Colored gemstones gain ground in engagement rings beyond diamonds

The engagement-ring center stone is changing first, and the money is following it. Diamonds still dominate the category, but the fastest-growing appetite is for color: pearls, sapphires, aquamarines, emeralds and rubies are showing up in more ring concepts, while retailers say buyers are using gemstone choices to signal individuality rather than defaulting to the old diamond script.

The numbers behind the shift

The diamond still holds the majority share, but the gap is no longer as absolute as it once was. The Knot’s 2024 Jewelry & Engagement Study says 83% of U.S. engagement rings use a clear diamond center stone, while 17% use something else. It also shows how many buyers are already moving toward mixed compositions: 51% of engagement rings in 2024 were described as having a clear diamond center stone with side stones and or accents, and 28% featured a round center stone. Among non-diamond precious-stone options, moissanite is the most popular alternative.

That matters because it suggests the market is not splitting cleanly between old and new. Instead, shoppers are still comfortable with diamond-adjacent looks, but they are increasingly willing to shift the center stone itself when the design feels more personal or when the price equation changes. The Knot also notes that diamonds were not considered the engagement-ring standard until the 20th century, which makes today’s color turn feel less like a revolt than a reset.

Why color is winning budget share

The clearest business case is difference. JCK’s June 2026 coverage from Las Vegas said color is increasingly the choice of bridal and fashion customers who want to stand apart from the crowd, and one dealer drew a stark contrast between a colored-stone ring at $20,000 and a natural diamond piece at $200,000. That is not just a style preference. It is a reallocation of ring budget toward something that reads as rarer, more personal, or simply smarter value.

Lab-grown diamonds have intensified that recalibration. JCK said some high-end clients who might once have chosen a large natural diamond are now reconsidering what feels special when large lab-grown stones are widely available at lower prices. WWD also found that shoppers are increasingly using Adobe Firefly’s engagement-ring design tools to visualize more gemstone-centered rings, a sign that the color shift is being designed digitally before it is bought physically.

This is why the trend looks more durable than a social-media spike. Social platforms and AI tools may have accelerated the discovery phase, but the underlying reasons are stronger than an aesthetic fad: Gen Z grew up personalizing everything, and retailers say color is selling itself rather than needing much persuasion. That points to a lasting demand shift, not just a momentary mood board.

Why sapphire keeps coming up first

Among colored stones, sapphire is the most convincing everyday engagement-ring candidate. GIA places sapphire in the jewelry trade’s Big 3, alongside ruby and emerald, and describes it as durable and available in most colors. It is also broader than many buyers realize: sapphire can refer to any corundum color except red, which is ruby.

That durability is the key to its market power. Sapphire has the hard-wearing profile people want for a ring meant to be worn daily, while still offering blue, pink, yellow, green and other looks that feel more distinctive than a white diamond. GIA’s quality guidance makes the point bluntly: color is the most important factor, and strong to vivid saturation matters.

Sapphire also arrives with cultural shorthand that buyers immediately understand. GIA identifies Princess Diana’s sapphire ring, now worn by Kate Middleton, as one of the world’s most famous engagement rings, and notes sapphire’s roles as September’s birthstone and the gem for the 5th and 45th anniversaries. That combination of wearability and symbolism helps explain why sapphire has become the easiest bridge between tradition and a more individual ring language.

The other stones gaining traction

The real expansion is wider than sapphire alone. WWD’s design data showed surging interest in pearl, sapphire, aquamarine, emerald and ruby center stones, and it also pointed to black onyx as part of the broader move away from the traditional diamond. JCK added bicolor tourmaline to the list of stones drawing attention, while its panelists said ruby engagement rings are selling well too, even though ruby sits at the expensive end of the colored-stone spectrum.

Each stone is carrying a different kind of value proposition. Pearls read softer and more romantic, emeralds and rubies feel richer and more editorial, and aquamarines bring a lighter, cooler palette that still signals intention. The common thread is not novelty for its own sake. It is the desire for a stone that says something specific about the wearer instead of repeating the most familiar luxury script.

How to judge a colored center stone without greenwashing

The strongest colored-stone claim is still the one that can be documented. For sapphire, GIA stresses that color, cut, clarity and carat all matter, and that treatments are common enough to ask about directly. Heat treatment, lattice diffusion and glass filler can all affect value, and stones with substantial glass filler require special care. If a seller describes a colored gem in dreamy language but will not say how it was treated, that is marketing, not transparency.

That scrutiny matters across the category, because the new engagement-ring market is being built on provenance as much as on beauty. Buyers are not simply rejecting diamonds. They are asking a more pointed question: if the center stone is the statement, what exactly is it saying, and is the story around it true? In 2026, that is where value is being renegotiated.
