Lab-Grown Eternity Rings: Endless Sparkle on a Modern Budget

Eternity rings have been around for centuries, but these days they're more than just a symbol of commitment, they're also a bit of a status symbol and—let’s be honest—just a really fabulous excuse to wear a whole lot of diamonds. Diamond eternity bands come in countless different shapes, styles, and sizes to suit every preference, whether you're wearing one as your wedding band, rocking it solo, or stacking them up for a more-is-more look that makes jaws drop.

The downside? More diamonds means a bigger price tag. But today, with lab diamonds, you can get all that shimmer without the sticker shock. Whether you tell anyone or not is up to you! But let's dive into what exactly makes eternity rings so iconic, and how a lab-grown eternity ring might just be the answer to your diamond prayers.

Stacked, solo, or paired with your engagement ring—eternity bands are the ultimate forever flex.

What is an Eternity Ring?

The concept of an eternity ring dates back to ancient Egypt, where circular bands symbolized eternity—no beginning, no end, just endless love (or in some cases, an endless appreciation for fine jewelry). The modern take on the eternity ring, featuring a continuous row of diamonds all the way around the finger, became popular in the 20th century and has remained a classic ever since.

Today, you can find eternity engagement rings, eternity wedding bands, and even eternity men's bands. Whether given as an anniversary gift, a wedding band, or a self-love splurge, eternity rings make a statement that never goes out of style.

More diamonds, less drama. Lab-grown eternity rings give you endless sparkle without the sky-high price tag.

Lab-Grown Diamonds (and Gemstones!) are the Future

If you love the look of a traditional diamond eternity band but want something more affordable, ethical, and just as brilliant, lab-grown diamonds and gemstones are the answer. These beauties are chemically, physically, and optically identical to their mined, natural diamond counterparts, but they come without the hefty price tag or environmental concerns. In fact, lab diamonds can cost nearly half of what natural diamonds cost! Lab-grown diamonds offer a more sustainable option while still delivering that jaw-dropping sparkle, making them perfect for modern couples who want modern design and luxury with a conscience.

And it’s not just diamonds—lab-grown gemstones like sapphires, rubies, emeralds, and even fancy yellow diamonds are making a bold statement in the jewelry world. Whether you’re drawn to the deep blue of a sapphire eternity ring, the fiery red of a ruby, or the vivid green glow of an emerald, lab-grown options give you all the color and brilliance of natural gemstones without the mining impact. Plus, they open up a world of design possibilities—think mixed gemstone eternity bands, ombré color gradients, or alternating diamonds and colored stones for a one-of-a-kind look.

Endless Ways to Shine

One of the best things about eternity rings? The sheer variety of styles! Whether you love a classic look or something unexpected, there’s a lab-grown diamond eternity ring out there for you.

• Petite & Thin Eternity Rings – Delicate and understated, a skinny eternity band is perfect for stacking with your engagement ring or layering with other bands for a customized look. These loose diamonds can be set into a variety of styles—pavé, bezel, bar-set, channel, etc.—it's really all about a thin line of sparkle.

• Prong-Set & Shared Prong Eternity Rings – The most classic eternity ring style, where larger diamonds sit side by side in a never-ending row of brilliance. The elegance of a shared prong setting maximizes the visibility of each stone for an ultra-sparkly effect. You can find a wide variety of total carat weights to choose from, along with different diamond shapes. Or you can mix diamond shapes in one ring!

• Bezel-Set Eternity Rings – For those who love a sleek and modern aesthetic, bezel-set eternity rings are crafted so that each diamond is surrounded by a thin metal rim, offering a clean, contemporary look with added security. Bezel set rings are great if you lead a more active life, so you don't have to worry quite so much about the security of your diamonds.

• Cigar Band & Wide Eternity Rings – Statement-making and bold, these rings feature multiple rows of diamonds or chunkier gold looks that create a big impact. Perfect for those who want to go all in on the bling. Keep in mind that the wider the ring, you may need a different finger size, so you might want to size up a bit.

• Unique & Alternative Eternity Rings – Think twisting bands, asymmetrical designs, or unexpected settings—eternity rings don’t have to be conventional to be meaningful (or stunning). The diamonds might be spaced at intervals, arranged in interesting patterns, look like a band of leaves around the finger, or any other idea you might dream up.

• Lab-Grown Colored Gemstone Eternity Rings – Who says eternity rings have to be white diamonds? Lab-grown sapphires, emeralds, and rubies add a splash of color, whether worn on their own or as accents to diamonds. You can also choose fancy yellow lab-grown diamonds for a high-fashion twist on timeless elegance.

Choosing the Perfect Metal for Your Eternity Ring

The metal you choose for your diamond eternity band is all about personal preference, but keep in mind that it can completely transform the look and feel of your ring. Some metals are warmer, some are more contemporary, and some are more vintage-feeling. What's your dream ring style and metal? Get some ideas below:

• Platinum – The ultimate in luxury, platinum is strong, naturally white, and hypoallergenic. It’s a fantastic choice for a timeless, high-end eternity ring that will hold up beautifully over time.

• White Gold – If you love the look of platinum but want something more budget-friendly, white gold is a great option. It has a bright, silvery appearance and pairs perfectly with lab diamonds for a clean, modern aesthetic. Just keep in mind that it may need periodic rhodium plating to maintain its shine.

• Yellow Gold – Warm, rich, and a forever classic, yellow gold gives eternity rings a vintage-meets-modern feel. It’s perfect for those who want a ring with a little extra glow and works especially well with fancy yellow lab-grown diamonds or colored gemstones.

• Rose Gold – Romantic and unexpected, rose gold adds a soft, feminine touch to eternity rings. Its blush tones make diamonds and gemstones pop, and it looks stunning on all skin tones.

Getting the Right Size: Why Eternity Rings Can’t Be Resized

One of the most important things to know before buying an eternity ring? They cannot be resized! Unlike traditional rings with a blank metal portion that allows for adjustments, eternity rings feature a continuous circle of diamonds or gemstones. That means if the size is off, there’s no easy fix—so getting it right the first time is crucial.

So how do you find your perfect size? Here are a few tips:

• Visit a Jeweler – The most reliable way to determine your ring size is to have a professional measure your finger for you in person. Any reputable local jeweler should be able to do this for you.

• Use a Ring Sizer – If you’re shopping online, consider ordering a plastic ring sizer or using a printable size guide to measure an existing ring.

• Consider Finger Swelling – Your fingers can change size throughout the day due to temperature, humidity, or even salt intake. Try measuring at different times for the best fit.

• Test With a Stacking Ring – If you already wear rings on the same finger, use one as a reference to find your ideal eternity ring size.

Taking the time to get your size right ensures your eternity ring fits comfortably and securely—because once it’s on, it’s meant to stay on forever!
