Diamond Tiara :                        
The tiara was described by Leslie Field as "a diamond festoon-and-scroll design surmounted by nine large oriental pearls on diamond spikes and set on a bandeau base of alternate round and lozenge collets between two plain bands of diamonds". Queen Elizabeth II usually wears the tiara without the base or pearls.
A portrait of Queen Elizabeth II wearing the tiara, designed by Arnold Machin, has appeared on many Commonwealth currencies, including those of Britain, Australia, Jamaica, Canada and Ceylon.

Crowns :
The collection of Crown Jewels contains various crowns, some of which are used by every Sovereign, others being made personally for Sovereigns or for the Queens Consort. Typically the crown of a King has a slightly pointed arched top, while that of a Queen has a slightly bowed top.
