    Gemstone: Calcite - 39.16 Cts.
    Santa Rosalía, Mun. de Mulegé
    Baja California Sur (BC Sur)

    Calcite is not a common mineral to find cut and faceted, despite it being one of the most ubiquitous minerals on Earth. This large stone weighs in at nearly 40 carats and displays a beautiful, highly saturated, golden honey hue. The stone has a nice cut with good proportions. The fancy shape and facets add to the stone's overall appeal. Not only does the stone display birefringence; it also exhibits phosphorescence when viewed under long-wave ultraviolet light. This stone is eye-clean with only very minor nicks to the culet. This is very impressive considering the stone ranks only a "3" on the Mohs hardness scale. Overall, this remarkable gemstone from the collection of Bernadine Johnson is in excellent condition.
    Measurements: 21.86 x 20.48 x 14.3 mm, 39.16 cts.
