Rainbow Moonstone - Ovals

These Rainbow Moonstone cabochons are offered in two delicate sizes, both showcasing soft clarity with subtle, natural flashes of adularescence that appear as the stone moves in the light.

The larger size measures approximately 6mm by 7.5mm with a low profile height of around 1.8mm, giving a slim, refined silhouette ideal for fine detail work. These stones are mostly clear with gentle internal transparency, occasionally revealing soft blue or white flashes that drift just beneath the surface. Their minimal dome keeps them understated and elegant, perfect for fine stacking rings, small accent settings, or delicate cluster designs where multiple stones can be combined.

The smaller size measures approximately 4.5mm by 7mm with a height of around 2mm, offering a slightly more compact form. These are similarly clear, with intermittent flashes of adularescence that appear more subtly due to their size, giving a quiet, ethereal shimmer rather than a bold flash. They are well suited to fine earrings, micro-settings, or detailed decorative accents in more intricate jewellery pieces.

Together, both sizes offer a light, airy aesthetic — more delicate and understated than high-grade flashing Moonstone, but still carrying the soft glow and mystical character that makes this feldspar so loved in jewellery design.

Key Properties & Care

Rainbow Moonstone is a variety of Feldspar known for its soft glow and internal light effects.

Mohs Hardness: Rainbow Moonstone has a hardness of approximately 6 to 6.5, making it suitable for jewellery but requiring gentle handling compared to harder gemstones.

Cleaning: Clean carefully using warm soapy water and a soft cloth or brush. Avoid ultrasonic cleaners, steam cleaning, and harsh chemicals, as Moonstone can be sensitive to vibration and temperature changes.

Maintenance:
Durability: Moonstone has natural cleavage, meaning it can chip if struck sharply. These smaller, flatter cuts are less exposed but still benefit from protective settings.
Surface Finish: The polish enhances clarity and allows any internal adularescence to gently shift in the light.
Storage: Store separately in a soft pouch or lined jewellery box to prevent scratching from harder materials.
