Large Prismatic Green Willemite Crystals in Fine Calcite Franklin New Jersey

Description

Here is a super neat specimen the likes of which I haven't seen before.  The whole specimen is covered in an almost aquamarine-green willemite much of it has prismatic crystals that are partially poking above the fine-grained calcite in which they formed.  They are also quite gemmy and semi-transparent.  It doesn't look like someone etched it with acid, it looks like it formed in or around a dissolution pocket of some sorts.  The willemite crystals on the inside are extremely long and elongated, very neat specimen!
