GEO, what an incredible design! I love the rough element in a high end jewellery setting! Edgy and bold but still elegant and chic. I normally prefer white or rose gold, but I think a yellow gold in this design, allowing the scratches to form and the patina of the yellow to roughen into a brassy tone, it will actually be more appropriate because a lot of nails are in brass too. White gold should work too, but I believe brass is the new gold!!! Non?
