The optical effect is due to reflections from inclusions of red copper, hematite, or goethite, in the form of minute scales, which are hexagonal, rhombic, or irregular in shape, and are disposed parallel to the principal cleavage-plane.These inclusions give the stone an appearance something like that of aventurine, hence sunstone is known also as "aventurine-feldspar". a metamorphic rock composed, like granite, of quartz, feldspar or orthoclase, and mica but distinguished from it by its foliated or laminated structure gymnosperm a member of the division of seed plants with the ovules and hence seeds, borne on a sporophyll or cone scale, and not borne in an ovary. The black grains can be biotite or hornblende. Ringing rocks Microcline (KAlSi 3 O 8) is an important igneous rock-forming tectosilicate mineral.It is a potassium-rich alkali feldspar.Microcline typically contains minor amounts of sodium.It is common in granite and pegmatites.Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase.
