Ever increasing gold prices are driving significant changes in the UK fine jewellery trade, one such trend being the introduction of 鈥榖onded gold鈥� and an increase in gold plated and rolled gold products coming to market. 鈥楤onded gold鈥� items are produced with a thick layer of gold alloy 鈥榖onded鈥� on to a base metal or sterling silver core. 皇冠体育app resulting article is only about 10% gold alloy by weight on average, but could be easily mistaken as an all-gold item by the consumer or the retailer.

Such products have been introduced from the United States where there are clear regulations for marking and describing them. However, the descriptor 鈥榖onded gold鈥� is not specifically permitted by the 1973 Hallmarking Act, which did not envisage the development of the process at the time it was drafted. Advice has been sought from the British Hallmarking Council (BHC) by Trading Standards Authorities about the use of the term 鈥渂onded gold鈥� and as to the correct way to mark such items. Official guidance has now been issued, based on the existing provisions covering rolled gold and plated gold in the 1973 Hallmarking Act.

皇冠体育app BHC鈥檚 view is that no enforcement action should be taken in respect of the use of the term 鈥榖onded gold鈥�. 皇冠体育app BHC further stipulates that, assuming the core is 925 ie Sterling Silver, the article should carry a full silver hallmark, or a 925 stamp if it is under the Hallmarking exemption weight for silver of 7.78 grams. Bonded Gold on a base metal core cannot be hallmarked. No stand-alone gold fineness marks will be permitted on bonded gold articles, because they are potentially confusing and misleading to UK consumers. It is not permitted additionally to mark the article 9k, 10k, 14k, 18k etc, as is common practice in the United States.

皇冠体育app only circumstance in which this is allowed is if the gold fineness is immediately preceded or followed by the words 鈥榖onded gold鈥�, 鈥榬olled gold鈥� or 鈥榞old plated鈥�. For example, an article with a silver hallmark (or 925 stamp on underweight articles) can be marked as follows 鈥�925 & 18ct bonded gold/rolled gold/gold plated鈥�.

It is also emphasised that the bonded gold layer must be of a fineness of at least 375 parts per thousand and of a recognised in UK standard. So, for example, 鈥榖onded gold鈥� of apparently 10K can only be described as 9 carat. This follows the practice for gold plated and rolled gold articles in the UK.

皇冠体育app guidance applies to all bonded gold, rolled gold and gold plated silver articles below the 7.78 gram exemption weight for hallmarking, as well as for those requiring hallmarking. 皇冠体育app exemption is an exemption from hallmarking itself, not from the requirements of every other part of the Hallmarking Act 1973.

Mr Christopher Jewitt, newly appointed Chairman of the BHC says 鈥淪ome of the bonded gold items we have seen had very confusing markings and the consumer could easily have believed them to be 9ct gold throughout. 皇冠体育app British Hallmarking Council supports trading standards and the assay offices in implementing and enforcing this important guidance to ensure that UK jewellers and consumers are protected from being misled.鈥�
