Pre-Columbian South American Indians are known to
have found ways to use platinum for decorative purposes.
The first known example of platinum goes back to
prehistoric times in South America - where a small head statue
is known to have been shaped out of the metal. Awareness in Europe
dates back to 1557 to a French-Italian scientist Julius Scaliger
who was in Central America when large deposits of the metal were
discovered in South America by the Conquistadors. It's from this
discovery that platinum got its name, from platina - the Spanish
word for "little silver".
However, it was not until samples began arriving
in Europe in the middle of the 18th Century, that processes to
melt and refine platinum were applied. In 1801, English physician
William Hyde Wollaston obtained the first pure sample and his methods
still form the basis of the techniques which produce platinum today.
Wollaston's discovery was an immediate commercial
success and he and his collaborators went on to isolate other platinum
group metals (PGMs). In 1824, the Ural Mountains were found to
harbour significant platinum deposits and by the end of the 19th
Century, a new jewellery style had developed combining the "new" metal
with diamonds from recently discovered mines in South Africa.
In 1924 South Africa became a rich source of platinum
itself when German geologist Hans Merensky discovered there the
largest deposits ever found.
The Second World War brought great restrictions on
the use of platinum as it was needed in armaments and it wasn't
until late in the 20th Century that its popularity as a choice
for jewellery returned. |
