Here is one of two extremely rare abundance clusters featured in our book, "The Buyer's Guide". The 8h faced host is extremely rare in and of itself, and one of the two faces is a true diamond window: through which you could draw a Christian cross. Overall the cluster is 7/16x 9/16x 3/4" tall, 2 mini-fleabites. Near the termination, is a foil/rainbow, veils at the base. Self-displays. There is a gap: a growth crater where a crystal ripened and came away.
