The traditional diamond industry just got a serious wake-up call. According to the latest data from The Knot, 2025 marked the official “takeover” of lab-grown diamonds in the engagement ring market. Couples are ditching the natural pipeline in favor of LGD  stones that offer more sparkle for fewer dollars.

Here is the breakdown of how the engagement ring landscape shifted over the last year.

The Lab-Grown Revolution

The numbers don’t lie: synthetic stones are no longer a “budget alternative”—they are the primary choice.

• Market Dominance: 61% of couples chose a lab-grown center stone in 2025.
• The Growth Factor: That’s a staggering 239% increase since 2020.
• The “Why”: It’s a mix of economic pragmatism and evolving values. In fact, 40% of buyers specifically sought out lab-grown stones for ethical or personal reasons.

 Spending vs. Size: The Great Trade-Off

While couples are spending less on average, they are walking away with much bigger rocks.

Bottom Line: The average total spend on rings dropped from $5,200 in 2024 to $4,600 in 2025, yet the average stone size grew from 1.7 to 1.9 carats. Essentially, couples are getting “more for less.”

Style Trends: Yellow Gold is Back

It’s not just about the stone; the “look” of the ring is evolving too.

• Metal Magic: Yellow gold is the undisputed champion at 39% demand (a 140% jump over five years), while white gold continues to lose its luster.
• The Silhouette: Solitaire settings remain the top pick (38%), emphasizing the “big stone” aesthetic.
• Shape Shifters: While Round is still the #1 shape overall (26%), Ovals are hot on its heels at 25%. Emerald, princess, pear, and marquise shapes follow behind at 8% each.
• The Personal Touch: 90% of couples opted for custom designs or edits—the “cookie-cutter” ring is officially out.

The Shopping Experience: High-Tech Stones, Old-School Service

Despite the rise of lab-grown tech, couples still want a “main street” experience.

• In-Person Preference: Over 50% of couples say shopping in person is a must.
• The Hunt: On average, proposers visit two retailers and look at 10 different rings before pulling the trigger.

• Final Click vs. Handshake: 64% of purchases were made in-store, with only one-third of couples buying online.
