It should be a crime to glimmer and shine this bright with such dark hues! Mysterious and sleek, this deep blue diamond with perfectly placed chiseled cobalt swarovski crystals is an amazing gem for that late night dreamy/dreary 1920's vibe. Trouble maker? Likely. Troubler maker with couture style? Proven with this multidimensional midnight diamond necklace. Heck yes, UNISEX! Sterling silver 18" chain.
