Gem Stone is a "member" of The Nega-Fergo Bunch. She's one of Sabrina's rivals (as shown in "I Got Blue, Babe", she's shown to be very dominant over "mates"). She's mean, because she's spoiled from her parents. She loves to be rich and hates being poor. She also wants to have everything she wants. Plus, her heart's darker than her hair. This is speculated, since she supports the anti-g*y Chick-Fil A and the Nega-Barney Bunch. Even The M-san Bunch sometimes cringes at her name!
