Courteney Cox and David Arquette have headed back to the design studio just in time for the holidays. The husband-and-wife design team have been working with Satya Jewelry since 2007 on a collection of butterfly-inspired jewels to benefit the EB Medical Research Foundation, a cause close to the Arquettes’ hearts. “There is a beautiful child named Brendon, the son of one of our dear friends, Andrea Pett Joseph, who was born with Epidermolysis Bullosa or EB [a rare skin disease],” David tells Vogue.com. “We were not aware of the condition until it affected us personally but, of course, once we got to know this incredible child we wanted to do whatever we could to help.” Since the launch of their EB jewelry collection, the Arquettes and Satya Jewelry have raised over $200,000 to benefit EBMRF. For this upcoming holiday season, David and Courteney have added three new pieces to their collection, including a new butterfly pendant, a new “hope” pendant and an onyx, blue topaz and turquoise bracelet with a sterling silver charm. The collection ranges from $38-$68, with 100% of the proceeds benefiting the EBMRF. Click here to shop Courteney and David’s EB collection for Satya Jewelry.
