'The extensive research in this outsize format along with the number and quality of photographs make these books collector’s items in their own right and one that no gem library will be without.

A fail-proof gift for jewellery and gem fans just in time for Christmas' - The Jewellery Editor, of 'Ruby', 'Emerald' and 'Sapphire'
