we're Obsessed!

I always like a mashup of unusual materials in fine jewelry—an offbeat mix adds an element of surprise. The Italian master jewelers at Bulgari completely caught me off guard with the latest rendition of the B.zero1 ring by mixing marble into the design. The pink gold and mottled green stone create a look that is perfectly in line with fashion's new minimalism. The age-old rock also reminds me of my last trip to Rome: the cracked steps of the Colosseum, the white floors of the Parthenon. The material is as eternal as the ancient city.
