POLISHED JADE SPHERES

Jade is a semi-precious stone best known for its dark green varieties, though it can be found in a variety of colors. The most common types of jade are jadeite and nephrite. Jadeite is a variety of jade primarily composed of silicon, calcium, and magnesium, while nephrite contains silicon, sodium, and aluminum. For thousands of years, jade has been used for ornamental purposes such as jewelry and as tools due to its relative strength and durability.
