If you're contemplating a colorful sparkler, a sapphire engagement ring is a timeless choice. It's no wonder sapphires have been one of the most popular precious gemstones for centuries—they're a gorgeous "something blue," with lots of sentimental meaning and they're totally on trend. In fact, The Knot's 2022 Jewelry and Engagement Study shows they're one of the most popular colorful center stones, making up 15% of non-diamond engagement rings. Sapphires also just so happen to be one of the British royal family's engagement ring go-tos. After all, Kate Middleton's stunning 18-carat, blue sapphire engagement ring was originally presented to Princess Diana, and is perhaps one of the most famous pieces of jewelry in the world.

What is a sapphire, exactly? Sapphires belong to the corundum family of minerals and were once considered one of the "Big Four" of precious jewels, alongside rubies, emeralds and diamonds. On a more technical note, these durable stones appeal to jewelers because they have a hardness of nine on the Mohs scale (diamonds are a 10). So, if you're looking for a sturdy gemstone that stands out from the crowd and has a rich history, a sapphire might be for you. Read on for everything you need to know about sapphire engagement rings, including editor-approved styles you can shop now.

Sapphire Engagement Rings Meaning

The meaning behind sapphire engagement rings goes way, way back. "Sapphires have been treasured for more than 2,500 years," says Greg Kwiat, CEO of Kwiat Diamonds and Fred Leighton. "Although they can be found in a range of colors, we generally think of them as blue—and it is blue sapphires that have been symbolic of royalty and romance, from Ancient Greece and Rome through the modern era." In ancient cultures, sapphire talismans were thought to have strong medicinal and protective powers because their blue color symbolized the heavens. A representation of honesty and wisdom, sapphires soon became the preferred gem of medieval royalty and clergy. Kings even wore them when they signed treaties as a symbol of good luck.

"Engagement rings used to only be for the royal and wealthy and were made of many different gemstones, including sapphires, before the diamond became the standard stone we use now," says Ashley Zhang, founder of Ashley Zhang Jewelry. "Some of the most famous sapphire engagement rings in history are Emperor Napoleon's diamond and sapphire toi et moi style ring for his wife Josephine, and of course Princess Diana's ring." In modern day, sapphire engagement rings are associated with fidelity and good luck. "It is said that sapphire engagement rings bring honesty and loyalty, as well as good fortune to the couple. It's a symbol of purity," says Yvonne Léon, founder of Yvonne Léon jewelry.

Sapphire Engagement Ring 101

Are Sapphires Good for Engagement Rings?

Yes, sapphires make good engagement rings. Unlike some other gemstones, which can be soft and easily damaged, sapphires are almost as hard as diamonds and will stand up to the wear and tear of everyday use. They're also an instant conversation starter, thanks to their color variety (more on this below). "Sapphires stand out and make a statement instantly, whether it's a one-carat or a five-carat stone," says Ali Galgano, founder of Serpentine Jewels. "Whereas with a white diamond, it's a little bit harder to get that overall knockout look without spending more on a larger stone. Plus, getting engaged with a colored stone is something that is not so commonplace these days, and will really allow someone to have an engagement ring that's incredibly individualized." Another pro? Sapphires are available in a wide range of settings, so you can easily find one that speaks to your personal style without having to go the custom route.

What to Look for in a Sapphire Engagement Ring

Color: The most significant factor in a Sapphire's price is its color. Natural, untreated pure blue Sapphires are the rarest and most valuable. However, they also represent a very small portion of the market. If you aren't on the hunt for a priceless stone, we recommend choosing the sapphire that appeals to you. They come in a wide spectrum of colors, each with their own significance. Are you classic? A traditional deep blue sapphire might be right for you. If you're going for edginess, consider an orange, green or gray option. Meanwhile, hopeless romantics will love the dreamy look of peach, pink and light purple sapphires. The choice is yours—just make sure you see the stone IRL before you purchase (or get very detailed photos) and you're happy with how it looks against your skin tone.

Cut: Like diamonds, sapphires come in pretty much every shape. The most popular ones are round, oval and cushion, as these tend to show off their color best. Whatever shape you choose, it's important to pick one that's cut symmetrically, is well polished and reflects the light evenly. Our advice? Working with a professional jeweler will help to ensure you're getting the best quality stone possible.

Setting: While the center stone is the focal point of your engagement ring, the setting determines its overall style. Sapphire engagement rings are available in almost every setting imaginable, so it's important to choose one that speaks to you.

Origin: Many vintage and antique rings have sapphires, as they were once more commonly used for engagement rings than diamonds. If you purchase an estate piece, have your jeweler check the security of the stone (or accent stones) once in a while—prong settings in particular can loosen over time.

Different Colors of Sapphires

If a blue sapphire ring isn't your thing, don't fret. While blue sapphires are the rarest and most valuable, this gorgeous gem actually occurs in a rainbow of hues—and other colors tend to be more budget-friendly. Where a sapphire comes from can actually influence its color, as is the case with the trendy Montana sapphire. What is a Montana sapphire? Simply put, a Montana sapphire is one that comes from the state of Montana. These stones are known for their distinctive hues of light pastels, teal and smoky gray, as well as more sustainable and ethical mining practices.

Below, find a list of colors sapphires come in. Fun fact: Red is noticeably missing because a red sapphire is called a ruby.

    Where to Buy Sapphire Engagement Rings

    With any engagement ring purchase, it's important to buy a sapphire engagement ring from a professional jeweler. Get recommendations from family and friends or, check for retailers with an industry organization affiliation. Stores accredited by the Gemological Institute of America (GIA) the Jewelers of America or members of the are good places to start. And always find out what a store's return policy is. You want to be able to at least exchange the engagement ring or loose stone if it's not the one you want—especially if you're purchasing online and not in person. Some established retailers we trust include Kwiat Diamonds, Blue Nile, Brilliant Earth and Gemist, as well as any of the jewelers listed below.

    Are Sapphires Cheaper Than Diamonds?

    Sapphires are less expensive than diamonds—with some exceptions. A sapphire's value (and thus the cost of a sapphire engagement ring) is primarily based on the strength of its natural color; the more vivid a sapphire's natural hue, the more expensive it is. Frequently, sapphires are treated with heat to enhance the richness of their color. Naturally vibrant sapphires that don't require any heat treatment will command a premium price, but they're also very hard to find. "Sapphires come in a wide range of qualities, colors and treatments," says Burak Tirtirian of CICADA jewelry. "Natural, unheated sapphires in rare colors can be much more expensive than diamonds, whereas smaller, heated sapphires tend to be less expensive than diamonds." TLDR; most of the sapphires available to consumers are less expensive per carat than diamonds, unless you're opting for an extremely rare, unheated stone.

    In fact, if you love the look of a white diamond but are on a budget, a colorless sapphire (also called a white sapphire) is a great diamond dupe. The same goes for yellow and pink sapphires, which won't cost you nearly as much as their colorful diamond counterparts. "A sapphire engagement ring offers the opportunity to get a ring that isn't so expensive but still feels really special, large and has a rich, well-respected history," Galgano says.

    How to Clean a Sapphire Engagement Ring

    Though sapphire rings are almost as durable as diamond rings, they still require special care. "Most things that you can do with diamonds you can do with sapphires," Galgano says. "I recommend that people clean their diamond or sapphire jewelry with either an ultrasonic machine or a toothbrush and a touch of dish soap." It's also a good idea to take your sapphire ring to a jeweler for an in-depth cleaning at least once a year—you'd be surprised how much grime can build up over time and dull your sparkler!
