Know Everything About How to Identify Natural Gemstones
appeal, magic and mystery have lured mankind since ages. Different
cultures across the world have lore and beliefs associated to colored
gemstones. In this day and age, natural gemstones are more of a
fashion accessory, though the mystical symbolism remains.
What are natural gemstones
A gemstone is
defined as a mineral or petrified material that when cut and
polished, can be used in jewelry. It is a mineral that is valuable,
rare and often beautiful.
forged beneath the surface of the earth over millions of years
through the forces of heat and pressure, resulting in a distinct
crystal form with an orderly pattern of atoms. This internal
arrangement determines a minerals chemical and physical
properties, including its color. Crystals are not necessarily formed
only in rocks or beneath the surface of the earth; they are also
formed within plants and animals. Such gemstones are called Organic
gemstones (coral, amber etc.). Every mineral originates as a small
crystal and grows as more atoms are added. A particular
gem or mineral can be a variety of different colors, depending on
impurities, also known as inclusions, in its atomic structure.
Quartz, for example, is normally colorless, but occurs in a range of
colors from pink to brown to the deep purple of amethyst, depending
on the amount and type of impurities in its structure.
precious because the extreme climatic conditions and the nurturing
inside earths womb for millions of years, are not just rare
conditions but almost impossible to occur again. And this is the
reason that the importance of gemstones is much beyond the obvious
4,000 different types of minerals found on earth, fewer than 100 are
considered beauteous or durable enough to be used as gemstones. Of
those, only around 20 are commonly used in jewelry. The traditionally
included category of most valuable gemstones is emerald,
and pearl. Because of
their aesthetic appeal and glorious history, these gemstones
are more valuable than other colored gemstones. Finest quality
emeralds and rubies can sometimes be more valuable than diamonds of
classified into different varieties, species and groups. For
instance, ruby (gemstone) is the red variety of the species corundum
(mineral) that belongs to the hematite (crystal) group. Varieties of
the mineral beryl include emerald (green), aquamarine (blue),
heliodor (yellow), bixbite (red), goshenite (colorless) and morganite (pink).
treatments or enhancements refer to the way some gems are treated to
improve their aesthetic appeal or durability, or even change their
color. Almost all gemstones are treated in some or the other way.
Most of these treatments are permanent in nature and an accepted norm
in the industry. Treatments do not affect a gemstones value.
gemstones are judged by the "Four Cs" of color, clarity,
cut and carat weight, with color being the most important
consideration, by far. As a general rule for all gemstones, the
better the color, the higher the value; better clarity and better cut
are also valued more - and generally, the larger the stone, the more
it will cost per carat. Even to an untrained novice eye, many of
these types of differences can be seen when similar stones are
that may influence the price of a gemstone include whether it is
available readily or is rare in existence; whether it is a rare fancy
shape or a calibrated size; and sometimes the origin of the gem. For
from Kashmir or rubies
from Burma command a higher price than their equivalents from other origins.
