DANIA BEACH, Fla. – Many believe that buying what one likes, as opposed to speculating on an object’s potential to increase in value, is the only sensible way to collect, whether it’s comic books or French cameo glass. The globetrotting Florida couple who acquired this elegant Rene Lalique perfume bottle during their travels across Europe probably never gave a thought to its value beyond its obvious beauty, but both their taste and innate buying sense proved to be impeccable. The 4.75-inch rose-hued vessel, in flawless condition and etched with an “R Lalique” signature, was auctioned on April 26 for $57,950.
