Platinum
was originally used by European Court Jewellers in the mid
1800's. Before this time scientists were unable to isolate
the metal and produce it in it's pure form.
Until
the late 1800's it remained too expensive for commercial
use and only the wealthy could afford platinum settings.
Until the late Edwardian period, it's colour remained largely
out of favour for anything other than settings as yellow
gold was so fashionable. However by the early 1900's trends
were changing and the "new look" was being embraced.
It remained the metal of choice for those who could afford
it through the 20's and 30's until the effects of the War
made it far too costly to produce, and with demand for jewellery
falling it all but disappeared from jewellers windows for
several years.
There
was no legal requirement for marking Platinum until 1975,
which set a single standard for platinum of 950. Earlier
Platinum pieces may be stamped PLAT by the manufacturer.
