GOLD
The allure
of gold
From
the beginning of time, gold has been one of the most highly
valued and most sought after of the precious metals.
At various times
it has been accorded magical and mystical properties, has been
fought over, prized as a medium of exchange, has had the badge
of royalty and wealth and has lured people of all cultures to
vast unknown lands in quest of it.
Over centuries
of growing sophistication and technology, gold has assumed many
additional roles. Not only is it still prized for jewellery,
it also has many new applications in contemporary modern day
life.
Gold soared into
space with the astronauts, it's reflective ability used on the
heat shields that are crucial to life in space. This same ability
to reflect the sun increases the aesthetic and practical and
beauty of today's glass skyscrapers. The gold in tinted windows
makes the difference obstructive glare and glamorous gleam.
Among the many
other specific applications gold is used in telephones and telecommunications,
T.V.sets, computers and calculators. It also has important applications
in medicine and dentistry.
But, above all,
gold has enjoyed it's finest glitter through the ages in it's
ultimate form - jewellery. In fact, the wearing of gold for personal
adornment may actually be our oldest surviving tradition.
Every day, virtually
each one of us continues the centuries old ritual of gold adornment.
Men, women and children of all cultures are caught up in gold's
allure through the acquisition and wearing of any number of pieces
gold jewellery, whether it be a ring, chain, earrings, watch
or bracelet.
The uniqueness
of gold
Of all the world's precious metals, only gold combines the four
basic characteristic that makes it a universally and eternally
treasured possession - lustrous beauty, rarity, durability and
ease of workability:
Lustrous Beauty
- The naturally intense colour and distinctive lustre of gold
combine to give this precious metal it's unique and lasting beauty.
Gold's natural beauty is further enhanced by the soft and exquisite
shades of colour achieved by combining it small amounts of other
precious and base metals.
The many colours
of gold include, yellow, white, pink and green, and to a lesser
extent, shades of blue and purple. All are exquisite in their
own right. There is always fashion acceptance of all the colours,
and colour combinations of gold. A popular current trend in jewellery
is the combination of yellow, white and pink.
Rarity - Although
gold is everywhere around us - in the earth's crust, in our seas,
rivers and plants - the difficulty and expense of obtaining gold
from these sources makes recovery of any substantial amounts
unlikely. Where gold is found to exist, several tonnes of ore
may be required in order to extract just one ounce of this precious
metal.
This rarity alone
is enough to bestow a certain symbolism and status to gold, but
when combined with it's other inherent characteristics, this
lustrous and beautiful metal becomes an even more desirable possession.
Durability -
Gold virtually lasts forever. It does not tarnish or corrode.
An example of it's incredible durability is evidenced in the
gold coins found in centuries old sunken galleons. Each coin
is as bright and shiny as the day it was made. Another familiar
example which has overwhelmed millions of people are the treasures
of King Tut. When the boy King Tutankhamen died in 1350 B.C.
he was buried with vast quantities of gold artefacts and jewellery.
Today, more than 3,000 years later, viewers marvel at the breathtaking
array of items, as gleaming and lustrous today as they were buried
with the young king.
Today, when you
buy gold jewellery, you are buying enduring beauty, that reflects
the properties of this precious metal. A gift of gold has always
been the symbol of lasting love and devotion.
Ease of workability
- Gold has the best working qualities of any metal, thereby making
it the ideal precious metal for fine jewellery.
To give you an
ideas of it's workability, gold is so soft and malleable that
one ounce can be stretched into a wire an incredible 80 kilometres
long or hammered into a sheet so thin that it covers well over
9 square metres and becomes transparent. It is gold's workability
that enables it to be alloyed with other precious and base metals
to produce special qualities or to achieve variations of colour.
Gold can be remelted
and used again and again and it can be made into a vast array
of jewellery items. From the most intricate baby bracelet to
the heaviest chain gold's workability gives it the ability to
exist in a multitude of forms and shapes.
How do you
know it is real gold?
When purchasing
an item of jewellery, you should always look for a carat mark
which should be stamped on the item. The carat mark is a quality
mark and refers to the proportion of pure gold in the item. Pure
gold, which is 24ct, the metric equivalent being 1,000 is generally
considered too soft for practical use in jewellery and is alloyed
with other precious and base metals to increase it's durability
and workability.
Some of the common
markings found on jewellery (with their metric equivalents) are
as follows:
22ct or 916
18ct or 750
14ct or 585
9ct or 375
Some other precious metal markings you may find on jewellery are:
Silver - sterling or 925
Platinum - Plat, Pt or 950
Palladium - Pall, Pd or 900
Markings on jewellery
items are not limited to the carat or quality mark. You may find
a manufacturer's trade mark, logo or initials on some jewellery,
particularly items made in the United Kingdom where a comprehensive
hallmarking system is in place.
If you are in
doubt about the markings that appear on any piece of fine jewellery,
ask our jeweller next time you are in our store.
"I can't wear
gold .... it leaves a black mark".
Members
of the Jewellers Association of Australia often hear this complaint.
They call it "the mystery of the gold smudge".
Gold
under normal circumstances won't tarnish or corrode, but there
are generations
of old wives tales about "not being able to wear gold". Research
into "the gold smudge" has revealed 5 down to earth reasons why
gold can sometimes leave a black mark or rash.
- Sometimes
skin secretion and perspiration contains chemicals which react
with the molecules of other metals in the gold alloy. This
can happen when changes occur in the body chemistry, for example
during pregnancy.
- Outside
chemical influences, such as cosmetics, hairsprays and perfumes
may
sometimes be to blame for the "smudge" - always take care to
apply these products before you put on your jewellery.
- Air
pollutants from industry may also cause the "smudge" which
can rub off onto the skin when the jewellery is worn.
- Minute
particles of dust or powder may be imbedded in the skin which
can result
in extremely small particles of gold alloy being abraded and
deposited on the skin as a "black smudge".
- The fifth
and least likely cause may be an allergy to gold or one of
the other metals in the gold alloy. An example of this is an
allergy to nickel. Nickel is commonly used in fashion jewellery
and in some white golds.
