Magical Moonstones

Most varieties of moonstone are a pale bluish-white in appearance, with an opalescent beauty that shows different hues the way an opal does.

Adularescence

Moonstone is formed from two types of feldspar – orthoclase and albite. The minerals intermingle at first, then form alternate layers as the stone builds up. These layers create a quality called adularescence, which makes light appear to flow across the stone as you watch it!

Art nouveau

The shimmer of a moonstone’s surface made it a prized gemstone in the art nouveau movement (1890–1920). René Lalique, a French jeweller, used it with other gems to make pieces of exotic jewellery, such as this dragonfly brooch (above).
