Loose Rainbow Moonstone Gemstones with Blue Flash

Rainbow Moonstone for Jewelry

Rainbow Moonstone is a popular choice for rings, pendants and earrings due to its striking adularescence and romantic appeal. With a Mohs hardness of 6 to 6.5, it is best suited for jewelry with protective settings.

Blue Flash Rainbow Moonstone

The most desirable Rainbow Moonstone stones display an intense electric blue flash across the surface. The strength and coverage of this optical effect significantly influence value and appearance.

Rainbow Moonstone Cabochons

Cabochon cuts are especially popular because they enhance the stone’s natural sheen and floating light effect. Oval and round cabochons are ideal for statement rings and artisan jewelry.

Faceted Rainbow Moonstone

Faceted Rainbow Moonstone gemstones offer a brighter, more contemporary look. These cuts combine subtle sparkle with the signature internal glow of the stone.

Calibrated Rainbow Moonstone Sizes

We offer calibrated Rainbow Moonstone in common jewelry sizes such as 6 mm, 8 mm and 8 x 6 mm, making them easy to mount into standard settings.

I needed a very specific color of tourmaline and Gem Select had it. I had to get the client to agree and then ordered the stone. It arrived better than pictured and we all were very happy.

Always find more niche sizes/shapes as my unconventional designs require from this website. Recommending to fellow designers in the creative atmosphere on the usual, specially due to the quality and certification of gems.
