2025 Engagement Ring Trends: The Hottest Styles for Lab-Grown Diamonds & Moissanite
When it comes to engagement rings in 2025, couples aren’t just buying jewelry — they’re making a statement. The conversation has shifted from what’s trendy to what’s meaningful, ethical, and uniquely you. This year, lab grown diamond rings and moissanite creations are leading the charge, offering beauty, brilliance, and conscience all in one sparkling package.
At Caratbazaar, we’ve spent years working directly with clients, inspecting stones under magnification, comparing cuts under natural light, and — yes — even wearing these pieces in real-life settings to see how they truly perform. That’s why when we talk about trends, we’re not guessing. We’re sharing what we’ve seen, held, and sold to real people making one of the biggest jewellery decisions of their lives.
Why 2025 Is the Year of Ethical Brilliance
Consumers today care about origin stories. They want to know not just what they’re buying, but where it came from and what it stands for. Lab grown solitaire diamond ring designs have become the go-to choice for couples who love the sparkle but don’t want the mining footprint. Moissanite, meanwhile, is proving it’s not just a “diamond alternative” — it’s a gemstone, known for fire, durability, and exceptional value.
Caratbazaar has seen a noticeable shift in our consultations: couples come in asking for specifics about stone grading, ethical sourcing, and long-term wearability before they even discuss price. It’s clear — transparency and trust are now as important as carats and clarity.
Trend #1: The Rise of the Lab Grown Solitaire
The solitaire isn’t going anywhere. In fact, it’s more popular than ever — but the 2025 version has a twist.
We’re talking lab grown diamond solitaire ring styles with modernized bands, unexpected prong designs, and even mixed metal shanks.
First-hand insight: A recent client of ours, a software engineer from Chicago, came in wanting “a stone that says elegance without ego.” She left with a 2.5 carat round brilliant lab grown solitaire diamond ring on a slim, slightly knife-edge platinum band. She told us later it got more compliments than she could count — and no one guessed it was lab-grown until she shared the story.
Why it’s hot:
- Timeless look with 2025 design upgrades
- Affordability without sacrificing quality
- Perfect canvas for customization
Trend #2: Statement Men’s Pieces
It’s not just about women anymore. Lab grown diamond men's ring styles are becoming a category in their own right — and they’re bolder than the discreet bands of the past.
We’re seeing thicker profiles, brushed finishes, black rhodium accents, and yes — full diamond settings. Moissanite is also making a huge entry into the male jewellery space, particularly for men’s moissanite rings that combine masculinity with brilliance.
Example from our workshop: One client wanted a heavy, squared-off lab grown diamond men's ring with channel-set stones that could hold up to his job as a chef. We built it in 14k white gold, tested it under kitchen conditions (steam, heat, repeated washing), and it passed with zero dulling.
Trend #3: Moissanite as the Centre of Attention
Five years ago, most buyers who chose moissanite did so quietly. Now? They’re proudly announcing it.
A moissanite solitaire ring delivers unmatched sparkle per dollar, and 2025’s designs are giving them luxury treatment: cathedral settings, intricate halo work, and even antique-inspired migraine.
Moissanite isn’t just about budget — it’s about personality. Its slightly higher refractive index gives off a rainbow fire that diamonds can’t quite match. Some love that extra dazzle; others prefer diamond’s whiter light. At Caratbazaar, we always show both under direct and diffused lighting so clients can see the difference in person.
Trend #4: Silver is Stealing the Scene
Silver is having a moment in fine jewellery, and moissanite is the perfect match. A silver ring with moissanite isn’t just affordable — it’s fashion-forward. In fact, younger couples (and those seeking a second, more casual engagement ring) are gravitating toward silver moissanite ring options for their modern, clean look.
We recently completed a custom silver moissanite ring for a couple in New York who wanted “a ring they could travel with” — something they wouldn’t stress over losing or damaging. The result? A bezel-set oval moissanite in sterling silver that turned heads in every vacation photo.
