[Sale on 8/6 at 10 PM JST] Colombian Pyrite and Mica in Emerald, 4.8mm/0.360ct, Loose Stone with Certificate
The beautiful green of an emerald is said to vary in color depending on its origin. This particular emerald is from Colombia, known for its particularly deep green hue. Emeralds are generally stones with many inclusions, so oil treatment is commonly used to make them less noticeable. Please enjoy this elegant green. This is an emerald with pyrite inclusions.
This is a round-cut 4.8mm pyrite-included emerald from the Chivor mine in Colombia. An identification certificate is included.
