Jadeite is green, yellow, purple and white in color. Jadeite has uneven distribution on color across the stone thus has different texture. Pure Jadeite comes from Burma. Because Jadeite comes in different colors so it is used in jewelry more than nephrite and so more expensive.

Nephrite

Nephrite is usually only green and creamy white, while jadeite can have the full range of jade's colors.
