A spill of colored gems on black velvet. A glossy black spring barrette heaped with marquise-cut crystals — a base of champagne-clear stones scattered with emerald, ruby or sapphire-colored accents, each one prong-set at its own angle so the color flashes up at random as you move. The black base keeps the mix rich instead of riotous: jewelry-box abundance with a composed, vintage soul.
