The most expensive perfume is the Clive Christian No.1 for Men or No.1 for Women - 30 ml (1 fl oz) of which typically costs £1,317 (then $2,355). In November 2005, Clive Christian created 'No.1 Imperial Majesty' a 10-bottle, limited edition of the Clive Christian No 1 Collection, priced at £115,000 (then $205,000) per 500 ml (17 fl oz).

The perfume was presented in a Baccarat crystal flacon, decorated with a five-carat white diamond and an 18-carat gold collar. It was launched at the Roja Dove Haute Parfumerie in Harrods, London, UK and sold over Christmas both there and at Bergdorf Goodman in New York, USA. The price included delivery in a Bentley.
