This one isn’t for the timid or the shy. Samantha House’s Lauren Kay Necklace is made of thick slices of gold-plated agate with nude quartz overlay, suspended securely from a snaking gold chain. An obvious, but no less impactful choice, wear this attention-grabber with a simple black v-neck t-shirt and keep the ensemble monochromatic for maximum impact. Dress it down with a pair of inky-black, skinny jeans, or slip into a slimming pencil skirt (leather, please!) for a more sophisticated look. And heels (obviously).
