1. Value and hardness: the hardness of jadeite is lower than that of tourmaline, and tourmaline is second only to that of diamond, so they cannot be worn on the same part to avoid scratches after rubbing. The value of jadeite is generally higher than tourmaline, because the more jadeite is worn, the more shiny it becomes, and tourmaline will fade with time.

2. Different definitions. Jadeite is a kind of fibrous aggregate composed of pyroxene minerals mainly composed of jadeite minerals. Tourmaline, also known as tourmaline and rainbow gem, is a very complicated boroaluminosilicate.

Tourmaline and jadeite are different in composition. Tourmaline is a borosilicate crystal, and the main component of jade is calcium magnesium silicate. With different hardness, tourmaline has higher hardness and jadeite has lower hardness. Different in texture, tourmaline is completely transparent or translucent, and jadeite is translucent or opaque. Tourmaline and jadeite are different in kind, color and texture.

4. Tourmaline is different from jadeite: Tourmaline is a kind of gem-grade tourmaline, which is a borosilicate crystal, containing chemical elements such as aluminum, iron, magnesium, sodium, lithium and potassium, showing various colors. Emerald belongs to fibrous aggregate and consists of pyroxene minerals mainly jadeite.
