Anna Tomich from Lotocoho. I'm a sucker for faceted jewelry and Anna Tomich sure knows how to make those. The pieces are inspired by mountain structures. You can even let her know what your favorite mountain is and she'll design a piece for you.
I also love french jewelry designer Violaine Ulmer. She makes beautiful strong and huge rings out of porcelain and paints them in gold silver and metallic. One ring was screaming my name, but I resisted.
