Rainbow Moonstone Rings

Light scattering between very thin layers inside the stone produces a flash that seems to float just under the surface. In rainbow moonstone it reads as a bright blue, often with violet or gold at the edges, and it moves as your hand turns. The effect shows best in a smooth, domed cabochon, which is why every ring here uses one.

No, and it is worth knowing before you buy. Rainbow moonstone is the trade name for white labradorite, a plagioclase feldspar related to classic moonstone, which is an orthoclase feldspar. The two share a milky body, a similar hardness and the same care, but rainbow moonstone has a livelier, more colorful flash. Every ring in this collection is rainbow moonstone. For true moonstone, the Floral Cabochon Moonstone Ring and the Diamond Stackable Moonstone Ring are in our moonstone jewelry collection.

No. The June birthstones are pearl, moonstone and alexandrite, and rainbow moonstone, being labradorite, is not on that list. These rings are chosen for their look rather than a birth month. If a June birthstone matters, choose one of the true moonstone rings above.

They need more care than most rings. Rainbow moonstone rates 6 to 6.5 on the Mohs scale, so it can scratch against everyday grit, and it can split along an internal cleavage plane if it takes a hard knock. Treat these as right-hand or occasion rings. Take yours off for the gym, gardening and household chores, and it will keep its polish for years.

Designs that surround or sink the stone. The Cabochon Dome Rainbow Moonstone Ring and the Dome Solitaire Rainbow Moonstone Ring hold the stone low in a rounded setting, so its edges stay out of the way. The Oval Diamond Halo Rainbow Moonstone Ring and the Round Diamond Halo Rainbow Moonstone Ring encircle the center with diamonds that take the knocks first, and the Cabochon Cluster Rainbow Moonstone Ring spreads the risk across several small stones rather than one large one.

Yes, and several are made for it. The Cabochon Stackable Rainbow Moonstone Ring, the Graduated Stackable Rainbow Moonstone Ring and the Diamond-Band Rainbow Moonstone Ring are slim enough to sit beside a plain gold band or each other. The Petite Diamond & Rainbow Moonstone Ring and the Diamond Rope Rainbow Moonstone Ring add a little texture to a stack. Keep the softer stone away from rings with tall prongs, which can scratch it over time.

Start with the Statement Cabochon Rainbow Moonstone Ring, the largest stone in the collection at 10x8mm and the broadest flash. The Round Diamond Halo Rainbow Moonstone Ring frames an 8mm center with a full circle of diamonds, and the Diamond Star Rainbow Moonstone Ring pairs the stone with a celestial motif that suits it unusually well. These are cocktail rings in spirit, best worn when the ring can be the focus.

Rainbow moonstone is generally sold untreated, and it is never dyed. Each product page states the stone details for that ring. Every stone has its own flash, and slight variation from one ring to the next is part of the character of a natural material.

Every style comes in 14K yellow gold, 14K white gold and 14K rose gold. White gold keeps the look cool and lets the blue flash read clearly. Yellow gold gives the milky body a warmer, candlelit tone and suits the rope and cluster designs particularly well. Rose gold is the softest pairing, a pretty choice with the star ring and the stackables.

Clean it with lukewarm water, a drop of mild soap and a soft brush, then dry it gently. Never put it in an ultrasonic cleaner or a steamer, both of which can widen tiny cleavage cracks in feldspar. Store it apart from harder stones and metal pieces that could scratch the dome, and have the setting checked once a year.

Order carefully, because each ring is made to the ring size you choose and is final sale. Our sizing guide explains how to measure, and a local jeweler can confirm the size in minutes. Dome and statement styles sit wider on the finger, so a quarter to half size up is often more comfortable.
