Mineral Specimen #6463 Calcite with Micro Sulfide Crystals
Highland Co., Ohio
8.1 x 6.3 x 4.3 cm
3.2 x 2.5 x 1.7 in
Ex. A. Neely, 1960s
There are a number of quarries located in Highland County, several of which are abandoned and flooded with at least one still in operation. It is unclear from which quarry this specimen came. That being said, specimens from the county are quite rare with only one having been posted on mindat. Aaron Neely owned a rock shop, Neely's Rock Shop, in South Salem which is in Ross County but very close to the Northeast corner of Highland County and he presumably had a local source (the name of the quarry may have been omitted to protect the source). There were several specimens of Sphalerite in the stock from his shop from Highland County, but this was the only Calcite specimen. The crystals are flattened twins, have a dull luster and a muddy, beige color. The edges of the crystals are sprinkled with micro crystals of some type of sulfide which are too small to distinguish even under 10x (best guess is Pyrite based on the color).
Condition: Fairly Good
Flaws: Some of the edges of the crystals are worn/bruised.
