Lottery Sale 11 [For Winners Only] [Listing 12562752] Colombian Pyrite in Emerald Loose Stone 2.107ct

This page is exclusively for winners of the lottery sale.

The beautiful green color of emeralds is said to vary depending on their origin. This particular emerald is from Colombia, known for its especially deep green hue. Emeralds are generally stones with many inclusions, so oil treatment is commonly used to reduce their visibility. Enjoy the elegant green color. This is an emerald with pyrite inclusions.
This is a pyrite-included emerald from the Chivor mine in Colombia. The Chivor mine is known for producing beautiful emeralds with a bluish tint. This particular loose stone features pyrite within the emerald. The addition of metallic-lustered pyrite to the emerald creates a different look than a simple emerald. It's a stone with a distinct mineral character.
Such pyrite-included emeralds are known not only for their interesting appearance but also for the difficulty in polishing them. This is because emeralds and pyrite have different hardnesses, with emeralds being harder. Therefore, during standard polishing, the pyrite areas tend to become recessed. For this reason, such stones are carefully cut over a long period of time in Colombia. Because different minerals coexist within a single stone, a high level of skill and caution is required for the finishing.
