The double refractive feldspar has a special status among stones. Light is refracted into the spectral colours by means of polarisation at the inner layers and not like in a prism by reflection at the edges. This apparition of colours is caused when light falls on to the transparent stone and, upon closer observation, is refracted into the magnificent colours of the rainbow in the inner layers of the stone. Transparent stones have always been particularly treasured. They combine the element stone, which has a high density, with the fluid light. The chosen double refractive feldspar is set within a moveable, protected mounting which is embedded in a black granite stone.
