Calcite twins (classic locale) Robertson Coll.

Item Description

A classic and very aesthetic two-sided butterfly-twinned calcite from Santa Eulalia. The striking, sharp, colorless terminations are dramatically accented with coatings and inclusions of charcoal-gray and rust-brown hematite. The dark sheath around the large rhombs with the surreal "sunspot" spherules on both sides and the fantastic small two-colored twin in the middle add real pizzazz to this very fine calcite. Complete all-around and nearly pristine, with only a small bruise to one of the terminations. Ex Kay Robertson Collection # 1823 and acquired from prominent fellow California collector, Marion Godshaw, in the early 1960s. Kay is a prominent California collector, who specialized in European classics (see the article in the March-April, 2007 Mineralogical Record and the 50+ page article in the German Magazine "Mineralien Welt" November-December 2017).
