Moonstone

What creates the rolling blue sheen in moonstone?

The ethereal glow in moonstone, known as adularescence, is created by light interacting with thin, alternating layers within the stone's structure. As light travels through these microscopically thin layers of feldspar, it scatters and reflects, creating the billowing, moonlight-like effect. This optical phenomenon is similar to the way moonlight reflects off water, which is partly why the stone earned its poetic name. The quality and intensity of this effect can vary between specimens.

Why does my moonstone appear different under various lighting conditions?

Moonstone's appearance changes dramatically depending on the lighting conditions and viewing angle because its characteristic glow is an optical effect rather than a fixed color. In natural daylight, the stone's adularescence is often most visible, while artificial lighting can create different effects. Some moonstones appear more ethereal in soft, diffused light, while others might show their best color play under direct lighting. Try viewing your moonstone under different light sources and angles to discover its full range of effects.

How do I care for my moonstone to maintain its lustrous appearance?

Moonstone is relatively soft (6-6.5 on the Mohs scale) and requires gentle care. Clean your moonstone with a soft, damp cloth and mild soap if needed, avoiding harsh chemicals or ultrasonic cleaners. Store it separately from harder stones to prevent scratches, ideally in a soft pouch or lined box. Avoid sudden temperature changes and prolonged sun exposure, which can affect its appearance. While moonstone can be worn in jewelry, be mindful of protecting it from impacts and scratches during everyday wear.
