Amazonite:
Tectosilicates
(Potassium aluminum silicate) KAlSi3O8 AKA: Amazonstone, Orthoclase, Potash feldspar |
|
System: Triclinic (microcline); predominantly as single crystals of rectangular or square cross section and as tabular crystals; twin crystals very common; also cleavage masses, granular, disseminated grains. Appearance: Light bluish-green; vitreous; streak white. Physical properties: Hardness: (6.0 - 6.5), Specific gravity: (2.5 - 2.6), Cleavage: Good in two directions at 90 degrees; fracture, uneven; transparent to translucent. Similar species: Similar silicate minerals lack the right-angle cleavage. Occurrence: These minerals are very widespread in their distribution in North America. The finest crystals of microcline- amazonite- occur in pegmatites in the Pikes Peak area of Colorado. Gem amazonite has been obtained from Virginia. The finest amazonite comes from Brazil. Miscellaneous: Laminations (striae), which are common, and white streaks are not desirable in amazonite. Conventional Wisdom: It was named for a mistaken belief that its primary, and perhaps only, source was the Amazon River. Crystal mystics have paid little attention to it because it is not well known, not expensive, is not usually considered a gem, and is not mentioned in either ancient or modern myths.
