Moonlight Captured in Stone
Moonstone glows with a soft, floating light called adularescence — a billowy sheen that seems to drift just beneath the surface as the stone moves. Sri Lanka's finest moonstones show a magical blue sheen over a near-colourless, translucent body, and these are considered among the best in the world.
Moonstone is a variety of feldspar (hardness around 6–6.5). The shimmer is caused by light scattering between microscopic layers within the crystal.
A Famous Sri Lankan Source
Most of Sri Lanka's prized blue moonstone comes from Meetiyagoda, a small town near the south coast not far from Hikkaduwa. The mines here are a popular visit, and moonstone is one of the island's most affordable and beloved souvenirs.
What Affects Value
- Sheen colour — a vivid blue sheen is most prized; white/silver sheen is more common and affordable.
- Body clarity — a clean, transparent, colourless body lets the blue glow stand out.
- Cut — a well-domed cabochon centres the sheen.
Care Tip
Moonstone is relatively soft and can chip, so store it separately and avoid knocks. Clean gently with mild soapy water.
