Jadeite bead necklace - Christie's Hong Kongthe rarest precious stone is jadeite valued at $3 million plus per carat?

While not to be confused with jade, a term used to refer to both jadeite and nephrite, only jadeite retains value as a rare gem.  With the best gem quality jadeite found in Myanmar (Upper Burma), other lesser quality sources include Guatemala, Russia, Kazakhstan, Japan and California.  Jadeite’s value is judged by the combination of the intensity of green color and high degree of transparency.  At Christie’s in 1997, a jadeite necklace called the “Doubly Fortunate” set the highest price for a piece of jadeite jewelry sold at auction, selling for $9.3 million.
