* Jadeite is a sodium aluminum silicate with the chemical formula NaAlSi2O6. It is a pyroxene mineral that is formed by the metamorphism of aluminum-rich rocks. Jadeite is typically translucent or opaque with a hardness of 6.5 to 7 on the Mohs scale. It can come in various shades of green but also can be lavender, red, yellow, orange, or brown.
* Nephrite is a calcium magnesium iron silicate with the chemical formula (Ca,Mg)5(Si,O,OH)4. It is an amphibole mineral that is formed by the metamorphism of magnesium-rich rocks. Nephrite is typically translucent or opaque with a hardness of 6 to 6.5 on the Mohs scale. It is most often green, but it can also be yellow, white, or brown.
Jadeite is typically more valuable than nephrite. Both types of jade are prized for their beauty, durability, and symbolic significance. They have been used for thousands of years in jewelry, carvings, and other decorative objects.
