As if her singing career doesn’t keep her busy enough, Alicia Keys is taking on jewelry design. The 12-time Grammy award-winning R&B singer is teaming up with The Barber’s Daughters designer Gisele Theriault for a collection of necklaces due out in fall 2010. Alicia first met Gisele while she was touring in Toronto through her bandmates, who happened to be buying the jewelry backstage at her show. “I fell in love with the individuality of the pieces, but more than that, the words that were written on them really resonated with the songwriter in me,” Alicia tells WWD about Gisele’s pieces, which are inscribed with poetry and prayers. “I knew at that moment, for the first time, that through a whole other medium I would be able to spread inspiration, and that’s what got me started.” Alicia’s collection of necklaces for The Barbara’s Daughters will range in price from $85 to $2,500 and feature precious metals and gems inscribed with inspirational messages. And while the collection won’t be available until next year, New Yorkers will get a first look and chance to purchase her baubles next week during a two-day preview at a temporary shop at Collette Blanchard Gallery at 26 Clinton Street. Alicia’s jewelry has already gotten some celebrity love from Halle Berry, who purchased a one-of-a-kind piece for $40,000 at a charity auction
