Mark Nixon Jewellery Consulting offers a complete appraisal, valuing & advisory service for all jewellery. We are a truly independent company and have no ties or loyalties to any retail jewellers. We have expert appraisers on staff headed by Mark Nixon. We also have a broad panel of experts in all areas of jewellery, diamonds & coloured stones who can give experienced & informed advice on more unusual items.
Mainly used for insurance purposes (or you may just be curious as to what your jewellery is worth). All Appraisals are presented on a professional document which incorporates everything required to accurately identify and quantify a piece of jewellery. Appraisals include a full description, size estimates and quality assessment of diamonds & coloured stones, carat assessment of gold, quality of manufacture, the value (for the agreed purpose & function) and a macro (close-up) colour photograph of the item.

For unmounted diamonds. Very useful if you have bought or are thinking of buying a diamond to be mounted in a piece of jewellery at a later date. These documents give detailed information about the diamond and include accurate dimensions, style of cut, quality of cutting - which is known as “make” (including information about faceting, proportions, percentages and an overall make grade), a colour grade, a clarity grade, the weight of the diamond in carats, the value (for the agreed purpose & function) and a photograph of the diamond.
