Triclinic.
plagioclase, microcline, rhodonite, turquoise, wollastonite, amblygonite, and many more.
Amazonite is a green variety of microcline feldspar that forms in the presence of lead, aluminum, and water. Its color comes from trace amounts of lead within the mineral structure. The unique color and striated appearance of amazonite are due to its crystal lattice structure and composition.
An amazonstone is a blue-green variety of microcline feldspar used as a gemstone, found at Crystal Peak and Pike's Peak in Colorado.
microcline can be used for many different things such as glass and ceramics and u can find it in the mountains of Maine and Michigan.

No, it is not a rock, it is a mineral/crystal.Amazonite is a green variety of microcline feldspar, which does occur in some intrusive, granitic Igneous rocks.
There really isnt a crystal form. Therefore it is a mineraloid.
1.The green variety of microcline amazonite is used as an ornamental lapidary material.2.Microcline is used mainly in the manufacture of porcelain. It is ground very fine and mixed with kaolin and quartz. Upon heating, the feldspar fuses and acts as a cement binding the materials together. Fused feldspar also is the main constituent in the glaze on porcelain.3.Sometimes microcline is also used to supply alumina in the manufacture of glass.by Maham kainat :P
microcline is the answer
Microcline, a feldspar mineral, is generally not magnetic. It typically exhibits very weak magnetic properties, but these are not strong enough to be considered significant or to attract a magnet. Its composition primarily consists of potassium, aluminum, and silicate, which do not contribute to magnetic behavior. Thus, microcline is classified as non-magnetic in most contexts.
All minerals have a crystal form, but not all have cleavage.
Alkali feldspar has the general formula (K,Na)AlSi3O8, but varies in crystal structure depending on the temperature it formed at. The formula actually is a blend ranging from all sodium (albite) to all potassium (microcline), but albite is also one endpoint in the plagioclase series so we classify albite there. This mineral is often called potassium feldspar or K-feldspar, because by definition potassium always exceeds sodium in its formula. It comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400° C. Orthoclase is stable above 500° C and sanidine is stable above 900° C. In a plutonic rock that cooled very slowly to yield large mineral grains, it's safe to assume that this is microcline. In the field, workers generally just write down "K-spar" and leave it at that until they can get to the laboratory. Alkali feldspar is generally white, buff or reddish and is not transparent, nor does it show the striations of plagioclase. A green feldspar is always microcline, the variety called amazonite.
