A strange duo where the quartz crystal continued interrupted growth, but that interruption let a permanent barrier set up between the two portions of the crystal and so instead of a phantom, we have a detached "cap" that sits upon the original matrix and earlier crystal growth. REALLY WEIRD things, these! I have seen these bizarre "russian doll" quartzes before only from a few historic samples out of Cornwall, but this seems a valid example from somewhere else, the first I have seen. The old Lazard Cahn label dates this to 1927-1940, though it probably came to him already in an old collection, one would think.
