color of a gemstone in terms of three characteristics: hue, saturation, and
tone. A gemstone's basic color is its hue, and those with purer hues (for
emeralds, green; for sapphires, blue; and for rubies, red) are generally
considered more valuable. Often, however, a hint of another color can be
detected. Saturation is a measure of the intensity or purity of a gem's hue and
is determined by the degree to which gray or brown hues mute its defining
color. Value tends to increase with saturation, so a fully saturated purplish
blue sapphire may well be more expensive than a muted pure blue one. The tone
of a gemstone, a measurement of its lightness or darkness, is usually given as
light, medium-light, medium, medium-dark, or dark.
Clarity
A flawless gemstone is
rare and expensive. As with diamonds, most gemstones have inclusions, or tiny
mineral flaws, that can be seen under magnification or by the careful eye. Make
sure that any inclusions in the stone do not penetrate deeply into the gem, as
this may cause it to break or crack. Clarity grades range from VVS (very, very
slightly included) to I3, in which inclusions are prominent and severely affect
the gemstone's beauty.
Cut
A gemstone's cut
refers to its proportions and symmetry. In making a gemstone look
appealing--the stone should be symmetrical in all dimensions so that it will
appear balanced, and that its facets will reflect light evenly. Color should
also be taken into account when cutting for optical efficiency. If a stone's
color is highly saturated, a shallow cut will allow it to pass more light,
while a deeper cut may increase the vividness of a less saturated gem. There is
no generally accepted grading system for gemstone cut.
Size
Though a gemstone's
weight is usually given in carats, this may not give an accurate idea of its
size, because different types of stone have different densities. Therefore, a
one-carat sapphire or ruby will be smaller than a one-carat emerald, though
they have the same weight, because sapphires and rubies (both a form of the
mineral corundum) are more dense than emeralds.
Gemstones can also be
measured in dimensions (diameter, length, and width). It is important to know
the dimensions to ensure that the gemstone weight will be visible and
well-proportioned in the setting.
Gemstone Treatment
Gemstones are often
treated to enhance color and fill cracks. Please note: if a gemstone has been
treated, this information will be provided in the specifications on the stone's
product detail page.
There are various
accepted techniques, depending on the type of stone:
Oils and resins are frequently used to fill surface-reaching
fissures in emeralds and rubies. This process is not permanent; however, if a
treated ruby or emerald is subjected to high heat, the filler may leak out of
the stone.
Sapphires and rubies are often heated in a kiln or furnace to
enhance their color. Such heat treatment, which is considered permanent, has
been used for centuries.
Lightly colored sapphires may also undergo diffusion treatment.
This is done by heating a stone in the presence of coloring elements such as
titanium or iron, which causes a thin layer of color to be diffused into the
stone's surface. Because this color layer is so thin, a diffusion-treated
sapphire should not be re-polished.
Gemstone Care
To clean gemstone
jewelry, first wipe it with a soft cloth to remove any dirt. Emeralds require
only the use of a soft cloth, as cleaners may damage these soft gems. Sapphires
and rubies can be cleaned with either an ultrasonic cleaner or a solution of
one part ammonia to six parts water, with a soft brush. Store your gemstone
jewelry in a soft cloth pouch or jewelry case so it does not touch other pieces
in your collection. As with all jewelry, normal wear and tear can loosen prongs
and settings, so it is a good idea to have it checked by a professional jeweler
who can make repairs as needed.
