Precious Metal Marks
Precious metal marks, also known as hallmarks, are small etched or stamped impressions that indicate the purity of a metal object. They are typically found on jewellery, coins, bullion, and other metal objects, and often serve as a unique identifier for the item in question. While some countries may have their own system of hallmarks, most precious metal marks follow a few common standards.
Maker’s Mark and Assay Mark
Hallmarks are typically divided into two categories: maker’s marks and assay marks. A maker’s mark is a unique identifier that indicates the maker of the jewellery or metal object. It may be a logo or symbol, initials, or even a full name. Assay marks are used to indicate the purity of the metal. The mark will typically be a combination of letters and numbers that indicate the percentage of a metal, such as an “18K” mark for 18-karat gold.
Additionally, precious metal marks may include a date mark that indicates when the item was made. This is usually a combination of letters and numbers that indicate the year and sometimes the month. For example, a “crown” mark may indicate that the item was made in 1952.
Country of Origin
Hallmarks may also include a country mark that indicates where the item was made. This is typically a symbol that represents the country, such as a lion’s head for England or an eagle for the United States.
Finally, there may be a standard mark that indicates the quality of the metal. This mark will usually be a symbol, such as a star, which indicates the item is made from a certain standard of metal. For example, a star mark may indicate that the item is made of sterling silver.
Typical Precious Metal Marks Found on Jewellery
Jewellery is a timeless and precious item which is often adorned by people to highlight their sense of style and to express themselves. Jewellery is often made up of precious metals and stones such as gold, silver, diamonds, rubies, sapphires, emeralds, and more, each of which carries its own significance. Along with the precious materials used to create a piece of jewellery come a variety of marks that indicate the purity of the metals and the origin of the stones used. Knowing the different marks found on jewellery can help you to determine its value and authenticity.
Hallmarks are one of the most recognizable marks found on jewellery. These are the stamps used by jewellers to indicate the metal purity of a piece of jewellery. Common hallmarks used in gold jewellery are 8K, 9ct (375) 10K, 14K (585), 18ct (750) and 22ct (916), which indicate the purity of the gold used in the piece. Silver jewellery is typically marked with a ‘925’ or ‘sterling silver’ mark.
The maker’s mark is a stamped symbol or signature used by a jeweller or goldsmith to indicate the origin of the piece. This is commonly the jeweller’s name or initials and can help to identify the maker of the piece.
Gemstone marks are used to indicate the origin of the stone used in the jewellery. Diamonds are often marked with a ‘GIA’ or ‘AGS’ mark, which indicates that the stone has been certified by the Gemmological Institute of America or the American Gem Society. Rubies, sapphires, and emeralds are typically marked with the country of origin, such as ‘Burma’ for rubies or ‘Colombia’ for emeralds.
Assay marks are used to indicate that the metal used in the jewellery has been tested for purity and is of a certain quality. These marks are typically used in gold, silver and platinum jewellery and indicate that the metal has been tested and approved by a government approved assay office.
These are just a few of the marks found on jewellery that indicate its value and authenticity. Knowing these marks can help you to determine the quality and origin of the jewellery and can help you to make an informed purchase.
