A sunstone (microcline) is a feldspar with golden spangles, which is caused by regular inclusions of hematite flakes. The scales are at a slight angle to the cleavage of the spar, due to which bright flashes play and shimmer with iridescent colors.
Also, the sunstone has another name - heliolite (a more jewelry position)
Fragments of cleavage are of good quality and perfectly translucent, sometimes translucent with microinclusions of hematite and goethite in the form of small flakes - sequins.
