2.325 Moonstone Blue Cabochon

This 2.325 carat Blue Moonstone is a great example of why this gemstone has been valued for centuries. Cut as a cabochon (a smooth, domed surface rather than faceted), it’s specifically shaped to highlight the stone’s most important feature—its natural optical effect known as adularescence.

You’ll notice a soft blue sheen that appears to move across the surface as the stone shifts in the light. This isn’t added or enhanced—it’s a natural phenomenon caused by the internal structure of the mineral. Higher-quality moonstones, like this one, show a more visible and concentrated blue flash.

With dimensions of 9.6 × 6.7 × 5.0 mm, this stone has enough depth to display that glow properly, which is something flatter stones often lack. It’s a practical size for rings or pendants and works well in both modern and traditional settings. This is the type of piece that shows what makes the material distinct—subtle at first glance, but much more interesting the longer you look at it.
