Non-diamond engagement rings are having a major moment. More couples are looking to unique, nontraditional engagement ring options that fit their individual lifestyle and taste. So it's no surprise there's been a noticeable surge in non-diamond engagement rings featuring precious and semiprecious gemstones, either in lieu of or in addition to diamonds. This cool girl trend has even infiltrated the Hollywood set: Celebs like Emma Stone, Katy Perry and Gwyneth Paltrow all rock alternative engagement rings with non-diamond center stones. 

There are so many beautiful, colorful and unique non-diamond engagement ring options, and choosing one definitely has its pros. One of the big ones? Gemstones are often less expensive than diamonds of comparable size (translation: you can probably get a precious or semi-precious stone of larger carat weight for a lower price point). And if you love the idea of wearing an heirloom ring, there's a treasure trove of vintage non-diamond engagement ring options to choose from (alternative engagement rings aren't just a trend—brides of all eras coveted non-diamond center stones too). As long as you do your research to find a reputable source, you can look for non-diamond engagement rings on Etsy or at a local vintage jewelry store.

What Are Non-Diamond Engagement Rings?

There's no shortage of non-diamond engagement ring options. Choosing the right one for you is simply a question of personal taste—after all, your engagement ring should be a reflection of your style. When it comes to non-diamond center stones, precious colored gemstones like sapphiresrubies and emeralds come to mind. (More on the benefits of sapphires and rubies in particular, below.) Otherwise, semi-precious stones like morganite, tourmaline, quartz, moonstone, topaz, garnet and opal—just to name a few—are right on trend. Another thought where diamond alternatives are concerned: synthetic options like  lab-created moissanite or other diamond simulants mimic the look and sparkle of a diamond, and are extremely budget-friendly. 

What Is the Best Alternative to a Diamond?

Diamonds have long been a symbol of commitment and eternal love, making them an obvious and coveted engagement ring stone (and don't worry, they're not going anywhere anytime soon). Beyond their radiance and romantic symbolism, they remain a popular engagement ring stone for more practical reasons: Diamond is the hardest material on Earth, ranking a 10 on the Mohs hardness scale.
Considering most people wear their engagement ring every day (often ignoring the advice to remove it when working out, gardening, cleaning and so on) their ring's durability is super important. With that in mind, if you're considering a non-diamond engagement ring, you'll want to know which gemstones look stunning and stand the test of time and everyday wear. You and your fiancé should study up on gemstone hardness and think about how you, personally, live your life and wear jewelry. For instance, do you hit the gym every day? Does your job require you to use your hands a lot? Are you constantly knocking your hands against things? If you answered yes to any of these questions, softer and more fragile stones like emeralds, pearls and opals may not be the best choice for you—but that doesn't mean there aren't equally fabulous options out there. 

Bottom line: If you're in the market for an alternative engagement ring but your lifestyle requires a sturdier center stone, consider a sapphire or ruby engagement ring. Ranking a 9 on the Mohs scale of mineral hardness, sapphire is one of the most scratch-resistant and durable materials after diamond. Kate Middleton's iconic sapphire engagement ring, made famous by Princess Diana before her, has definitely had a hand in sparking the blue sapphire engagement ring craze that just won't quit. Rubies also rank a 9 on the scale of hardness, because they're in the same gem family as sapphire, Corundum. This gorgeous crimson stone also has natural romantic associations, due to its rich, fiery hue.
