We’ve spent the past ten years researching and wearing ethically sourced jewelry. These are our picks for conflict-free sapphire and diamond rings made with sustainable materials to stand the test of time.
Princess Diana deserves credit for cementing sapphire and diamond rings in sartorial history. Her engagement ring, now worn by her daughter-in-law Kate Middleton, features a 12-carat Ceylon sapphire surrounded by a 14-diamond halo. You can easily find sapphires that match the same deep blue as Princess Diana’s, but the gemstone comes in hues of green, orange, pink, and purple. White sapphires are even lower-cost alternatives to diamonds. 💍
Sapphires and diamonds are a perfect combination for engagement rings and other jewelry, but it’s important to know where they come from. When gemstones aren’t traceable or ethically sourced, it could be tied to unsafe working conditions and unfair wages, environmental concerns, and funding corruption.
To navigate this sometimes sticky and overwhelming shopping process, we narrowed it down to nine brands putting in the work to ensure your jewelry is conflict-free and made with sustainable materials and methods. Below, review the best sapphire and diamond rings, including options with lab-grown or traceable gemstones, responsibly mined and recycled materials, and at a range of price points.
Why consider sustainable, ethical sapphires?
Sustainable jewelry is a response to more traditional jewelry production, which is associated with exploitative labor and environmental harm (among other concerns). In other words, you can feel better knowing your new piece of jewelry comes from a brand that prioritizes responsibly sourced materials and workers’ rights. Seeking out jewelry brands and companies that are Fair Trade Certified or part of the Kimberley Process Certification Scheme is a good sign that your ring or other jewelry item is both sustainable and ethical.
While any jewelry item can be beautiful, some come with harrowing backstories. Thankfully, several companies have a clear conscience in their business practices and offer transparency about how they protect workers and the environment throughout the sourcing and manufacturing process.
What should you look for when buying a sapphire and diamond ring?
There are several factors to review before you commit to “the one.” Here’s the need-to-know information for anyone making such a big purchase:
- Sourcing of materials: Companies may recycle or repurpose gemstones and metal from old jewelry, source natural diamonds and sapphires from suppliers with ethical mining practices, or reproduce gemstones in a lab.
- Quality of the gemstones: Your jewelry’s craftsmanship is only as good as the materials used. Pay attention to the 4Cs of diamonds and other gemstones (cut, clarity, color, and carat), but prioritize color for sapphires.
- Sustainability efforts: Beyond the materials in the product, we look for brands that also make their packaging sustainable with recycled or recyclable materials, cut out middlemen in shipping, or keep inventories low to reduce waste.
- Durability: High-quality, long-lasting products are significantly better for the environment. And at a time when fast fashion is convenient yet deeply troubling for resources, durability is where quality overrules quantity.
- Overall design: Modern-minimalist, vintage-inspired, and everything in between. After considering materials and quality, choose a design that fits your personal style.

1. Brilliant Earth
Best For | Wide range of designs
Gemstone sourcing | Traceable natural gemstones, lab-grown gemstones, fair trade, Beyond Conflict Free standard
Prices starting at | $990
For Brilliant Earth’s origin story, we have to go back to the early 2000s. In 2004, co-founder and CEO Beth Gerstein went on a personal, almost impossible quest to find a sustainable engagement ring—and started Brilliant Earth to make the process easier for others (and better for the world). Founded in 2005, Brilliant Earth has spent the past 20 years perfecting its craft of made-to-order, conflict-free jewelry. With traceable natural diamonds and sapphires, or lab-grown gemstones, you’ll find plenty to choose from in their extensive inventory. Plus, almost all the metal they use is “repurposed,” and their goal is to have 100% of their metal repurposed or Fairmined in 2025.
Whether you want a diamond solitaire flanked by two sapphires or a band creating a pattern with the two gemstones, you’ll have plenty of combinations to review before deciding. On Brilliant Earth’s easy-to-use website, you can shop by gemstone color, shape, or type, then complete your ring with the setting. With Brilliant Earth’s build-your-own designs, you can choose a specific set or create a unique design on their website, through a virtual appointment, or at one of their showrooms.
Customer Review | “We selected this ring as a wedding band because I wanted something different than just diamonds. The sapphires are a beautiful addition and it’s especially sparkly against the yellow gold. It’s comfortable to wear and can be stacked with other bands/rings. I really love it!” – Rana (Read more reviews.)

2. Aurate
Best For | Princess Diana reproduction ring
Gemstone sourcing | Kimberley Process-cleared diamonds, lab-grown gemstones
Prices starting at | $108
Started in New York City by two grad school friends who wanted to curate a collection of high-quality, moderately priced jewelry, Aurate is a win for your budget and the environment. The team hand-picks gemstones and highlights recycled gold and sustainably harvested pearls as part of their environmentally conscious efforts. These feel-good practices extend to their charity work, as they give back to support education, women’s empowerment, and entrepreneurship through partnerships with Mastery Charter, She Should Run, and Build NYC.
Most of their gemstone rings are under $300, so they’re great for anyone who wants a lower-cost ring with a luxe look and feel. In fact, the brand has an entire collection called the “Diana,” which includes a reproduction of the iconic royal ring. The brand also offers customizable toi et moi rings, an on-trend style featuring one sapphire and one diamond. French for “you and me,” this ring style doesn’t let one gemstone steal the spotlight. Instead, it makes room for two — a swoon-worthy concept for an engagement ring or any gift to a loved one.
Customer Review | “This ring is so delicate and pretty. I love the unusual orientation of the stones in the vintage setting. It rests very gracefully on my finger. I get many compliments on it.” – Janis W. (Read more reviews.)
