The night was a celebration of the launch of Simon G. Jewelry’s new line of sustainable jewelry, which will benefit Global Green U.S.A. The evening was hosted by Melissa Rycroft and included musical performances from Robin Thicke, CJ Goldner, Dr. Hollywood, and a debut performance from Jessica Lowndes of “90210.”

Also in attendance was “Twilight” star Nikki Reed, who donned an array of Simon G. Jewelry for the event. “I love how deep the Simon G. jewelry collection is,” Reed said. “Simon G. is so versatile from amazing delicate pieces to hard core edgy pieces.”

You can see Nikki Reed in action later this month, when the latest Twilight film, “The Twilight Saga: Eclipse,” launches nationwide.
