David P. Stern Hallmarking
Hallmarking was originally introduced in 1300 by a Statute of Edward I and is one of the earliest forms of consumer protection.Hallmarking is necessary because when jewellery and silverware are manufactured, precious metals are not used in their pure form, as they are too soft. Gold, Silver, and Platinum are always alloyed with copper or other metals to create an alloy that is more suitable to the requirements of the jeweller. Such an alloy needs to be strong, workable, yet still attractive.
Owing to the high value of gold, platinum and silver, there are significant profits to be gained by reducing the precious metal content of an alloy at the manufacturing stage. Base metal articles plated with a thin coat of gold or silver look the same as articles made wholly of precious metal, at least until the plating wears, and even an expert cannot determine the quality or standard of precious metal items by eye or touch alone.
With volume manufacturing, enormous profits can be made from even a small reduction in the amount of precious metal used. Without compulsory independent testing there is huge potential for deception and fraud.
The UK Hallmarking system has offered valuable protection for over 700 years. Compulsory Hallmarking protects all parties; the public who receive a guarantee of quality, the manufacturer who is given quality control and protection from dishonest competitors at a very low cost, and the retailer who avoids the near impossible task of checking standards on all his goods.
