From the Bobbi Brown Fall 2010 Collection called Black Velvet, this is the gloss created especially to go with the color palette of the entire collection. It is named Black Chocolate.
It looks very dark in the tube, but it applies as a sheer chocolate cherry color, almost a brown berry. It is full of glossy shine and even has soothing botanical extracts in it to keep lips soft as it is worn.
