The presence of feldspar lamellae in another feldspar gives rise to the Schiller effect, an iridescence due to light refraction. Schiller is best developed in labradorites, creating a lovely color play in shades of green, blue, gold and yellow. The color may be uniform or vary within a single feldspar crystal.

Feldspar - Wikipedia

Feldspars are a group of rock-forming aluminium tectosilicate minerals, containing sodium, calcium, potassium or barium. The most common members of the feldspar group are the plagioclase (sodium-calcium) feldspars and the alkali (potassium-sodium) feldspars. Feldspars make up about 60% of the Earth's crust, and 41% of the Earth's continental crust by weight.
