I didn't pay much attention to the dentritic agates coming from one of several agate sites of Madagascar mainly because they tend to be too big for me to cut. The agates are heavily weathered brown skinned agates showing bandings, "eyes" and other structures and the true colors are well hidden within them that can be revealed only by cutting or breaking them. The agates tend to be colorless to white, sometimes with yellowish tint and varying amount of dentritic inclusions. Some people tumble-polish the rough pieces to bring out the dentrites along the surface of the agates, hence, "Dentritic Agate".
    In some rare cases, we can have the agates from that location with showy brown, orange, black, yellow and white colors, and sagenite structures.
