7 Stunning & Ethical Diamond Alternatives for Unique Engagement Rings

Modern couples, especially millennials and Gen Z, are increasingly choosing sustainable and ethical options for their engagement rings, moving beyond traditional diamonds. While solitaire diamonds have long reigned supreme, many are now seeking the best alternatives to diamond engagement rings to reflect their values and individuality.

Furthermore, while lab-grown diamonds are sometimes discussed as ethical alternatives, at Jaume Labro, we don’t use artificial diamonds. Instead, we focus on natural, ethically sourced gemstones. Today, we present seven exquisite diamond alternatives for your engagement ring that offer unique charm and ethical appeal.

1. Garnets: a Versatile & Deeply Hued Diamond Alternative

While January’s birthstone is often associated with rich crimson, garnets boast a breathtaking spectrum of colors, from vibrant greens to clear, sparkling hues. This versatility makes them a captivating choice for a non-diamond engagement ring. One of the significant advantages of garnets is their natural clarity and transparency, often achieved without any enhancements. Furthermore, their impressive durability allows for various cutting styles, perfect for designing a flattering engagement ring setting for any hand. If you’re seeking an affordable engagement ring with a touch of vibrant color and excellent wearability, the garnet is a fantastic option.

2. Tsavorite: the Rare and Sustainable Emerald Alternative for Engagement Rings

Did you know that tsavorite is a vibrant green member of the garnet family? Discovered relatively recently in 1967, this gemstone has quickly become a fashionable and often more sustainable engagement ring option than traditional emeralds (and it’s even rarer!). Beloved for its dazzling depth of color, exceptional brilliance, and high durability, tsavorite makes for an unforgettable non-diamond engagement ring. Jewelers often showcase the stone’s sparkle with a facet cut, creating a truly eye-catching piece. For those mesmerized by the allure of green gemstones and are seeking a rare and ethically sourced stone for their engagement ring, a tsavorite engagement ring is an exquisite choice.

3. Amethyst: a Royal Purple Gem for a Unique Engagement Ring

From the softest lilac to the deepest violet, the captivating beauty of amethyst is undeniable. A significant benefit of choosing an amethyst as the best alternative to a diamond engagement ring is its resilience to daily wear and tear, making it suitable for nearly any cut and setting. Because amethyst is readily available in larger sizes and at an accessible price point, it’s ideal for designing a show-stopping yet affordable engagement ring. While February’s birthstone traditionally pairs beautifully with platinum and silver, we particularly love its warmth when set in rose or yellow gold, creating a truly unique and personalized piece.

4. Citrine: a Warm and Sunny Gemstone for Your Engagement Ring

In the past, citrine was often mistaken for yellow topaz, but today, it is celebrated for its durability, affordability, and radiant beauty. Typically found in warm shades of deep amber and sunny lemon yellow, these gemstones offer intense brilliance and fire at a fraction of the cost of yellow diamonds. Modern couples increasingly appreciate citrine as a vibrant and affordable engagement ring option. At Jaume Labro, our team has had the pleasure of designing a stunning non-diamond engagement ring featuring citrine, representing the joyful union of two souls.

5. Tanzanite: an Exotic and Individually Expressive Engagement Ring Stone

Prized for its vibrant blue to violet-blue hues, tanzanite is instantly recognizable and highly coveted by jewelry enthusiasts. Depending on the lighting and viewing angle, this pleochroic gemstone can display different colors, including deep sapphire blue under incandescent light and violet or purplish blue in daylight or fluorescent lighting. The most sought-after tanzanite exhibits an intense, saturated blue with a subtle violet undertone, often described as a mix between royal blue and lavender. 

Remarkably, this December birthstone is found in only one location in the world, near majestic Mount Kilimanjaro. Tanzanite has a hardness of 6.5 on the Mohs scale, so this stone can be cut into myriad shapes and sizes, allowing for truly unique designs. A tanzanite engagement ring is an exceptional choice for modern brides seeking an alternative to a diamond engagement ring that speaks volumes about their personality and individuality.

6. Opal: A Gem of Unmatched Character for Your Engagement

Mysterious, delicate, and utterly unique, opals have long been associated with magic and wonder. These fascinating gemstones display a mesmerizing play of colors with endless variations. Due to their delicate nature, working with opals requires an experienced stone-cutter, and we recommend protective channel or bezel settings. While October’s birthstone requires more care than some alternatives, an opal engagement ring, especially when paired with the unique patterns of Mokume Gane, remains a breathtaking and individualistic choice, well worth the extra attention.

7. Sapphire: A Timeless and Colorful Diamond Alternative

The deep blue color of a natural Ceylon sapphire is globally admired, famously adorning Princess Diana’s controversial engagement ring (now Kate Middleton’s). However, it’s important to remember that sapphires come in a stunning range of colors, including greens, pinks, yellows, and the coveted “padparadscha” (a beautiful orange rose hue). While around 99% of the world’s sapphires undergo heat treatment to enhance their color, untreated sapphires are highly prized for their rarity. Whether natural or treated, this durable gemstone can be cut and set into almost any style, making a sapphire engagement ring a truly timeless and versatile alternative to a diamond.
