Any worker unit can mine Jade, although Dwarves are the game's most efficient miners. As with Gold Mines, there are small, medium and large Jade Mines, each providing a different amount of gold; small ones provide 1,500 gold, medium ones provide 3,000 gold, and large Jade Mines provide 6,000 gold.
"Considered the "imperial gem", jade could be found in natural deposits underground or in rivers in the form of pebbles and small boulders. Used for hardstone carving, jade was acquired by ancient civilizations to create both delicately-shaped weapons and decorative objects, among others the mouthpieces of some pipes as it was believed that breathing through jade would bestow longevity upon smokers. Precious white jade attained a higher status-value than silver or gold and served for both utilitarian and ceremonial purposes."—In-game help section
