I had a customer ask me this question ... so a quick answer is this. "Jade" refers to a green carvable stone, and depending on where it is coming from it will be either Jadeite or Nephrite.
What are the main differences between Jadeite and Nephrite?
First of all Jadeite and Nephrite are very different minerals.
They have different properties:
- crystal structure
- chemical composition
