Emerald, Pyrite - Muzo, Vasquez - Yacopi Mining Area, Boyaca, Colombia
 
 The intense dark green of the emerald, embedded on pyrite, stands out particularly rich in contrast from the black matrix and thus forms a classic aesthetic specimen.
 The surface of the crystal is recrystallized.
 Muzo in the Vasquez-Yacopi mining area in Colombia is famous for these intensely coloured emeralds and this piece highlights this particularly well. With a crystal size of 4 cm x 1 cm, it is a large emerald, which is excellently presented on the 9.3 cm x 5.9 cm specimen.
