jade pen gift

Jade pen gift Jade is the gem name for mineral aggregates composed of either or both of two different minerals, Jadeite and Nephrite. Jadeite is a sodium-rich aluminous pyroxene; nephrite is a fine-grained, calcium-rich, magnesium, iron, aluminous amphibole. All jade is composed of fine-grained, highly intergrown, interlocking ("matted" or "felted" texture, like asbestos or felt) crystals of one or both of these minerals. Though neither mineral is very hard (6-7), jade is one of the toughest gem minerals known because of the intergrown nature of the individual crystals. Most jade on the market is composed of nephrite; jadeite jade is quite rare and in its emerald-green, translucent form is referred to as Imperial Jade or "gem jade". A small amount of Cr in jadeite accounts for the color of imperial jade. Other color-based names for jadeite jade are Yunan Jade, for a uniquely appearing dark green, semitranslucent jade, Apple Jade for apple (yellowish green) green jade, and Moss-in-Snow for white jade with vivid green spots and streaks.
