Idriss Guelai Atelier

FLORENCE, ITALY - JULY 16: (ITALY OUT) Florentine craftsman artist of French-Algerian origin Idriss Guelai poses in his atelier with one of his jewel sculpture on July 16, 2013 in Florence, Italy. The 45 year old artist artist-craftsman started as a decorator and costume designer for discos and today creates precious sculptures using a variety of materials. A photograph of Madonna wearing a mask jewel created by Idriss Guelai appeared in many newspapers around the world and across social networks. The singer pre-empted a fashion shoot undertaken for Harper's Bazaar and due out in November, by instagramming a photograph of herself while wearing the Idriss Guelai's jewel mask with the phrase: "The Revolution of Love is on".
