Made from a single piece of rock crystal with natural cleavage. 1 7/8" height of round section bulbous form with cylindrical neck. Bored with a single hole and not under cut as it was used by sticking the finger in to contact the pigment. That construction is typical, though these are far more commonly found of alabaster. Undamaged with expected surface degradation from time and burial and interior stain from its contents, indicating it was buried nearly on its side.
