Also known as Nephrite Jade, this stone is very well known for being a Good Luck and Prosperity stone.  So, when you need to change your luck or increase your value, this is the perfect stone to use. In China, Jade has been the most highly esteemed stone throughout recorded history.  
Jade is also a great stone to use in crystal grids or any other manifestation program, especially if luck is needed.  For example, if you are trying to sell your home or if you are looking for a new job, this would be a good choice!
When working with the Heart Chakra, Jade helps strengthen your connection to other people.  Historically, it has been used to attract love. It also helps to build self-confidence, courage and wisdom into new situations.
Scientifically, Jade is the name shared by two distinctly different minerals - Nephrite, a calcium magnesium silicate, and Jadeite, a sodium aluminum silicate. Though they have different compositions, hardness, densities and crystal structures, both are exceptionally tough stones, similar in appearance, and equally valuable in metaphysical properties. Both occur in the beautiful olive shades we've come to recognize as jade green, but have some distinctions.
Nephrite generally occurs in creamy white, mid- to deep olive green, brown and black. It has a smooth surface polish with a waxy sheen and is more commonly found. Jadeite may be a white-gray green, leafy green, blue or blue-green, emerald green, lavender, pink, red, orange, greenish-black or black. It is hard and lustrous, rarer than Nephrite, and usually more expensive. Translucent, emerald green Jadeite, colored by traces of chromium, is called Imperial Jade and is the rarest and most valuable.
