The well formed Witherite crystals that make up this specimen are extremely large for the species. The crystals are a yellow/tan ivory color with the faces being almost white. The crystals are actually stacks of thin, pseudohexagonal, trilling twinned crystals. From the sides, the stacks of crystals exhibit alternating layers of color. When backlit, as in one of the pictures, the Witherite can seen to be translucent. Some of the Witherite crystals have a thin coating of dark colored Bitumen. The matrix contains Fluorite which is bicolored, light purple, and light yellow/beige. There are also a few, small, dark colored Sphalerite crystals. The underlying matrix has a number of casts including some which are curved. There is also a white crust of Alstonite on the matrix on these cast structures.
Condition: Excellent
Flaws: Nothing Appreciable
