Top 7 Engagement Ring Trends with Lab-Grown Diamonds in 2025

October 30, 2025

Engagement rings aren’t just rings any more. They’re statements — of love, of personality, and of values. For the modern couple, choosing an engagement ring is as much about style and meaning as it is about sparkle. With the rise of lab-grown diamonds, the playing field has shifted: you can get better size, better ethics, and better value. In this article we present the top 7 engagement ring trends for 2025, all compatible with lab-grown diamond jewellery — plus styling tips, what to watch for, and how your brand can help customers stay ahead of the curve.

Trend 1 – Minimalist Solitaire Rings: Timeless Yet Sustainable

The solo diamond ring remains a classic — but in 2025 the twist is sustainability. Many couples are opting for a single, high-quality lab-grown diamond set in a clean, modern band (white gold, platinum or yellow gold). The focus is on the diamond’s size and quality rather than heavy ornamentation. The advantage of lab-grown here: for the same budget you can go for a larger diamond, making the solitaire all the more dramatic.
Design tip: A 1-2 ct lab-grown round or oval cut, set in a slim 14K or 18K band, allows for elegance and ethical impact in one.

Trend 2 – Oval & Cushion Cuts Taking the Lead

Round brilliant will always be beloved, but in 2025 we’re seeing a surge in oval and cushion-cut diamonds, especially among lab-grown pieces. Why? Because these shapes offer more visible surface area (spread) per carat, meaning a bigger “look” for the budget. Add that to the lab-grown value advantage and you have a trend that resonates.
Where once oval/cushion might have been niche, they’re now mainstream; and many couples are pairing them with halo or side-stone settings for extra sparkle.

Trend 3 – Yellow Gold and Rose Gold Make a Comeback

Platinum has dominated engagement rings for decades, but the pendulum is swinging back. In 2025, yellow gold and rose gold bands are experiencing renewed popularity — especially when paired with lab-grown diamonds. The warmth of the gold complements the brilliance of the white diamond and gives a vintage-modern hybrid appeal.
For a jewellery brand: offer lab-grown diamond rings in 14K or 18K yellow gold, or rose gold, and highlight that design as “heritage yet forward-looking”.

Trend 4 – Why Couples Are Choosing Lab-Grown Diamonds

Before we get into more design trends, it’s worth stopping for a moment to address why lab-grown diamonds are the go-to choice for these fashionable rings.

You're getting essentially the same stone (in terms of sparkle and durability) but at a better cost.
That allows you to increase size or improve cut/clarity without over-budgeting.
The ethical/sustainable story appeals strongly to modern brides and grooms.
The technical quality of lab-grown diamonds is now fully mission-ready for premium jewellery.
When you combine trend-leading design + conscious sourcing + value, lab-grown diamonds win for 2025 engagement rings.

Trend 5 – Mixed-Metal with Diamond Accents

Another rising trend: mixing metals (e.g., a yellow gold band with white gold prongs, or a rose gold band with a white gold halo) combined with a lab-grown diamond centre-stone. This aesthetic gives subtle contrast, a layered sparkle effect and the chance to customise — especially appealing to couples who care about individuality.
Your jewellery brand can highlight customisation services: choose your center lab-grown diamond, pick band metal(s), mix in side-stones or pavé, and deliver a bespoke feel at a competitive price thanks to lab-grown savings.

Trend 6 – Three-Stone & Hidden Halo Designs for Extra Drama

For buyers who want a little extra “wow,” three-stone rings or hidden halo settings are trending. A centre lab-grown diamond flanked by two smaller stones (either diamonds or coloured gems) or a hidden halo under the centre stone gives extra brilliance and visual complexity. Because lab-grown diamonds cost less per carat than mined ones, these more elaborate designs become more financially accessible.
Design tip: Offer a lab-grown 2 ct centre cushion cut with two 0.5 ct side stones, set in rose gold — powerful, dramatic, but still value-smart.

Trend 7 – Personalised Engraving & Ethical Storytelling

Finally, the 2025 trend isn’t just about how the ring looks — it’s about what the ring says. Couples are demanding personalisation: special dates, coordinates, hidden messages inside bands; and they’re demanding ethical transparency: where was the diamond made, what is the brand’s chemistry, what is the sustainability footprint.
When your brand uses lab-grown diamonds, you have a story to tell: “Our diamonds were grown in a controlled, ethical environment, certified by [lab], no mining, less impact, same brilliance.” Combine that with personalised engraving (and perhaps a certificate of origin or carbon-footprint statement) and you’re delivering a ring that resonates emotionally and visually.

How to Choose the Perfect Engagement Ring (with Lab-Grown Diamonds)

Step 1: Define your budget
Because lab-grown diamonds give more value per rupee, you may choose to upgrade size, choose a better cut or use a more elaborate setting.

Step 2: Choose the cut first
Cut influences sparkle more than carat size or colour. Choose a shape that fits your partner’s style (round, oval, cushion) and one that makes the most of the carat you’re investing.

Step 3: Decide the metal & setting
Do you want a minimalist band (solitaire) or a halo/side-stone design? Do you prefer yellow gold/rose gold for warmth or white gold/platinum for a cooler look? The trend is shifting toward yellow/rose in 2025.

Step 4: Confirm certification & origin
Ensure your lab-grown diamond is certified by a trusted grading lab, and that the origin/production method is disclosed. The same buyer caution applies here as with natural diamonds.

Step 5: Personalise the ring
Including engraving, mixed metals, hidden halo, custom side stones or special packaging/story card. This elevates the piece from jewellery to heirloom.

Step 6: Choose a brand with support
Look for after-sales service, resizing policy, upgrade/trade-in options. These matter when you want your engagement ring to serve long-term.

Why Your Jewellery Brand is the Ideal Partner for 2025 Trendsetters

As a brand specialising in lab-grown diamond jewellery, here’s how you can highlight your appeal in the 2025 market:

Trend-forward design: Offer the trending shapes (oval, cushion), popular metals (yellow/rose), and flexible settings (solitaire, halo, three-stone).
Value + transparency: Show how lab-grown allows greater carat size or better quality for the same budget. Explain the value proposition clearly.
Ethical-luxury story: Communicate the production story of your lab-grown diamonds, the certifications, the low-impact manufacturing.
Personalisation: Custom engravings, mixed metals, bespoke boxes, certificate of origin — all elevate the purchase.
Service guarantee: Offer resizing, cleaning, upgrade/trade-in programmes to build trust and long-term relationship.
Content-rich marketing: Blog posts (like this one), social media showing “2025 ring trend highlights”, customer stories, influencer features — all help build your authority in the niche.
Your brand becomes not just a vendor of rings, but a partner in helping modern couples choose a meaningful, stylish, future-ready engagement ring.

From minimalist solitaires and oval/cushion cuts to yellow/rose gold returns, mixed-metal craftsmanship and personalised touches — the modern engagement ring is a statement of style and values.
For your brand: lead with transparency, lead with design, and lead with value. Show your customers how a lab-grown diamond ring in 2025 is not a compromise—it’s a conscious upgrade.
Here’s to many modern love stories — and many sparkly, meaningful rings that reflect them.
