The Jewels of the Craft Study and Collectors’ Circle was founded during the summer of 1990 to promote an interest in the study and collecting of Masonic jewels from all Masonic orders and to promote a wider Masonic knowledge through The Diadem - the quarterly magazine distributed to members of the Circle. The first issue of The Diadem was published during the autumn of 1990. The magazine, with 32 pages in A5 format, includes 8 pages of colour illustrations and is a useful reference source about Masonic jewels and their makers.

A number of regular features are included in The Diadem such as the study of Stewards Jewels issued at the Annual Festivals of the three Charitable Institutions for well over a century now – together with the 19^th century Favours that preceded them. Another feature is based on pre-regulation Centenary Jewels issued to Lodges prior to 1867. Members also contribute articles about Jewels associated with their own Lodge or Province – or collecting themes in which they are interested. There is also a section for Members’ queries – many of which are answered using the wealth of experience and knowledge available from the members of the Circle.

The Diadem is a magazine produced by the members for the members. Everyone is encouraged to participate by submitting articles about Masonic jewels and associated memorabilia for publication. Members are also involved in a considerable amount of original research – including the compilation of a directory of Masonic Jewel makers extending over nearly two centuries.
