The Ring Is No Longer the Whole Sale

The Knot's 2026 data show lab-grown stones now anchor 61 percent of U.S. engagement rings, and the more durable opportunity sits in the months of buying that follow the proposal.

A ring worn on the hand draws a closer look, shown in a circular inset over a red-carpet portrait.

The Knot's 2026 Real Weddings study, drawn from 10,474 American couples married in 2025, found that 61 percent of engagement rings carried a lab-grown center stone, a share that has grown 239 percent since 2020. Average spend on the ring itself was $4,600, with an average center-stone weight of 1.9 carats. Those three numbers describe a category that has not shrunk. It has reorganized around price.

The reorganization is stark once the averages are split by material. A natural-stone ring averaged $7,000 for a 1.6 carat center stone. A lab-grown ring averaged $4,300 for a 2.0 carat stone: larger and cheaper at once. Bank of America Global Research puts lab-grown diamonds at roughly 15 percent of the global diamond industry, up from under 1 percent in 2016, with the United States the largest buyer and bridal driving most of that volume. Forty percent of the couples in The Knot's study said a lab-grown stone was specifically important to them, not a fallback. The Gemological Institute of America is clear that lab-grown and natural diamonds share the same chemical composition, crystal structure, and optical properties; the difference is origin, and origin used to carry a premium of roughly 60 percent for a smaller stone. That premium is what buyers are now declining to pay by default.

Three lanes, one set of house rules

Taste has not swung toward novelty even as the pricing has moved. Clear stones still account for 83 percent of center stones and solitaires for 38 percent of settings. Round holds a narrow lead over oval, 26 percent against 25 percent, with emerald, princess, pear, and marquise splitting most of the remainder at roughly 8 percent each. The shift shows up in the details instead: yellow gold has risen 140 percent over five years to reach 39 percent of metal choices, and moissanite and sapphire have become the two leading non-diamond center stones for couples choosing a third lane entirely, past both natural and lab-grown. Couples rank cut and shape as their first decision, setting style second, metal third, and 88 percent made a custom edit or built a piece from a base design rather than buying it unmodified. That is a request for authorship, not for a fully bespoke commission on every order.

The purchase itself has stopped being a solo act. Seventy-nine percent of recipients in The Knot's study took part in choosing their own ring, and one in four couples shopped together in a store before any proposal happened. Fifty-seven percent of shoppers began research more than six months out, yet 77 percent completed selection and purchase within four months, visiting two retailers on average and handling roughly ten rings in person before deciding. Sixty-four percent still bought in a physical store. The surprise reveal survives. The unilateral decision behind it does not.

“My read: the lab-grown share is not a fad correcting itself, it is a repricing that already happened. Once a couple can put a 2.0 carat stone on the hand for $4,300 instead of $7,000 for 1.6 carats, paying purely for rarity requires a specific, stated reason: a family stone, a particular provenance, a story worth the premium. I expect natural diamonds to hold the top of the market by leaning harder into documentation and provenance through labs like GIA, not by competing on size against a lab-grown stone with identical optical properties.”

The ring is the opening appointment

The engagement ring sits inside a wedding that now averages $34,200, with wedding bands adding another $3,000 and additional jewelry averaging $390 more. Those figures describe a couple who stays in the market for months after the proposal: sizing bands, choosing ceremony pieces, eventually shopping for anniversary jewelry. The households doing this buying look different than they did a generation ago. The U.S. Census Bureau puts the median age at first marriage in 2025 at 30.8 for men and 28.4 for women, up from 23.5 and 21.1 in 1975, and married-couple households have fallen to 47 percent of all U.S. households, down from 66 percent five decades earlier. Marriage is later and reaching fewer households overall, even as the CDC's most recent full-year figure still counted just over 2 million marriages.

None of that argues for treating bridal as a shrinking category. It argues for treating each ring sale as the opening of a longer file: stone identity, metal, size, and a wedding date collected at purchase, followed by a band fitting weeks later and a styling conversation months before the ceremony. The brands still selling one ring and calling the relationship finished are leaving the steadier revenue, the bands, the resizing, the anniversary piece, sitting on the table for whoever follows up first.
