Altogether it is a simple gem but it is not simple to get hold of a genuine
gemstone. In order to make the purchase of a real amethyst buyer needs to be
familiar with the facts and other details about the stone. This content is
presented with the aim of providing all-purpose information that would
assist the buyer in knowing the gemstone fully. We would first start with
the four important Cs and then other characteristics.
Colour - This good-looking gemstone has to be purple in colour.
However, different shades of purple are found as it is procured from diverse
parts of the universe that have different climatic conditions, nature of the
chemical composition and temperature levels etc. With the shade of purple
colour of the stone, the country could be identified from where the
respective stone is acquired. Sometimes, in the chemical composition of the
stone few traces of iron are found due to which the colour of the stone
turns violet. Blue and gray are other colour possibilities. Colour other
than shades of purple is considered below quality standard therefore is
valued less.
Few dark purple colored stone produce red flash effect when swiveled under
any direct light source. With decrease in the depth of the purple colour the
value of the stone in terms of money also decreases. While buying the
gemstone, one should always opt stones having saturated distribution of
colour all over the surface.
Clarity - It is the gemstone with crystal clear appearance. It
gains an edge over other affordable semi precious gemstones due to its
transparency. By and large it is free from inclusions and flaws but there
always exists the prospect that few stones might have some defects. If the
stone is bright purple in colour then few minor inclusions can be neglected
and should be neglected as such defects seldom harms the beauty of the
stone. Overall it is a clean and clear stone.
Cut - Cutting is not very difficult for this stone, it can be
given varied shapes and sizes. These days many innovative shapes are seen
like that of a leaf, star and new moon etc. Some common cuts are pear, oval,
emerald, square, round and triangle etc. When the colour is spread evenly
throughout the stone the cutter could give any desired cut as demanded by
the jewelry designers and buyers. In case of uneven colour distribution
round cuts are the best to maximize the beauty and minimize the colour
defects. No matter what cut is given to the rough, the final stone must have
even facets and finely polished.
Carat Weight - This is an important price determinant. With the
increase in carat weight the price of the stone also increases. As this
stone is moderately priced, high carat weight stone can be selected. With
the larger stone the look of the jewelry items gets blown up that makes the
wearer center of attraction. The ideal weight for all the ornaments is more
than 2 carat. Moreover, almost all the designs cater to every size stones.
Stones with less than one ctw are not that effective in looks thus should be
preferred less.
Price - This startling semi precious gemstone is easily affordable
for the people having reasonable budgets. Price is ascertained on the basis
of all the four Cs that is colour, clarity, cut and carat weight. Bright
deep purple colour, crystal clear transparency, innovative cuts and high
carat weight are the zenith of all these four characteristics that fetches
high price. When the quality reduces from the zenith the cost also comes
down. One more important factor is rarity. Dark colored stone producing red
flash effect are very rare thus priced more.
Occurrence - It occurs as long prismatic crystals in the
metamorphic and igneous rocks consisting of coarse-grained silicon minerals.
Sometimes the composition might contain certain impurities that are
responsible for the colour change from purple to violet. The impurities are
nothing but the iron mineral present in the composition.
Source - It is found throughout the world hence is quite
affordable. Few countries to name are Brazil, Canada, India, Madagascar,
Australia, Argentina, Bolivia, Russia and Sri Lanka. Large stones consisting
of saturated colour all over the facade are obtained from different states
of United States of America like Colorado, Georgia, Montana, North Carolina,
Pennsylvania, Rhode Island and Virginia. Few African countries also produce
fair amount of this versatile gem that are Namibia, Uruguay and Zambia.
Enhancements - Dark shades are preferred over the lighter shades thus stone
with pale colours are heat treated or stained to improve the colour. The
treatments do not proffer the look as created by nature but it is
satisfactory and last for quite long. Enhanced stones are priced less over
the natural colours.
Imitations - It is easily created in laboratories through modern
methods and techniques. These synthetic stones are widely spread in the
gemstone market and sold under the fancy names like Japanese Amethyst,
Desert amethyst, False amethyst and Lithia amethyst. Poor quality purple
sapphire is treated and sold as Bengal amethyst. These imitations are very
much identical to the real gems therefore buyers should ensure the
reputations and truthfulness of the dealer before making the final purchase.
Use - It is widely used for making heart breaking jewelry item
viz. rings, necklaces, pendants, earrings, broaches and bracelets. This
gemstone jewelry could be worn for daily use. It gets very well paired with
diamonds and pearls. Sterling silver, 18K yellow gold and 14K or 18K white
gold are different metals used for jewelry making but for amethyst, yellow
gold is much better as it compliments the look of the stone. Females as well
as males love wearing rings holding this fine-looking gemstone. It makes
spectacular jewelries that are in demand in every corner of the globe.
Precautions - This astounding gem is rated 6.5 - 7.5 Mohs on the hardness
scale. The hardness rate implies it as a sturdy and firm stone. It does not
require any special care but too much exposure to the scorching sunlight
would ruin its beautiful colour. Sharp blows, scratches and hard hits
certainly splits the stone into two thus the wearer ought to be careful
while using it. Being slightly sensitive towards the heat it is prone to
damage under high temperature changes and excessive heat. It is recommended
to prevent the stone from such conditions.
It can be cleaned in home ultrasonic cleaner but still this method should
be avoided, as it is wiser to clean it with warm soapy water and soft
bristle toothbrush. Cleaning should be done only once in a while as regular
cleaning deteriorates the natural shine of the stone and its jewelry. It
should be stored in a fabric-lined jewelry box wrapped in cotton. These few
precautions offer longer life for this captivating gem.

marvelous gemstone mounted in their crowns and other jewelry pieces. It also

important part of the ornamentation of Catholic Church and is mentioned in
