Clearly seen with the naked eye, this unusual Herkimer Diamond holds a fluid filled inclusion with a crystal sphere floating in it!
Some refer to these Herkimer Diamonds as enhydro's, but this is actually incorrect. What's the difference? A scientist will tell you a fluid filled inclusion is fluid, generally water based, sealed within a crystal during its growth. While enhydro does mean fluid filled, this fluid is not necessarily sealed inside. A fracture could have allowed it to enter, and thus escape. In a nutshell, fluid in an enhydro is able to move in and out of the crystal, where as a fluid filled inclusion contains fluid that was trapped inside when the crystal formed. In the case of a Herkimer Diamond, that is over 300 millions years old!
Floating inside the inclusion is a crystal sphere. These spheres are a relatively new finding at the Herkimer crystal mines. They have been found in Herkimer and Fulton counties and are always less than 10 mm. Most have a frosted surface.

Clarity of this double terminated quartz crystal is excellent. Except for the "enhydro" and a couple of gaseous inclusions near it, inside it is clean.
Externally flawless, but for tiny clear matrix mark and a fairly large key mark.
is present near one tip. It looks more pronounced in the pictures than in person. It does have some geometric design to it, but might actually be a hopper marking rather than a key.
While the fluid filled inclusion and crystal sphere can be seen with the naked eye (it's about 3/8"), when viewed with a loupe this crystal is awesome! It's a high quality B grade Herkimer Diamond.
