There’s the common phrase, “Diamonds are forever.” (Is anyone else now humming along to the Shirley Bassey song? 🎵) But while natural diamonds are made to last, they’re not always the most ethical option.
The majority of mined diamonds often come from war zones or areas facing massive conflict (you might be familiar with the term “blood diamonds,” which references the brutal origins of these stones). As a result, the popularity of lab-grown diamonds has increased over the past decade. With the same chemical makeup as natural diamonds and free from any conflict or environmental impact, these more affordable stones are a good alternative — but they remain fairly expensive and don’t come with a high resale value.
Moissanite, however, is an alternative gem that’s a fraction of the price — all with the same sparkle, brilliance, and durability (a 9.5 on the Mohs hardness scale vs. a diamond’s 10). While diamonds are pure carbon, moissanite is carbon and silica, which is why moissanite has a radiant rainbow refraction, too — swoon. 🌈 Moissanite was first discovered over a century ago on a meteor, and today it’s a beautiful lab-grown, cost-effective option for jewelry.
Whether you’re looking for some serious sparkle, hoping to find a colorless stone without breaking the bank, or just want to opt out of the diamond industry altogether, moissanite rings are a perfect choice, whether for engagement, everyday wear, or otherwise. We’ve selected the seven brands below based on their accessible pricing, customization options, and range of styles and sets — happy sustainable shopping! 💍
1. Brilliant Earth

Brilliant Earth is a popular go-to for ethical rings, but did you know that they also carry moissanite bridal sets? Instead of purchasing only an engagement ring or wedding band, get them both at an affordable price — aka one less step when you’re already overwhelmed with wedding planning! There are 120+ sets to choose from, but if that’s not your thing, you can also check out the nearly 350 moissanite ring styles instead. (As a heads up, most of the moissanite stones for the bridal sets are 8mm big.) Brilliant Earth is committed to being as eco-friendly as possible, leveraging recycled packaging materials, clean energy wherever possible, and donating to causes like climate action and responsible sourcing.

(Plus, if you love a specific stone or want a custom size, Gema&Co offers both of those services, too!) We appreciate the brand’s exceptional customer service — from the one-month window for returns, to the lifetime warranty, to insured delivery.

Then, the stones are set alongside conflict-free diamond halos or pave bands along a recycled metal band.
