Moonstone has an appearance similar to that of other Moonstones, as she has a mostly thin build with blue skin, four eyes, and two arms, however she does have a thicker and slightly stouter build. Her skin is pastel blue and her four eyes are yellow and blue with black pupils and some black eyebrows on her top pair. Her nose is sloped and pointy and her mouth is small with defined lip. Her hair is short and light blue and is messy and sloped to the left. Her gemstones are on her right forearm and left side of her thigh and are white, blue, and yellow.
She wears a white and yellow shirt with a string v-shaped neckline with a navy blue accent at her collar and sleeves. Her bodysuit is teal and starts at her waist and covers all of her right leg and a small part of her left leg. She also wears navy blue boots that have an unknown appearance based off of her picture.
Moonstone is a sodium potassium aluminium silicate, with the chemical formula (Na,K)AlSi3O8.
Its name is derived from a visual effect, or sheen, caused by light diffraction within a micro-structure consisting of a regular succession of feldspar layers.
Moonstone has been used in jewelry for centuries, including ancient civilizations. The Romans admired moonstone, as they believed it was born from solidified rays of the moon.
Both the Romans and Greeks associated Moonstone with their lunar deities. In more recent history, the moonstone became popular during the Art Nouveau period; French goldsmith René Lalique and many others created a large quantity of jewelry using this stone.
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. When light falls between these thin, flat layers, it scatters in many directions producing the phenomenon called adularescence.
