Diamond or Not? White Diamonds Aren’t the Only Gems for Unique Engagement Rings—Look to Natural Diamonds, Moissanite, and White Sapphire Rings Too

Engagements aren't just a matter of the heart. Don't get us wrong. We live for our clients' stories about finding each other and falling in love. (Seriously, tell us more. You met how???) But getting married can be a think piece all in itself, and your head might quickly start to spin when you think about big decisions, like choosing an engagement ring. When you visit one of our showrooms, in Philadelphia or New York City, to look at engagement rings, expect to have fun. But we're also ready to answer serious questions about ethics, sustainability and sourcing that you might have as you choose the right gemstone for you.

Diamonds are the most popular choice for engagement rings, but there are two other lovely colorless gemstones you can also consider: moissanite and white sapphire. We've made unique engagement rings using all three. Each can work for a couple who's thinking about how communities and the environment are impacted by gemstone mining.

  • Moissanite is a colorless gemstone that is produced in a lab, so there's no new mining involved.
  • For many Bario Neal diamond engagement rings, we use reclaimed diamonds. These are stones previously set in other jewelry, and buying reclaimed is the eco-friendliest choice. Not only do you avoid more mining, you're not tapping into the energy involved in lab manufacturing either.
  • We source our white sapphires from a family-run sapphire mine in Sri Lanka that works on a small scale and strives to have a light environmental footprint. If you buy a white sapphire engagement ring, you're supporting ethical small business owners and in turn their community's economy. Mining means jobs for the miners and financial stability.

Moissanite Engagement Rings

Even if chemistry class made you yawn, it's impossible to not be intrigued by a gemstone growing in a lab. Moissanite is actually a natural mineral, silicon carbide, though it's rarely found in nature anymore. A chemist, Henri Moissan, is credited with first identifying it, at the site of a meteor strike in Arizona in 1893. In the 1990s, some scientists (who probably did not fall asleep in front of their Bunsen burners in high school) figured out a way to produce the silicon carbide crystals that Moissan, when he first saw them, thought were diamonds. North Carolina-based, Charles & Colvard, filed a patent and started growing moissanite in a lab and selling the stones as an accessibly priced alternative to white diamonds. The company is Bario Neal's source for moissanite today.

If there's a giant stone in the perfect custom engagement ring design you have in your head, and budget is top of mind, a moissanite could be your go-to at about half the price of white diamonds. (A half carat diamond ring in a four-prong setting at Bario Neal retails for around $3,000. The same jewelry with a moissanite would start around $1,750.)

That accessibility has inspired some truly inventive collaborations with Bario Neal clients over the years, as you can see in this Custom Moissanite Cluster Ring. If you're ready to swear those are diamonds in that ring, well, you've got good company.

"Most people can't tell a difference between a diamond and a moissanite," says Genna Fischer, Bario Neal gemstone sourcing coordinator.  

Diamonds and moissanite are so twinning, you can easily mix them in a stack, or even in the same ring. The double-take proof is in this Custom 2-carat Oval Moissanite Cluster Ring with Diamonds.

At larger sizes, moissanite does tend to throw off rainbow vibes when sparkling, whereas a white diamond has a truer white/silver sparkle. Moissanite is nearly as hard as diamonds (at 9.5 on the Mohs hardness scale vs. a diamond's 10) so they're completely durable for a daily wear ring. If you're passing on diamonds altogether but want smaller stones in your wedding band or encircling your center stone, moissanite comes in tiny melee sizes too.  

Diamonds have been the stars of engagement rings for decades and big marketing bucks go into generating a mystique around them, but we think moissanite has its own story to tell as unique-to-the-lab stones.

Two Bario Neal clients who happened to be scientists agreed. As a nod to their shared profession, they chose moissanite for this Custom Moissanite Linear Cluster Ring. Catalyst Wedding Co. called the engagement ring "seriously one of the coolest ideas we have heard."

Sapphires are most famous in blue, but a white sapphire is another tempting and colorless gemstone for engagement rings, especially if you want a white diamond look without the diamond.

"White sapphires tend to have a bit more of a gray-blue undertone than a diamond, and you can see that," Genna says. "A white sapphire looks different from a diamond or a moissanite. It's its own thing. It's more understated."

We're all for everyone being their own thing, so maybe that's why white sapphires get us every time. There's nothing not pretty about those undertones either, as you can see in our Custom Trillion Cut White Sapphire Bouquet Cluster Ring. There's a reason that our Trillion Dyad Ring and its white sapphires stop wedding bloggers in their tracks.

Like moissanite, white sapphires are also more accessibly priced than white diamonds. They bring a less fiery but no less inviting look to an engagement ring, such as our Nikko Pear White Sapphire Ring.

"White sapphires don't have the across-the-room flare of diamonds, which make them a budget-friendly option for someone who wants a colorless gemstone that's subtler and less sparkly," Genna says.

By using reclaimed white diamonds, heirloom diamonds, and Canadian-mined white diamonds, Bario Neal maintains high standards about ethics and sourcing and gives our clients plenty of diamond engagement ring choices.

Our Quince Diamond Ring might not look guilt-free, but it is, right down to the tiny diamonds in the halo. Many jewelers can't assure that such small stones, called melee, are ethically sourced, but Bario Neal makes sure ours are 100 percent traceable and ethical. (For a complete takedown of diamond myths, check out our helpful guide to diamond facts.)

If you're looking for a true antique cut in a reclaimed gemstone, look to diamonds. The 1990s-born moissanite and more newly popular white sapphires come primarily in modern-day cuts.

Raw Diamond Engagement Rings

Raw diamonds bring a more rugged or natural look to an engagement ring. While you might be well aware of the harm that mining can bring to people and the environment, there's, unfortunately, room for abuse in the processing of stones too. Unfair labor practices are connected to cutting and polishing diamonds in many places. Bario Neal's ethical jewelry standards mean that we fully trace our gemstones as they make their way to us, so if you're buying from us, you can trust that's not the case for your engagement ring. Still, raw diamonds have their own aesthetic appeal, and their shape and appearance open up different setting designs with a natural glimmer.

Raw (or rough) diamonds in an engagement ring make for a quiet contrast between delicate and tough in our Avens Raw Diamond Ring and our Kalmia Raw Diamond Ring. If you prefer cluster to a solo look, look at our Avens Asymmetrical Raw Diamond Ring, which puts a raw diamond with sapphires.

We know you've got the heart part of this engagement ring business down. We're here to help you sort through details like gemstones, metals, design, ethical sourcing and sustainability.
