Colors of the Universe AD1 Earrings, hand made by Rose Carvalho. The shapes and colours of the universe have always been permanent reasons for exploration and contemplation in the work of designer Rose Carvalho and constantly inherent to her creative process. This collection of one-of-a-kind pieces in Art Deco design with special cut gems is inspired by the colours of supernovae and nebulae, in 18kt white gold blended with a uniquely coloured palladium, with Indicolite Tourmalines and Ametrine gemstones illuminated by White Diamonds.
