Tony RewardsBonhams & Butterfields will auction the artistic expressions Holly­wood designer Tony Duquette created during a personal “healing process.” The Talismans of Power auction will follow the 20th Century Decorative Arts Auction in Los Angeles on April 18. Stamped with Duquette’s signature imagery, more than 135 pieces of the elaborate necklace collection with accompanying brooches, pendants, and bracelets will be up for sale. Gold-plated silver, geodes, and exotic and semiprecious stones bring the mystical pieces to life. —Lindsey WojcikClassic Color–Happy Buyers The industry’s appetite for fine color has returned, or so the brisk business at February’s Tucson gem shows would suggest.
