Mineralogical Identity & Optical Properties: Moonstone is a celebrated gem variety of the Feldspar (potassium aluminum silicate, KAlSi₃O₈) mineral group, specifically intergrown orthoclase and albite. Its defining optical hallmark—adularescence—is an optical interference phenomenon produced by light scattering (diffraction) between alternating microscopic sub-micron lamellae of orthoclase and albite feldspar within the crystal lattice. Under gemological examination, it exhibits a refractive index of 1.518 to 1.526, a specific gravity of 2.56 to 2.60, and a Mohs hardness of 6.0 to 6.5.

Cultural Legacy & Traditional Context: Celebrated historically in Hindu lore as frozen moonlight and revered in Indian lapidary traditions as Chandrakant Mani or Chandramani, Moonstone holds a sacred place in gemology. In Vedic astrology, it is the premier secondary substitute (Upratna) for Natural Pearl (Moti) associated with the Moon (Chandra). It is also recognized globally as an official June birthstone alongside Pearl and Alexandrite. It is customarily mounted in Sterling Silver (925 Silver) or Panchdhatu for rings and pendants.

Care Instructions

• Clean gently with mild soap and lukewarm water, then dry with a soft microfiber cloth.
• Avoid ultrasonic cleaners and steam cleaning; thermal shock and vibration can affect feldspar cleavage planes.
• Avoid contact with harsh household chemicals, strong acids, ammonia, and abrasive scouring pastes.
• For regular ring wear, a protective bezel setting is recommended, and the ring should be removed during strenuous activities.
