A rare Arkansas Japan law twin, and of considerable size, too! I am told that this piece was a famous blunder Dick was proud of, acquired in the 1960s from somebody who did not know the rarity of such things and used to illustrate how an awareness of unusual crystallography could help buy value in minerals. This is VERY significant for the locality, for a US quartz twin of this habit. It is unusually big and fat, for Arkansas twins, as well. The piece is complete both sides and has no damage of note save a small conchoidal bruise on the back of the leftmost temrination - a sad fact to be sure, but not visually distracting or significant in context.
