Temporary hours: Monday – Closed Tuesday – Friday Close Book. The importance of verifying that something is what it claims to be has always been an issue in the trade of jewellery and precious wares. In part this is because gold, silver and even platinum are not generally used in their pure form to create jewellery or wares. The reason for this is due to both the price of making something in pure precious metal and also the relative softness of using pure precious metal whether it be gold, silver or even platinum. Other metals are added in order to make something more workable, harder or even to add a different colour, for example the “rose” in rose gold is due to the copper it is alloyed with. The fact is that by simply looking at an object one cannot assess whether a less expensive alloying metal has been used, whether an item is simply plated, or what the quantities of precious metal are. There have always been fraudsters or dishonest people who have sought to take advantage of this fact in order to misrepresent an object in order to get a better price. For this reason hallmarking is of vital importance and we are lucky today to have sound peace of mind that what we are buying is in fact what we are being sold; and this is due to the development of the hallmarking process. In the Middle Ages the industry was self-regulating and crafts were usually controlled by craft guilds.
