Uses & applications
Widely used in high-end jewelry, carvings, ornaments, and amulets due to its cultural significance and toughness.
Geological facts
Jadeite is one of the two minerals recognized as jade, the other being nephrite. It is extremely tough due to its microcrystalline interlocking fibrous structure.
