Its name comes from a visual effect, or sheen, due to the light diffraction within a micro-structure consisting of a regular of feldspar layers (lamellae).
We used moonstone in jewelry for millennia, including ancient civilizations. The Romans admired this gemstone, as they believed it was born from solidified rays of the Moon.

The plagioclase feldspar oligoclase also produces stone specimens. It is feldspar with a pearly and opalescent schiller. An alternative name is hecatolite.
Orthoclase and albite
Black star moonstone is composed of two feldspar species, orthoclase and albite. The two species are intermingled. Then, as the newly formed mineral cools, the intergrowth of orthoclase and albite separates into stacked, alternating layers.
Adularescence is a blue sheen phenomena reflecting on the domed cabochon surface of black star moonstone. The phenomena of shimmer comes from the interaction of light with layer of little “albite” crystals in moonstones. While the thickness of layer of these tiny crystals determine the quality of blue shimmer. Therefore, thinner the layer, better the blue flash. This usually appears as a billowy light effect.

It crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.
