A semi-precious
gem stone is considered a piece of mineral used to make jewellery and ornaments
after going through its cutting and polishing state. Several other rocks can
also be used to make these adornments such as lapis lazuli and several other
organic materials like amber. Gemstones are generally hard so some soft
minerals are incorporated during the jewellery making processes due to their
aesthetic look and lustre. Another characteristic feature of a real gem stones
is its rarity which adds to the value of gemstones
Characteristics and Classification of Gemstones
The ancient Greeks started the
traditional classification with differentiation between precious and
semi-precious. Today, modern usage considers precious stones to include
diamond, ruby sapphire and emerald, counting all other gemstones in the
category of semi-precious. These
distinctions are based on the rarity and quality with their translucent
appearance and fine colour (not inclusive of the colourless diamonds of the
different stones back in the day. Classifications of other r stones are also
done by colour, their translucent look and form (hardness). Gems are generally
identified by gemmologists who adopt the technical terminology to describe and
characterise gems. Firstly, a gemmologist characterises a gemstone using its
chemical composition. Typical examples
are with diamonds which are made of carbon and rubies which are made of
aluminium oxide. More so, many gems are classified using the crystal
system. Examples of crystal forms some
of these gems can have are cubic, monoclinic and trigonal. Gemstones are also
classified by habit which is usually the form in which the gem is found in. Diamonds
for example have the cubic crystal system, and in terms of habit, they are
found as octahedrons. Other ways to classify gemstones are in groups, species
and varieties. A typical example is ruby which is a red variety of the corundum
species. Other colours in the same species of Corundum are considered as
sapphire. Another example is given with Emerald which is the green variety of
the species aquamarine. Another form of classification of gems is in terms of
their water look, which in a broader concept is in terms of their brilliance,
transparency and /or lustre.
In terms of the value of gemstones,
there is no grading system that is universally accepted. Diamonds for example
are graded through a system formed by Gemmological Institute of America (GIA)
which was in the early 1950s. in those days, gemstones were graded using the
eyes. The colour of a gemstone, its
clarity, cut and carats are used today to grade any gemstone, to help the
consumer.
Colour and clarity remain some of the
important characteristics that make gemstones valuable. Emerald for example has
a number of cuts and uneven colour distribution and attractive star effects,
one of the characteristics Greeks look out for in gemstones which they consider
powerful love charms. It is also believed that Helen of Troy wore this
particular corundum.
