Current Hallmarks
UK Hallmarking Act
Current hallmarking requirements come under
the UK Hallmarking Act 1973 and subsequent amendments. The Act is
built around the principle of description, where it is an offence
for any person to apply to an unhallmarked article a description indicating
that it is wholly or partly made of gold, silver or platinum. There
is an exemption by weight: compulsory hallmarks are not needed on
gold under 1g, silver under 7.78g and platinum under 0.5g. Also, some
descriptions are permissible, such as rolled gold and gold plate.
The four assay offices at London, Birmingham,
Sheffield
and Edinburgh
operate under the Act.
Breaches of the Act carry stiff sentences (up to 10 years' imprisonment).
The following are extracts from the above Act:
Dealers shall keep exhibited at all times, in a conspicuous
position in a part of their premises to which those with whom they
deal are commonly admitted, a notice in terms approved and in a form
supplied by the Council describing such approved hallmarks and including
such explanatory matter as the Council think fit; and it shall be
an offence for any dealer to fail to exhibit or keep exhibited a notice
required to be exhibited under this subsection.
‘Dealer’ means a person engaged in the business of making,
supplying, selling (including selling by auction) or exchanging articles
of precious metal or in other dealings in such articles.
THE STATUTORY NOTICE WHICH DEALERS ARE REQUIRED TO DISPLAY ON THEIR
PREMISES (DESCRIBING THE UK LEGAL HALLMARKS) IS REFERENCED DN2
The notice is sized 14¼ inches by 11 inches, permanently lacquer
finished and suitable for hanging or standing.
Cost: £10 each (including package, postage and VAT)

Minimum Legal Hallmark
Since 1999, a minimum hallmark comprises:
(i) A sponsor's mark (see Getting
Something Hallmarked: Sponsor's Mark)
(ii) A millesimal fineness mark. This is the number of parts
per thousand of pure metal in the alloy. The current finenesses allowed
in the UK are shown here.
(iii) An assay office mark

Convention Marks
The United Kingdom has been a signatory
to the International Convention on Hallmarks since 1972. This means
that UK Assay Offices can strike the Convention Hallmark which will
then be recognised by all member countries in the International Convention.
Conversely, Convention Hallmarks from other member countries are legally
recognised in the UK. Articles bearing the Convention Hallmarks do
not have to be re-hallmarked in the UK.

The Assay Office Marks of member countries
of the Convention are illustrated below. The shield design around
the Assay Office Mark sometimes varies according to whether the article
is gold, silver or platinum. The key mark to look for is the Common
Control Mark. The three other marks must also be present.

Not all UK finenesses are represented in
the convention but many are common and the CCM is often added to a
UK hallmark.

Guidelines to European National Hallmarks
Since 1st January 1999, following
a ruling of the European Court of Justice, the UK is required to accept
(and not re-hallmark) other European national hallmarks which provide
an equivalent guarantee to consumers. It is the opinion of the British
Hallmarking Council that such hallmarks must contain a Sponsor's or
Maker's Mark, a Fineness (Purity) Mark and an Assay Office Mark. For
example
 |
 |
 |
 |
 |
| Sponsor's or Maker's Mark,
a Fineness (Purity) Mark and an Assay Office Mark. |
|
 |
The complete Hallmark must guarantee that
the purity of the metal is at least that indicated by the Fineness
Number.
Some European national Hallmarks incorporate the Fineness (Purity)
Mark in the Assay Office Mark. For example:
 |
 |
 |
 |
 |
| Fineness (Purity) Mark in
the Assay Office Mark. |
|
 |
Using these criteria the national hallmarks
of Cyprus, Czech Republic, Denmark, Finland, Hungary, Ireland,
Netherlands, Portugal, Slovenia and Switzerland,
without the Common Control Mark, are acceptable in the UK.

is based on information available on 30 September 2004. It is subject
to change.
Some European hallmarking countries are not members of the International
Convention.
Spain has a dual system of Assay
Office hallmarking and licenced manufacturers' marking. The only Spanish
hallmarks which conform to the British Hallmarking Council criteria
are:
In the opinion of the British Hallmarking
Council, the national law of Belgium does not presently provide
an equivalent guarantee. Some European hallmarking countries are in
the process of amending national laws, in the light of the European
Court of Justice ruling. Consequently, the list of acceptable Assay
Office Marks is likely to be extended.
Italy, Germany, Greece and Luxembourg do not have independent
systems of guarantee. Articles from these countries must be hallmarked
in the UK or Convention hallmarked in one of the Convention countries.
National hallmarks of countries outside the European Economic Area
are not legal in the UK. Articles from these countries must
be hallmarked in the UK or Convention hallmarked in one of
the Convention countries.
