The shop was established in Amersham back in 1986 by David Warner and is run today by his son, Simon. After starting in the family business and learning the ropes, Simon went on to study diplomas in Gemology and Diamonds including Diamond Grading.The awards achieved in these fields from the British Gemological Association are recognised as being the most distinguished international gemological qualifications available in the trade. Here at D.J.Warner, Simon and his team believe that customer service is one of the most important factors of the retail trade. You will always be warmly welcomed here, and dealt with in the same way whether you require a new battery for your watch or a diamond engagement ring. The product awareness and honesty you will receive regarding a purchase or a valued repair comes from the many years of knowledge built up in the trade by Simon and his staff.
