These feldspar minerals form a solid solution series between NaAlSi 3 O 8 and KAlSi 3 O 8. The minerals in that series crystallize from melts that usually contain both sodium and potassium ions. At the time of crystallization, these ions can substitute freely for one another in the mineral's crystal structure.
This mineral is often called potassium feldspar or Kfeldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.
Sunstone is an interesting feldspar gemstone with a glittery appearance and usually an orange or reddish color, hence its name.

Identification of specific feldspars.
