Mr James Barringer of London said: "I was looking for a unique engagement ring and nothing I had seen in the shops fitted my requirements. With my very limited experience of jewellery, Mark's frank and expert knowledge was invaluable in designing the most beautiful piece. Following my initial input he patiently guided me through all of the options and with frequent consultation created several designs for me to choose from. The whole process was seamless and the end result is simply stunning."
