About this Valuer

GHM Jewellery Valuations is headed by Gaynor Haylett-Mustafa who has over 25 years experience in jewellery trade, having worked with some of the UK's most prestigious jewellers. GHM specialises in home-visit jewellery appraisals within the home counties of Cambridgeshire, Bedfordshire, Hertfordshire, and South Lincolnshire. Gaynor also works with retail jewellers in these ares to provide a swift valuation service to clients who prefer to work directly with their family jeweller.

Gaynor, who studied diamond grading at the International Gemological Institute in Antwerp and the Gem-A in London, invites enquiries from clients within 1.5 hours of St Neots. After establishing the scope of the appraisal assignment, you will be given an estimate of the valuation fee, the cost of your appraisal is calculated on a straight forward price per item basis. For your peace of mind, all grading of the diamonds and gemstones and the assessment of your jewellery will be carried out in your home or office. To minimise the disruption to your routine, all the research and report-writing is carried out off-site. The Valuer usually completes your documentation within a week, subject to the complexity and quantity of items examined.

GHM provides jewellery valuations for the purposes of Insurance Replacement, Probate, Division of Assets, Sale by Private Treaty, Open Market and Family Division. Jewellery of all types (antique, period and modern) are handled by this jewellery expert. Two bound reports are provided, one for your own records which includes quality photographs of your precious items, the other copy can be forwarded to your insurance company or solicitor.

Gaynor is very approachable and would be delighted to answer any questions about her service to you. Please contact her using the email and telephone links at the top of this page.
