15x10mm Rainbow Moonstone
This piece was designed using Matrix 3D, a Jewelry Design Software. And cast using the lost wax method of casting.
Moonstone or "Adularia", an orthoclase feldspar, was originally named for an early mining site at Mt. Adular in Switzerland. From this tradition we derive the term "adularescence" which is the optical phenomenon of iridescence which creates a billowy, floating blue to white light in this gem. Adularescence is due to diffraction of light as it hits thin, alternating layers of orthoclase and albite within the gem. Very thin layers produce blue "schiller" and thicker layers produce white. Body color is generally due to iron content.
