Cobaltocalcite - 11.45 carats

Cobaltocalcite is a rare variety of calcite colored by traces of cobalt. This gem is notable for its highly saturated color and superb translucency, with an amazing glow when backlit. Gem-quality cobaltocalcites over 10 carats are very rare, especially in this vivid color. This fine specimen will delight the most discerning collector. Guaranteed natural and untreated by GIA, including a Notable Letter which states that "The large size, highly saturated reddish purple color and high degree of transparency makes this a notable cobaltocalcite."