Trend #5: Side Stones and Storytelling
While solitaires still reign, moissanite side stone ring designs are emerging as a top request for 2025. Side stones can be symbolic — representing milestones, children, or shared dreams. They also add width and presence to a ring without increasing the centre stone size.
Pro tip from the bench: When pairing moissanite with side stones, match them carefully for cut and colour. Even a half-grade difference can show under certain lighting. At Caratbazaar, we hand-select matching stones so the flow from centre to side is seamless.
Trend #6: Mixing Metals and Textures
Gone are the days when an engagement ring had to match the wedding band perfectly. This year, mixed metals are everywhere — yellow gold shanks with platinum heads, rose gold under-galleries beneath white gold bands. It’s a subtle way to make even a lab grown diamond rings design feel one-of-a-kind.
We’ve also been experimenting with hammered, brushed, and matte finishes that contrast against the high polish of the prongs. This play with texture draws the eye to the centre stone and adds depth to the overall look.
Trend #7: Ethical Luxury Goes Mainstream
One of the biggest cultural shifts we’ve noticed. Couples openly choosing lab grown diamond rings or moissanite not just for price, but because they prefer the ethical story. There’s pride in saying, “We chose this because it’s sustainable and conflict-free.”
And it’s not just marketing. The technology for creating lab grown diamond rings has reached a point where the stones are virtually indistinguishable from mined diamonds to the naked eye. Combine that with top-tier craftsmanship and you’ve got heirloom-quality pieces that tell a story future generation can be proud of.
How to Choose Between Lab-Grown Diamonds and Moissanite in 2025
Lab-Grown Diamonds:
- Identical chemical makeup to mined diamonds
- Classic diamond “white light” sparkle
- Higher price than moissanite, but still less than mined
- Ideal if you want traditional diamond prestige without mining concerns
Moissanite:
- Even more sparkle due to higher refractive index
- Exceptional durability (9.25 on Mohs scale)
- Significantly more affordable per carat
- Perfect if you want size and brilliance on a budget
Real-World Buying Tips from the Caratbazaar Team
- View stones in natural light — Jewellery store lighting is designed to make everything sparkle. Take it near a window for the real-world view.
- Don’t ignore the setting — A perfect stone in the wrong setting can look lost. Match style to lifestyle.
- Ask about warranties and aftercare — Ethical choice also means long-term support.
- Consider finger shape and size — Wider bands suit longer fingers, delicate pavé suits smaller hands.
- Match metal to skin undertone — Cool undertones? Platinum or white gold. Warm? Yellow or rose gold.
Where the Trends Are Headed Next
If the first half of 2025 is any indication, the future is bright — and very sparkly. Lab grown diamond rings once considered “alternative,” are now firmly in the mainstream. Men’s moissanite rings are on the rise, silver is reclaiming space in fine jewellery, and mixed-metal designs are rewriting tradition.
At Caratbazaar, we expect to see even more personalization — hidden engravings, secret stones on the band’s underside, and settings built to hold heirloom stones from past generations. The message is clear: in 2025, your engagement ring should be as unique as your love story.
Conclusion:
An engagement ring has always been more than just a piece of jewellery. In 2025, that truth feels stronger than ever. The trends we’re seeing aren’t just about looks — they’re about meaning, values, and personal connection.
Couples today are choosing stones and designs that reflect who they are and what they believe in. For some, that means the elegance and tradition of a lab grown solitaire diamond ring — a timeless style with an ethical edge. For others, it’s the vibrant fire of a moissanite, set in a way that feels entirely their own.
What stands out this year is the creativity and individuality people are bringing to their choices. Mixed metals, textured finishes, hidden details, and custom accents are turning engagement rings into deeply personal keepsakes. We’re seeing pieces that not only symbolize commitment but also tell a unique story — one of conscious decisions, shared dreams, and lasting style.
At Caratbazaar, we’ve watched countless clients light up when they find the ring — the one that feels right from the moment it slips on their finger. That reaction has nothing to do with following a trend just for the sake of it, and everything to do with finding a piece that feels like it was made for them.
In the end, your engagement ring should be something you love now and decades from now. Trends will change, but a ring chosen with heart and intention will always remain in style.
