MINERALOGY: The feldspar is an inorganic substance that forms the main part of many igneous, sedimentary, and metamorphic rocks, chemically is a composite aluminum silicate, potassium or calcium, and small amounts of oxides of magnesium and iron, feldspars are generally High temperature rise with more disordered structures passing by cooling, to a temperature less orderly state. Such is the case of sanidine polymorphs (high temperature), orthoclase (intermediate) and microcline (low temperature). The inclusions are common in rubí. El corundum source is magmatic andesite, basalt and pegmatite, metamorphic.

MYTHOLOGY: The feldspars are the most abundant primary mineral in earth's crust, also is a major source of potassium and calcium, los feldspars are divided into two groups: group orthoclase or potassium feldspars, and the group of plagioclase feldspar and sodium-cálcicos.En ancient cultures of India ruby ​​was known as the "Sun Stone" by depicting the inner fire, love and passion.
