Moonstone and Adularescence Explanation: Exploring the Mystical Properties of Moonstones and Their Rare Luminescence
Moonstones, a popular gemstone within the feldspar group, are renowned for their unique optical effect known as adularescence. This captivating shimmer, which can range from soft white to vibrant blue, is primarily caused by the diffraction and scattering of light between extremely fine, alternating layers of orthoclase and albite feldspar within the stone [1][3].
High-quality moonstones, often referred to as "blue flash," are particularly prized for their vivid and electric appearance. The effect is most noticeable in colorless, semi-transparent to transparent specimens [1][4]. In contrast, the whitish or silvery adularescence is more common and appears as a soft, cloudy sheen, caused by variations in the thickness of the feldspar layers and the presence of other minerals [1][4].
The quality and transparency of the moonstone, along with the specific structural properties of its feldspar layers, determine whether the adularescence appears blue, white, or silvery. Moonstones, including the coveted rainbow moonstones, are among the most desirable of the phenomenal gem materials, known for their optical effects in addition to their body colors [2].
Labradorite, another feldspar, is a well-known iridescent gemstone, with blue, green, yellow to orange, and reddish iridescence in some stones. These colours may be separated by straight boundaries. However, unlike moonstone, Labradorite does not contain adularescence [1].
Moonstones are not as famous as rubies, sapphires, and emeralds but are appealing gemstones available in a wide range of qualities and values. They are extensively used in the jewelry trade and have even been designated as the state gemstone for Florida in the USA, due to the manned Moon landings being launched from Cape Canaveral [5].
For moonstones to display adularescence correctly, they need to be cut in the correct orientation, usually at 90° to their base [6]. Coarser structures in exsolution produce whitish to silvery reflections, while smaller ones are needed for the more favoured blue adularescence [6].
Moonstones are valued based on factors such as body color, transparency, freedom from inclusions, iridescence brightness, cutting style, orientation, and size. Stones with a reddish iridescence may attract a premium, as with rainbow moonstones [2].
In addition to their optical effects, moonstones are also generally accepted as a birthstone for the month of June [7]. Some moonstones may exhibit reddish long-wave fluorescence, while Labradorite may fluoresce whitish in long-wave UV [1].
In conclusion, the allure of moonstones lies in their unique adularescence effect, which adds an ethereal quality to these gemstones. Whether you prefer the soft, cloudy sheen of the whitish or silvery adularescence or the vibrant, electric blue of the high-quality moonstones, there is a moonstone to suit every taste.
