Green Moonstone

Green Moonstone is a variety of moonstone, the feldspar gem famous for adularescence, with a soft greenish to greenish-gray body color. The gentle green tint, sometimes described as pistachio or minty, sets it apart from the more familiar white and rainbow moonstones.

Like all moonstones, its characteristic feature is a billowy, glowing sheen that appears to float beneath the surface and moves as the stone is turned. The body color is usually subtle, with the adularescent glow giving the stone its life.

Green moonstone is commonly sourced from India and is popular as an affordable, calming gemstone in both fine and artisan jewelry.

Green Moonstone forms as feldspar crystallizing in igneous rocks such as pegmatites and granites. During slow cooling, the feldspar separates into microscopic alternating layers of two compositions (exsolution lamellae); light scattering from these layers creates the adularescent sheen.

The faint green body color results from trace elements and inclusions within the feldspar. Much green moonstone comes from India, with other feldspar moonstones produced in Sri Lanka, Madagascar, and elsewhere. As with all moonstone varieties, the quality of the sheen depends on the fineness and orientation of the internal layering and on cutting the stone to display the glow to best effect.

Green Moonstone is a feldspar of Mohs 6-6.5 with two cleavages near 90 degrees and a vitreous to pearly luster. It shows a pale green to greenish-gray body with a soft white or bluish adularescent glow that shifts when tilted; the streak is white.

The sheen is a gentle floating light, not the spectral flash of labradorite or the sparkle of aventurine. The greenish body color is usually muted.

Distinguish it from green aventurine (quartz, sparkly from mica/fuchsite inclusions, no adularescence) and from prehnite or chrysoprase (different hardness, no billowy sheen, no feldspar cleavage). Dyed or glass imitations lack the genuine internal glow and feldspar cleavage.

Green Moonstone is used as a gemstone, cut into cabochons, beads, and freeform shapes for rings, pendants, bracelets, and earrings. Its soft color and soothing sheen make it popular in both everyday and bohemian-style jewelry, and it is generally affordable.

Value depends mainly on the quality and color of the adularescence and the appeal of the body color. As a feldspar with cleavage, it benefits from protective settings and gentle care.

In metaphysical traditions green moonstone is associated with calm, growth, intuition, and emotional balance, often linked to nature and the heart; these are traditional beliefs rather than scientifically proven properties.
