Onyx Engagement Rings: The Complete Guide

An onyx engagement ring is an excellent option for the bride-to-be looking for something unique and edgy. After all, has there ever been a more versatile neutral than black?

A distinguishing characteristic of onyx is its color. Onyx stones are most typically black with white bands. Though less common, onyx can also be found in green or reddish-brown called sardonyx. Fans of the ornate, antique looks of the Victorian era or the bold geometry of the Art Deco aesthetic may also want to consider an onyx engagement ring, as the stone was popular in both time periods.

“I recently had a bride come in who doesn’t wear jewelry very often,” says New York City jeweler Ashley Zhang. “To her, a diamond didn’t feel genuine. She didn’t want anything flashy. She wanted something unique and different. After looking at everything I had, she settled on an onyx ring because it was really simple, clean and modern.”

Pros and Cons of Onyx Rings

If you are looking for an edgy yet wearable alternative to a diamond, onyx is a great option. Colored gemstones have the potential to clash with everyday wear, while onyx remains fairly neutral with its black hue. "I'm not the biggest fan of color—maybe because I'm a New Yorker—and when you have an engagement ring, you should be able to wear it with everything," she says. "Onyx really lends itself to that, so you can do a lot in terms of styling." Not to mention, it's generally more affordable than diamonds.

Even though onyx makes for a one-of-a-kind, chic ring, the gemstone may not be for everybody. If you are looking for a glittering, brilliant stone for your engagement ring, onyx is not that. It is a much more low-profile stone that has properties different than a traditional diamond. Onyx is also a softer stone that has more potential for damage. That's not to say it isn't a stone for everyday wear. It might just require a bit more attention than more durable stones like diamonds and sapphires.

What to Look for in an Onyx Ring

• What setting works best with this type of ring? Zhang recommends to opt for a bezel setting for your onyx stone. “The bezel is a frame of metal around a stone,” she explains. “This is a smart way to set the stone, as when you hit the ring during everyday wear the metal will take most of the pressure.” This decreases the chance of the stone cracking or chipping.
• What shape works best with this type of stone? Since onyx is a softer gemstone it is able to be easily crafted into any shape! You will see it come in a variety of different cuts and shapes.
• How can I tell if an onyx gemstone is high quality? As with all engagement rings, you’ll want to work with a reputable jeweler you trust. Banded calcite, a less valuable mineral, and other stones can be dyed and passed off as onyx. Beyond that, Zhang says to look for scratches and chips on the surface of the stone, particularly if you’re considering a vintage ring.

How to Care for Your Onyx Ring

“Onyx is softer than diamond, but it is still an easy stone to care for,” says Zhang. “Steam or ultrasonic cleanings are safe, but you want to avoid extreme heat or chemicals. Soap and water is always safe and easy.”

The History of Onyx Gemstones

Per Zhang, the word onyx is derived from the ancient Greek word for claw. “The story is that while Venus slept, her fingernails were trimmed, and the gods turned these clippings into the stone known as onyx,” she says.

Throughout history, onyx has been used in protective amulets, rosaries, and cameos. During the Victorian era, it became a favorite stone in mourning jewelry. “The jewelry of this period reflected the monarch’s style,” says Zhang. “Queen Victoria expressed her sadness at the loss of her husband, Prince Albert, through her fashion choices.”

Today, onyx is associated with the Zodiac sign Leo and is also a traditional gemstone gift for 7th wedding anniversaries.
