I'm generally not enamoured of blue topaz. Often set minimalistically in white metal, it can look far to cold and clinical for my tastes - and can feel a little dated.
Diego Percossi Papi's Moon Earrings, however, are topaz on a whole different level. The contrast between the cool blue and warm yellow gold makes them interesting and modern.
Moon/pear drop/star components may not be hugely original in themselves, but the overall composition and finish of these earrings makes something really, really lovely.
