Rainbow
Rainbow here means opal. Raw Australian fire opal with its green, orange and blue flashes, and lab-grown Kyocera opal cut into stars, moons and butterflies.
Star and moon rings, cluster studs, hero opal bracelets and, at the top of the range, the Chromia raw opal waterfall earrings. Rough opal is graded and set by hand, so the color play shifts stone to stone and no two look quite alike.

What to expect from your Rainbow
Stones, metals, delivery windows, sizing and daily wear, gathered in one place.
Why is every raw stone different?
Each stone is a genuine raw gemstone, kept in the shape it grew in rather than cut and faceted. Colour, shape and inclusions shift from one crystal to the next, so no two pieces are identical and the one that arrives is a close relative of the photo rather than a copy. Every gemstone we set is conflict-free.
What are these pieces made of?
Gold styles are 14k gold-filled (1/20) finished with a 24k gold dip, warm pink styles use rose gold fill, and any style listing a silver option is made in 925 sterling silver. Gold fill is a thick bonded layer of gold rather than a thin plating, which is why it stands up to daily wear. We use recycled precious metals wherever possible, and every piece is 100% hand crafted in our Atlanta studio by Bailey.
When will my order reach me?
Shipping inside the US is free on every order with no minimum, and each parcel travels with tracking. In-stock pieces ship within 1 business day and land in 3 to 5 days, while made-to-order pieces are handcrafted within 10 to 15 business days before they ship. International orders travel at USPS rates, and any duties are the responsibility of the buyer.
What if I need to send something back?
Unworn pieces can come back to us within 100 days of delivery, with custom and made-to-order work as the two exceptions. Return postage is paid by the buyer unless the mistake was ours. Write to support@ringcrush.com and we will walk through it with you.
How do I land on the right ring size?
Sizes are listed on each ring page, and ready-to-ship rings are made in whole sizes. Every ring page carries a size guide plus a printable paper sizer you can measure with at home. If you sit between two sizes, take the larger of the two.
How do I keep a piece looking its best?
Keep it clear of chlorine, harsh cleansers and household chemicals, and slip it off before you swim. A soft dry cloth is all it takes to buff the metal back up. Store it dry and out of direct sun, and the Ringcrush gift box that comes with every order at no extra charge is a good place for it.
A closer look at Rainbow
Opal carries water inside its structure, and the microscopic spheres in that structure are what split light into the shifting colors collectors call play-of-color. Australian rough is the source for the raw pieces here; the Kyocera stones are lab-grown, consistent in pattern, and a practical choice for the star and moon shapes. All of it… is set in 24k gold over electroformed copper or on 14k gold-filled (1/20) chain with a 24k dip, assembled in our Atlanta studio. If you want opal you can wear daily, a small stud or a mini ring keeps the stone protected. If you want the color to be the point, go up in size to a cluster or a two-stone pendant. Opal is the October birthstone, which makes this a natural place to start a fall gift.
