[Item No. 12562799] Colombian Pyrite-in-Emerald Loose Stone, 2.780 ct

The beautiful green of emeralds is said to vary in color depending on their origin. This particular emerald is from Colombia, known for its especially deep green hue. Emeralds typically have many inclusions, so oil treatment is commonly used to minimize their visibility. Enjoy the elegant green color. This is a pyrite-in-emerald.
This is a pyrite-in-emerald from the Chivor Mine in Colombia. The Chivor Mine is known for producing beautiful bluish emeralds. This particular loose stone features pyrite inclusions within the emerald. The addition of metallic luster from the pyrite gives it a unique appearance compared to a simple emerald, showcasing its individual character as a mineral.
Such pyrite-in-emerald stones are known not only for their interesting appearance but also for the difficulty in polishing them. This is because emerald and pyrite have different hardnesses, with emerald being harder. During standard polishing, the pyrite areas tend to indent. Therefore, these stones are carefully and painstakingly cut locally in Colombia. Because different minerals coexist within a single stone, a high level of skill and care is required in the finishing process.
