The perfect lifetime item for your jewelry wardrobe is still a classic pair of diamond studs. They work with jeans and transition to the dressiest outfit as the signature jewelry look for a lifetime . Period. We love this setting-the accent of beautiful round studs with micro set diamonds in 18KT white gold from Martin Katz. They come in all sizes and colors and clarities starting at $8,000. www.martinkatz.com or his Beverly Hills or the Martiz Katz boutique at Bergdorf Goodman in New York.
