About Transvaal Jade

Transvaal Jade is a massive green to mottled green-and-white grossular garnet, also known as South African Jade, that is mined in the Transvaal region of South Africa and marketed as an inexpensive jade substitute. Its uniform to mottled green appearance, waxy luster, and workability make it a popular material for carvings, beads, and decorative objects, though gemologically it is grossular garnet rather than true jade. Its affordable price and attractive appearance have made it a widely used craft material.
