What is an average engagement ring markup?

20 years ago, when I first set foot on 47th Street, the standard jewelry store markup was around 300%. That was the rule of thumb for a mined diamond engagement ring sold at a suburban mall. Today? It's more fractured. You'll see everything from 100% to 400%, depending on where you buy, what you buy, and whether the store pays rent for that marble foyer.

The big chain stores-the ones with the lighting that makes every stone look two grades higher-still operate on a 2.5x to 4x multiple on the stone and the mounting. A ring that costs them $3,000 might hit the floor at $9,000, then get a "sale" to $8,100. Megan walked into my studio last spring with exactly that ring. She'd paid $12,000 the year before at a mall jeweler: 1.5 carat round brilliant, I color, SI2, strong blue fluorescence. The mounting was a halo set in 14k white with the thinnest pavé shank I'd seen in months-about 1.5mm at the bottom. She was already missing two melee. For $12,000, I could have built her a 1.8 carat old European cut, G/VS2, in an 18k gold solitaire with a 2.4mm band and money left over for a simple wedding band. That's not a brag. That's the cost of a lease at a high-traffic mall and a national advertising campaign.

Online retailers have squeezed the markup to something leaner. For a GIA-graded natural diamond, 18% to 35% over wholesale is common. Some DTC brands running on volume are at 15% because they sell sight unseen and hope you don't return it. But they still charge a premium on mountings-a cast 14k setting that costs them $120 wholesale might show up at $450. Markup just moves around; it doesn't vanish.

Custom work sits in a different place entirely. I'm not selling you a product in a velvet box; I'm selling my bench time, my stone sourcing, and 22 years of mistakes I won't repeat. I generally price custom at 1.8 to 2.5 times hard costs-the metal, the stone, the casting, the setting-plus a design fee that covers the hours I spend drawing, modifying CAD, and emailing you photos at 11 p.m. A $2,000 stone and a $600 mounting might become a $5,200 ring. That's a lower multiple than the mall, but the total can still sting because you're seeing the cost of skilled labor, not just materials. The difference is, you're paying for a ring that wasn't rushed through a subcontractor's bench. The prongs are tipped properly. The shank isn't hollow. The engraving isn't stamped.

Lab-grown diamonds are the wild card. Wholesale prices have dropped 80% in five years, and they're still falling. A retailer who bought a 1 carat CVD at $800 six months ago and sold it for $2,400 was working on a 3x markup. Today that same stone might wholesale for $350, but the store still has it on the shelf at $2,400. I've seen this happen. It makes the whole concept of "average" meaningless for lab-grown right now. If you're buying lab-grown, ask when they purchased the stone. If they won't tell you, assume the markup is higher than the stone's current replacement cost. I'll set lab-grown-they're real diamonds-but I won't pretend the pricing is stable.

The antique and estate market is another beast. Dealers often work on a 1.3x to 2x markup because the stones are unique and the provenance carries a premium that resists commoditization. A 1.2 carat old European cut, K/VS1, from a 1920s setting might cost a dealer $3,800 at auction and list at $7,200. That markup includes their expertise in identifying an untouched stone versus a recut, their time at the auction house, and the risk of buying a stone that sits in the case for 18 months. I don't begrudge that. I do begrudge a mall store selling a generic I1 round for $9,000.

Here's what I tell clients who want to know if they're overpaying: ask to see the stone under different light, off the showcase. Ask for the GIA report and look at the date-if the stone was graded three years ago, the markup might be based on an old, higher wholesale price. Ask for the mounting weight in grams; a 2.8 gram ring that was cast as a single piece is worth more than a 1.6 gram ring assembled from stamped parts. And if the salesperson can't answer those questions, the markup is paying for their lease, not their expertise. That's your answer.

Markup isn't theft. It's how a jeweler feeds their family. What makes it fair or foul is whether you're getting something in return: a stone chosen with care, a setting that will survive daily wear, and the knowledge that the person who built it knows your name. If the ring came off a rack and the salesperson's name was on a tag, you probably paid too much.
