Weight: 3.87 ct.

This particular Herkimer crystal has a fluid filled inclusion in the center. Fluid filled inclusions (enhydro's) are always rare. It is tiny, even with a loupe, and tough to see movement. The bubble can be seen in the first image below.
What really makes this Herkimer crystal so unusual is a phantom key type growth occurrence just beneath the surface of several facets. It's clear, and at first just seems to be a shallow key. Upon closer inspection, you realize it's inside the crystal. I've never seen this before.
External key marks, present on 2-3 other facets, are all well defined and seen in the images.
Please note, while there is a touch of iron oxide, it in no way is as dark as the images show. There is more of a lemony hue on the tips. The thin coating could be removed with Iron Out if desired. Many clients like it, so we leave it up to you.
This unusual A grade Herkimer crystal is water clear with good definition and sharp double termination tips.
