This traditional English classic ring features a historical gold crown hallmark, a symbol that has been in use since1798. The crown mark is laser inscribed onto an gold octagon at the centre of the ring, revealing the true colour of 18K gold. Beneath the smooth exterior lie three further marks of distinction – the 700 years old, historical leopard's head, which is the mark of the London Assay Office, the England Diamond “ED” mark, confirming the company responsible for this ring, and the 750 mark, assuring the ring's 18k purity. The above 4 marks are all inscribed in London at the assay office, and the ring with these marks can be traced back at the office under the maker England Diamond Company Ltd, the recognized maker of quality rings that comply to the gold standard.
