The Platinum pattern mutation occurred in the UK in 1991. The coat pattern dilutes the ivory belly to almost white and the colouring of the back and sides becomes sprinkled with white hairs. The amount of white which appears in the coat can vary greatly with some Platinums having a fine sprinkling of white in the coat and others having so many white hairs that the colour is hardly visible although the dorsal stripe usually remains visible and the side arches retain colour.

The Platinum can be combined with any colour and coat type to produce for example, Argente Platinum, Black Platinum Satin, etc.
