The pieces from the collection Petra represent fragments of rocks inspired by the mountains of the Dolomites, in Italy . This collection is pervaded by the call to nature and this is emphasised by the realisation process which is „honest and direct“: the wax models used for the casting were realised combining pieces of real rocks with pieces of wax and modelled using only the saw. Some treasures can be found hidden in the precious rocks, like a gold nugget in the Marmolada ring. The texture is the main protagonist of the pieces: these rings are made to be moved between the fingers while we recall unconscious memories and emotions.
