In 1985, wholesale diamond prices were added to the publication, making it the most comprehensive pricing guide in the industry. The publication, which is recognized as the industry leader for gem pricing and market information, is used for valuation and information in more than 40 countries by jewellers, appraisers and as a reference in legal cases involving valuation.

Letters of transmittal, Rosamond Clayton


Rosamond's presentation discusses the importance of an accurate and professional covering letter when you submit your valuation schedule or post loss assessment. It further considers the need for certain information relating to their report, clarification of the terms you have used and why you have included them in the letter.

There is an opportunity here to build up a long term relationship with your client through speaking personally to them and going the ‘extra mile’ to help and advise them and making your client feel that you care.

Meet the Sponsor

Th March summit sponsorIn 1887 the eighteen-year-old son of a London Hatton Garden diamond merchant (our founder Tommy March) experienced a ‘eureka’ moment. He realised that the jewellery trade he’d come to know through his Father’s business, was largely uninsured. His idea blossomed to become the UK’s best known firm of jewellery trade specialist insurance brokers (“Famous for Insuring Jewellery”) TH March.
