The form, size and color of a number of these diamonds are recorded in models which are displayed in Higinbotham Hall of the Museum. This leaflet is devoted to a brief history and description of these. It may be remarked in advance that much that is legendary is contained in the accounts of the older diamonds, and it can hardly be deemed possible always to separate the traditional from the true. In such cases the would-be historian can do little more than to record some of the dfferent legends.
