A beautiful example of a quartz crystals twinned on the "Japan Law" after the first major place the twinning was noted from. This example shows the, close to, 87 degree 33 minute angle that such crystals must be conjoined at and has a nice "suture" line at the interface of the two twin members. From a, I believe, worked out locality.
