A ring - jade, jadeite, peridot

Jade is actually two separate gems: nephrite and jadeite. In China, a pierced jade disk is a symbol of heaven. Nephrite jade in New Zealand is known as pounamu in the Māori language, called "greenstone" , it plays an important role in Māori culture. Jadeite is the rarer of the two varieties of jade, and as a result it is more precious. The most valuable variety of jade is a striking and even emerald green jadeite, known as "imperial jade" Jade ranges in colour. It occurs in green, white, orange, yellow, lavender, grey and black. The most highly valued jade is a vivid emerald green and is semi-transparent. It is known as imperial jade and only occurs in Burma (Myanmar).
