Jadeite or Nephrite?
As a gemstone, jade can be one of two minerals: jadeite or nephrite. While both are jade, there are significant differences between these minerals. First, jadeite, a pyroxene mineral, has somewhat greater hardness than nephrite, an amphibole mineral. Still, both are susceptible to scratching. On the Mohs scale, jadeite is 6.5-7, while nephrite is 6-6.5. Nephrite can occur in extremely large sizes. Large jade sculptures are commonly made from this material. Both materials are extremely tough and resistant to wear, though nephrite is somewhat tougher. However, the top color for jade, imperial green, only occurs in jadeite. Additionally, jadeite is more likely to be translucent. These factors, in combination with greater rarity, make jadeite more expensive than nephrite.
