| From
the first discoveries of gold in ancient times, its beauty and
the ease with which it could be worked inspired craftsmen to
create it into ornaments, not just for adornment, but as symbols
of wealth and power. The skills of the goldsmith from ancient
Egypt to Benvenuto Cellini or Carl Faberge still amaze us. As
Pihder wrote nearly 2,500 years ago, "Gold is the child
of Zeus, neither moth nor rust devoureth it". Today, gold
jewellery is more a mass- market product, although in many countries
still treasured as a basic form of saving. jewellery fabrication
is the crucial cornerstone of the gold market, annually consuming
all gold that is newly mined.
Pure gold is used in those parts of the world
where jewellery is purchased as much for in- vestment as it
is for adornment, but it tends to be vulnerable to scratching.
Elsewhere, it is usually mixed, or alloyed, with other metals.
Not only do they harden it, but influence the colour; white
shades are achieved by alloying gold with silver, nickel or
palladium; red alloys contain mainly copper. A harder alloy
is made by adding nickel or a tiny percentage of titanium.
The proportion of gold in jewellery is measured
on the carat (or karat) scale. The word carat comes from the
carob seed, which was originally used to balance scales in Oriental
bazaars. Pure gold is designated 24 carat, which compares with
the "fineness" by which bar gold is defined. |

most widely used alloys for jewellery in Europe are 18 and 14
carat, although 9 carat is popular in Britain. Portugal has
a unique designation of 19.2 carats. In the United States 14
carat predominates, with some 10 carat. In the Middle East,
India and South East Asia, jewellery is traditionally 22 carat
(sometimes even 23 carat). In China, Hong Kong and some other
parts of Asia, "chuk kam" or pure gold jewellery of
990 fineness (almost 24 carat) is popular.
In many countries the law requires that every
item of gold jewellery is clearly stamped with its caratage.
This is often controlled through hallmarking, a system which
originated in London at Goldsmiths' Hall in the 14th century.
Today it is compulsory in such countries as Britain, France,
the Netherlands, Morocco, Egypt, and Bahrain. Where there is
no compulsory marking manufacturers themselves usually stamp
the jewellery both with their own individual identifying mark
and the caratage or fineness.
The European Commission wants to introduce
a common system for guaranteeing standards of fineness within
member countries of the European Community. Three strictly supervised
systems are possible; either I) Hall- marking, 2) Quality control,
according to the European norm on quality (EN 29000), or 3)
Certificate of conformity by manufacturers, control- led by
an independent third party.
Until recently the earliest known gold jewellery
was believed to date from the Sumer civilisation, which inhabited
what is now southern Iraq around 3000 BC. Recent discoveries
suggest however that goldsmithing first began on the shores
of the Black Sea, in the land that is today Bulgaria (for more

of Montréal http://www.pacmusee.qc.ca/an/expos/varna/histoire.html.
Articles displaying various techniques such as repousse, chain-
making, alloying and casting have been found in ancient Egyptian
tombs, with the best known examples coming from the treasures
of King Tutankhamun who died in 1352 BC. The Minoans on Crete
produced the first known cable chain, still very popular today,
and the Etruscans in Italy had developed granulation, whereby
items are decorated with tiny granules of gold, by the 7th century
BC.
Italy has remained
at the forefront of the gold jewellery industry. The Italian
Renaissance coincided with the discoveries of the New World
sources of gold, and wealthy Italian patrons encouraged goldsmiths
as they did painters and sculptors. The Spanish acquisition
of South American gold, however, was achieved at the expense
of the ancient heritage of Pre-Columbian goldsmiths. These craftsmen
were producing exquisite items as early as 1200 BC and their
art reached its zenith during the Chimu civilisation from the
12th to the I5th centuries AD, halted only by the mass looting
and slaughter by the "conquistadors".
Historically, gold was a rare metal, afforded
only by the wealthy. But the gold rushes to California and Australia
in the mid- 19th century ushered in a new dimension of gold
supply. They coincided, too, with the development of machinery
for making chain and other articles and of a much wider consumer
market. In the 20th century gold jewellery has come within the
pocket of most people.
The way ahead was pointed by Italy, which
has become jewellery manufacturer to the world, using over 400
tonnes of gold annually, more than two- thirds of it for export.
Factories often housing several hundred ma- chines that "knit"
gold wire into chain flourish in the towns of Arezzo, Bassano
del Grappa and Vicenza.
Important new centres emerged in the early 1990s, notably in
Hong Kong, Singapore, Malaysia and Thailand, catering
particularly for the rapidly growing market for chukka am (pure
gold) jewellery in China, which requires several hundred tonnes
a year. In Japan jewellery fabrication for the domestic market
has become a major industry, using around 100 tonnes a year.
Attitudes to jewellery still vary. In the
industrial countries gold jewellery is primarily a fashion item.
But in the Middle East and much of Asia gold ornaments are seen
equally as investment; 22 carat articles are bought on a low
mark-up of only 10-20 per cent over the gold price of the day,
and may be traded in at a profit if the price rises or, more
often, for new articles.
The importance of jewellery to the gold mining
industry cannot be under-estimated. Between 1970 and 1992 around
65 per cent of all gold available to the market was used in
jewellery, and from the late 1980's into the 1990's, it absorbed
much of the rise in production. Since 1991 over 2,000 tonnes
of gold has been used annually. The continuing success of the
mining industry is inextricably linked with the fortunes of
the jewellery trade.
