The Character of Moonstone
For centuries, Sri Lanka has been renowned as the 'Island of Jewels,' yielding some of the world's finest and most historically significant moonstones. Our deep-rooted connections with local artisanal miners allow us to source exceptional rough stones directly from the earth.
Each moonstone offered through IRIS Ceylon Gems is carefully evaluated by our master gemologists for its inherent beauty, optical phenomena, and enduring value. We prioritize natural, untreated stones that express the true character of Ceylon's unique geological heritage.
Notable Varieties
The moonstone family encompasses several distinct varieties, each valued for its unique optical properties and coloration.
Blue Sheen Moonstone
The classic and highly prized variety exhibiting a floating, billowy blue light (adularescence) over a clear or milky body.
Rainbow Moonstone
Technically a transparent variety of labradorite, it displays a striking, multi-colored schiller effect.
Cat's Eye Moonstone
A moonstone cut en cabochon that displays a sharp chatoyant band of light alongside its typical adularescence.
What to Consider
Colour & Saturation
The most valuable Ceylon moonstones are highly transparent with a strong, perfectly centered blue sheen.
Clarity
Look for stones free from prominent centipedes (stress cracks) that can disrupt the glow.
Cut & Brilliance
Must be expertly cut en cabochon to properly center the adularescence over the dome.
Treatment & Origin
Sri Lanka remains the world's premier source for authentic blue-sheen moonstones. To ensure complete peace of mind, every gemstone we offer is independently lab-certified by recognized gemological authorities.
