穆佐
Boyacá, Colombia
哥伦比亚博亚卡的穆佐是地球上最著名的祖母绿产地,经典的深邃『穆佐绿』即源于此。
What it is known for
The Muzo mines, worked since pre-Columbian times, produce emerald in calcite–pyrite veins cutting black shale, traditionally noted for a pure, slightly warm green.
What collectors look for
Sharp emerald crystals — on white calcite or in matrix, with strong colour and clarity — are the prize and command very high premiums.
