JADE CARVINGS

Jade is an ornamental rock - most commonly Green although it appears in many colors. The term jade is applied to two different metamorphic rocks including Nephrite and Jadeite. Nephrite and jadeite were used from prehistoric periods for hard-stone carving. Jadeite has about the same hardness as quartz. Nephrite is slightly softer but tougher (more resistant to breakage) than jadeite. Nephrite can be found in a creamy white form (known in China as "mutton fat" jade) as well as in a variety of light green colors, whereas jadeite shows more color variations, including blue, lavender-mauve, pink, and emerald-green colors. Of the two, jadeite is rarer, documented in fewer than 12 places worldwide.
