This Oscar de la Renta masterpiece is made of chalcedony, turquoise, amethyst, quartz, chrysoprase and fresh water pearls... what is a chrysoprase? I actually haven't heard of it. Anyway, the mix of six stones to a 22k gold plated chain really looks nice. I love the whimsical character of it... it actually looks better when worn. You can get this at Saks for $832.99 previously $1,900.
