Gemma Redux Ami Necklace with PeridotAmi necklace from Gemma Redux by Rachel Dully really stands out with the large peridot quartz as the focal point. The stone is well balanced by the cascade of steel chains. It would look great with a low cut dress, but one has to make sure to not overdo the rest of the outfit since this necklace and the low cut are dramatic enough. $270 at CoutureCandy.
