WHAT IS MOONSTONE?

 

  • Moonstone is a feldspar gemstone famous for its adularescence—a soft, glowing light that appears to float across the surface of the stone, giving it a mystical and ethereal appearance.

WHAT CAUSES MOONSTONE'S GLOW?

 

  • The glowing effect, or adularescence, occurs due to light scattering between microscopic layers of feldspar within the stone. This optical phenomenon creates the characteristic floating light seen in moonstones.

IS MOONSTONE FRAGILE?

 

  • Moonstone has a hardness of 6–6.5, making it more delicate than sapphires or spinels. It requires careful handling and is best suited for earrings, pendants, and occasional-wear rings rather than everyday jewelry.

WHAT COLORS DOES MOONSTONE COME IN?

 

  • Moonstone ranges in color from colorless to white, peach, gray, and even rainbow varieties with blue or multicolor flashes. Each stone is unique, and its color and glow can vary depending on the angle of light.

HOW SHOULD I CARE FOR MOONSTONE?

 

  • Clean moonstone gently with a soft cloth and mild soap. Avoid ultrasonic cleaners, harsh chemicals, and sudden temperature changes. Store moonstone jewelry separately to prevent scratching from harder gemstones.
