6.8 x 4.4 x 5.5 cm
2.7 x 1.7 x 2.2 in
Ex. A. Neely, 1960s
Although, from this location, there were quite a number of specimens of Calcite over Celestine made available in the 1960s and 1970s, the vast majority of specimens were dipped in acid to etch away some of the Calcite to better expose the Celestine and enhance the appearance of the Calcite. This was only done to the point of making the Calcite have a rounded appearance and were often referred to as 'Popcorn' Calcite. This is a completely, undoctored specimen and although not as attractive as one of the acid etched specimens, is considerably more rare.
Flaws: With so many, fine crystals, there are undoubtely a few that are incomplete; but, this is not noticable.
