Beyonce has been promoting her multiple-personality album I Am…Sasha Fierce, which will be released tomorrow, and in at least three recent performances — the World Music Awards, the MTV Europe Music Awards, and “Saturday Night Live” — she has worn a piece of jewelry that resembles the hand of a robot. Upon closer inspection, you’ll notice that the glove is basically a full-hand ring. At first, we thought Beyonce was wearing her special glove whenever she performed as Sasha Fierce, her sassier alter-ego, but this theory doesn’t pan out because she wore the hand when she performed “If I Were A Boy,” which is on the Beyonce part of the album. The accessory, which we’re calling a “gling” (glove ring), was designed by Lorraine Schwartz, who also created Beyonce’s $5-million, 18-carat diamond wedding ring. Seeing as Schwartz’s designs cost a pretty penny, maybe Beyonce is wearing the gling non-stop because she wants to get her money’s worth. Either that or she’s just one of the first to sport finger-surrounding rings — Vogue Italia featured several in a recent story, and Selma Blair wore one shaped like a snake this weekend.
