HALLMARKINGINFORMATIONS
For the manufacture of jewellery and silver-
ware, precious metals are not used in their
purest forms. Instead they are alloyed with
other metals. It is not possible to discern by
sight or by touch what the precious metal
content of an alloy is.
Our customer can rest assured that all our
products come with a guarantee of the precious
content through the 700-year-old practice of
third party independent hallmarking.
The 1973 Hallmarking Act makes it unlawful to
describle an item over a certain weight as Gold,
Silver, Platinum or Palladium without an inde-
pendently applied Hallmark.
All Silver articles weighing more than 7.78
grams must be hallmarked.
All Gold articles weighing more than 1 gram
must be hallmarked.
All Platinum articles weighing more than
0.5 grams must be hallmarked.
All Palladium articles weighing more than
1 gram must be hallmarked.
Articles below this exemption weights may be
described as Gold, Silver, Palladium or Platinum
without the need for hallmark.