3. Bario Neal
Best For | Sapphire cluster rings
Gemstone sourcing | Traceable gemstones, repurposed recycled or lab-grown diamonds
Prices starting at | $1,200
Bario Neal was founded in Philadelphia in 2008 by designers Anna Bario and Page Neal, who wanted to create a collection with sustainability and inclusivity in mind. The result? The most expansive sizing collection, featuring gender-inclusive designs and customizations to make jewelry that’s wonderfully original. Most of their diamonds are recycled and from Canada or Australia, or lab-grown, and gemstones such as sapphires are high-quality and traceable. They use only Fairmined and recycled metals, and their eco-friendliness extends to their packaging.
We love the unexpected blend of diamond and sapphires in this cluster ring, and you might not realize which is which. The champagne diamond and white sapphire create a whimsical, delicate conversation starter. A cushion-cut diamond is also flanked by clusters of yellow and apricot sapphires. These are handmade and made to order, so expect several weeks for production, though rush services are available.
Customer Review | “Absolutely love this business! I stumbled on Bario Neal on a recent trip to Philly and their rainbow charm caught my eye. As soon as I entered, I was warmly greeted and able to browse leisurely before inquiring about the charm. I was told that the profits went to a local youth organization, and we had a lovely conversation about the history and mission of BN. I will absolutely go back every time I am in Philly, and already have my next piece picked out. Make sure you stop in if you have a chance – the people and wonderful and their pieces are unique, diverse, and gorgeous.” – Kellie W. (Read more reviews.)
4. Quince
Best For | Lab-grown sapphire diamonds
Gemstone sourcing | Lab-grown diamonds
Prices starting at | $548
We love Quince for making sapphire and diamond jewelry more accessible, with a growing selection of pieces in 14k white and yellow gold and lab-grown sapphire diamonds. Quince works directly with audited partner factories and uses a factory-direct model that cuts out traditional retail middlemen, which helps keep prices lower.
We also appreciate Quince’s focus on responsible production. The brand says it partners with factories that meet its standards for safe working conditions and fair wages, and some of its jewelry is sourced from Responsible Jewelry Council members with traceability standards. Quince ships directly from its manufacturers and says it uses compostable poly bags and recycled plastic mailers to reduce packaging waste.
Customer Review | “Love this beautiful ring. The diamonds are really sparkly and frame the sapphire well. Love the deep blue of the sapphire. The gold band is surprisingly sturdy give how thin and delicate it appears. A great blend of a minimal and statement piece all in one.” – Jennifer T. (Read more reviews.)
5. Linjer
Best For | Delicate sapphire rings
Gemstone sourcing | Lab-grown diamonds, ethically sourced gemstones
Prices starting at | $699
Jennifer Chong and Roman Khan were troubled that they saw only two routes in the industry: fast fashion or luxury brands. So, the couple merged the two and founded Linjer in 2014, promoting high-quality materials with a direct-to-consumer model to avoid hefty markups. The brand says all its jewelry is made with recycled materials, ethically sourced gemstones such as blue sapphires, and conflict-free, lab-grown diamonds identical to natural diamonds. To further promote sustainability, Linjer makes its jewelry with 100% recycled gold and silver, packages and ships with recycled materials, and offsets carbon emissions for every shipment. The Sapphire Half Eternity Ring features five pear-cut blue sapphires and four round white sapphires, mimicking the classic sapphire-and-diamond combo. (And you can complete the look with the brand’s sapphire and diamond earrings.) For a more budget-friendly alternative to blue sapphires, Linjer offers several topaz jewelry items in two shades of blue.
6. Mejuri
Best For | White sapphire diamond rings
Gemstone sourcing | Lab-grown gemstones, ethically sourced natural and lab-grown diamonds
Prices starting at | $198
Mejuri’s jewelry collection is effortlessly chic and cool, featuring several rings with white sapphire gemstones. In 2023, they launched the Social and Environmental Accountability (SEA) Program to “continually evaluate our suppliers and practices,” according to their latest sustainability report. With these trusted partners on board, they use both natural and lab-grown diamonds, and 99% of their precious gemstones are traceable. To reduce waste, they release new jewelry items in limited quantities. And to champion future generations and promote women’s empowerment (among many other causes), Mejuri has developed scholarship programs and created special products that give back.
If you’re on a mission to find white sapphires, Mejuri is your one-stop shop for lower-cost diamond dupes. They don’t offer sapphire and diamond rings, but we were wowed by the under-$200 rings with white sapphires. Unique eternity rings and metal-forward nesting rings are only a couple of examples from the extensive collection. Though many companies guarantee their gemstones are ethically sourced, Mejuri goes a step further by ensuring they’re 100% conflict-free with lab-grown sapphires.
Customer Review | “I had heard about Mejuri online and finally had the chance to visit a store. I had an amazing time with the staff who were very friendly and very helpful in choosing the ring of my choice. It has been 2 weeks since purchase and I am loving every compliment, wear and feel of this ring on my finger! Highly recommend in the investment in purchasing a Mejuri ring!“ – Seiko I. (Read more reviews.)
7. Etsy
Best For | Customizable or vintage rings
Gemstone sourcing | Ethically sourced gemstones, Secondhand materials
Etsy is a hub for creatives, and its jewelry section is one of our editors’ favorite destinations during online shopping sprees. There are near-countless sellers, many of which emphasize their sustainability and ethically sourced materials. Unlike other jewelry brands, Etsy has so much to review that you’ll want to take your time and explore top-rated shops. For instance, we often turn to Estate Antique Jewelry for secondhand, vintage pieces, but there are also plenty of modern options from artisans like Sarah of Sarah Elise Jewelry.
Customer Review | “I ordered 2 of the sapphire rings. Absolutely beautiful. Exceptional quality and workmanship. Will definitely purchase from her again!” – Apple User (Read more reviews.)
