IMHO, itβs either Alley or Ravenswood. Many are a toss up between the two. Ravenswood is known for having a βracing stripeβ in clear swirls , frequently 9/16β, having folds and twists and dives to the ribbons like worm holes. Swirls tend to cover more surface of the marble and a βwadded upβ appearance to the swirl.
