If you’ve felt whiplash on diamonds the last few years, you’re not imagining it. The two categories are moving in opposite directions, and both trends are worth reading carefully.
Start with lab-grown. Prices have fallen dramatically as production scaled — a one-carat lab-grown that sold for several thousand dollars a few years ago now often retails around a thousand or less. That’s great for accessible price points, but it’s reset margins and made “hold it and it’ll appreciate” a non-starter. Lab-grown is a fashion and value play now, not a store of value.
Meanwhile, natural diamonds have quietly steadied. After years of losing ground in engagement rings, natural’s share of bridal ticked back up in 2025 — a majority of couples again chose a mined stone for the milestone purchase. The commoditization of lab-grown seems to be reinforcing the prestige of natural for once-in-a-lifetime buys.
For most retailers, the takeaway isn’t to pick a side — it’s to carry both and be straight with customers about the trade-off. Lab-grown gets you size and sparkle for the budget. Natural carries rarity, resale perception, and the story that still matters for weddings and anniversaries.
Two practical notes: quote lab-grown and natural as clearly different products (never let a customer feel misled), and watch the spread — because lab-grown pricing is still settling, the stone you quote today may cost less next quarter. Source close to the sale rather than stocking deep.
