The hallmark "9.37.5" on gold indicates that the gold is 9 karats, which means it contains 37.5% pure gold and 62.5% other metals. This hallmark is commonly used in the UK and signifies that the piece has been tested and meets the required standards for that level of gold purity. In terms of quality, 9 karat gold is considered lower than higher karat options like 14k or 18k, which contain more gold content.
