What is Hallmark?
A hallmark on jewelry is an official mark or series of marks stamped on items made of metal, primarily to certify the content of precious metals, such as platinum, gold, silver, or palladium. It guarantees the purity of the metal, ensuring the piece meets legal standards and quality.
Essentially, a hallmark acts as a seal of approval from a trusted authority such as the Assay Office, that the jewelry you're buying is as valuable as it claims to be.
What is Assay Office?
The Assay Office is a hallmarking authority that basically controls and tests the jewelry. It also applies different hallmarks to the pieces, for example, the Purity mark 925. This mark indicates the precious metal content of the article and it means that it is composed of 92.5% silver and 7.5% other metals, usually copper.
How are precious metals controlled?
Precious metals are controlled through a process known as hallmarking. This is a form of government regulation and consumer protection where items made of precious metals are tested for content and purity.
The process usually involves:
Assaying: This is a method used to measure the purity of the precious metal. It usually involves analyzing the metal in a laboratory to determine the precise percentage of gold, silver, platinum, or palladium in the item.
Hallmarking: If the item passes the assaying process and meets the necessary standards, it is then hallmarked.
What kinds of jewelry are hallmarked?
Jewelry manufactured in countries of the European Union, and jewelry imported from other countries to EU, must first be marked with a responsibility mark, and then submitted for control to the Assay Office, which marks them with a state hallmark. The specific requirements for hallmarking can vary based on the laws of each country.
What is a Responsibility Mark?
The responsibility mark also called sponsor’s mark is assigned to each registered company or goldsmith by the relevant Assay Office. The responsibility mark demonstrates who is responsible for the precious metal content of the item. It is also part of a hallmark and it's registered with hallmarking authorities such as the Assay office.
What is The Common Control Mark (CCM)?
The Common Control Mark (CCM) is an international hallmark used under the Hallmarking Convention. It certifies that precious metal articles (such as gold, silver, platinum, and palladium) have been independently verified to meet the purity standards agreed upon by member countries of the Convention.
If an item carries the CCM mark and meets purity standards, it can be sold in member countries without further checks. The CCM, recognized internationally, simplifies trading quality precious metal items across borders.
What is The Hallmarking Convention?
Also known as the "Precious Metals Convention" is an international agreement established to standardize hallmarking for precious metals across member countries. It allows for the mutual recognition of hallmarks, ensuring that items like gold, silver, platinum, and palladium meet the purity standards.
This simplifies international trade by eliminating the need for re-testing and re-marking precious metal items when they move between countries.
It was signed in Vienna in November 1972 and entered into force in 1975. There are currently 22 Contracting States, which are parties to the Convention.
