Platinum producer Lonmin has opened entries for its annual Lonmin Design Innovation Awards for platinum jewellery.

UK platinum jewellery designers, whether independent or working for a retailer, have submitted their attempts, in the form of a drawing.

The competition is split into two categories, with four prizes for those with more than five years experience in platinum jewellery design and another four for those with less than five years.

Last year's competition was judged by renowned designer Stephen Webster, Albert Jamieson from Lonmin, Lesley Craze of Lesley Craze Gallery and Ruth Donaldson from Platinum Guild International, among many others from the platinum jewellery industry.

Its eight winners included Alexa Blampied, John Bradley, Tom Rucker and Janet Weller.
