Jewelry Brand Unit Economics: The Lines a CFO Checks First
Jewelry unit economics start with landed cost, not the supplier invoice, and end with contribution margin, not gross margin. Public comps post 39.5% to 57.5% gross margin but under 6% operating margin. A 70% gross margin compresses to a 15% to 30% contribution margin after returns and fulfillment, and high AOV is what lets jewelry carry a $120 to $180 CAC.
Key Takeaways
- Gross margin is the line that tells you the least. Public jewelry comps span 39.5% to 57.5% gross margin (Signet, Movado, Brilliant Earth, SEC 10-Ks), yet operating margin collapses to a -1.2% to +5.8% band. The category does not set your margin. Your business model does.
- Build landed cost before you trust any margin number. True COGS is metal plus stone plus labor plus inbound freight plus duty plus fees, not the supplier invoice. Keystone (2x) on the invoice alone overstates your real gross margin.
- A 65% to 75% gross margin compresses to a 15% to 30% contribution margin once shipping, processing, packaging, and a 15% to 20% return rate hit. Contribution margin, not gross margin, is the line that sizes your ad budget.
- Jewelry has the highest CAC and lowest conversion in ecommerce. Fine-jewelry DTC CAC runs $120 to $180+ on 0.8% to 1.5% conversion. High AOV ($500+, bridal $2,000+) is the only reason the math works. Target CAC payback of 1 to 3 months on contribution margin.
- Inventory is the hidden cash trap. Stock-heavy jewelers hold 172 to 186 days of inventory; made-to-order DTC holds 75. That spread never shows up on your margin line, but it decides how much cash you can actually deploy.
Jewelry founders fall in love with gross margin. Keystone pricing (2x markup) implies a 50% gross margin, DTC fine jewelry routinely quotes 60% to 75%, and the topline number looks gorgeous on a pitch deck. But unit economics is what a fractional CFO actually underwrites, and in jewelry the gross-margin line is the least informative number in the model. This guide takes a jewelry operator from the headline margin down through the four lines that decide whether the brand scales: landed cost, contribution margin, CAC payback, and inventory turns. It teaches the model; our jewelry financial benchmark report provides the benchmark band to check your numbers against.
For an adjacent category, compare our beauty brand unit economics, and if you want this modeled on your own numbers, that is the day job of a fractional CFO.
Gross margin is the prettiest lie in your jewelry P&L
The first reflex of almost every jewelry founder is to price at keystone, see a 50% gross margin, and feel good. The second reflex is to read a blog that quotes "60% to 75% DTC fine-jewelry margins" and assume that is the number to model. Both reflexes anchor on the line that, in this category, tells a CFO the least.
The three public jewelry comps prove it. Pull the FY2026 10-Ks and gross margin spans a 40% to 58% range, set entirely by business model, not by the fact that everyone sells jewelry. Signet, the mall and bridal retailer, posts 39.5% gross margin on $6.81B of revenue. Brilliant Earth, the asset-light made-to-order DTC brand, posts 57.5% on $437.5M. Movado, accessible-luxury watches and jewelry, lands in between at 54.2%. An 18-point gross-margin spread inside one category should be the first sign that a generic "70% jewelry margin" is a number no public jeweler actually earns.
Now watch what happens lower down the P&L. Operating margin collapses to a -1.2% to +5.8% band. Signet keeps 5.8% of revenue as operating income, Movado 4.4%, and Brilliant Earth runs an operating loss at -1.2% as acquisition cost climbed. Almost none of that gorgeous gross margin survives to the operating line. That gap, between a 40% to 58% gross margin and a sub-6% operating margin, is the entire unit-economics story.
When I talk to founders running a jewelry brand in the $3M to $20M range, the thing they keep saying is some version of "but my margins are great." They mean gross margin. Then we open the actual P&L and the operating line is barely positive, and the conversation finally moves to where it should have started: what is eating the spread.
| Company | Ticker | FY end | Revenue ($M) | Gross margin | Operating margin | Inventory ($M) | Turns | Days inv. |
|---|---|---|---|---|---|---|---|---|
| Signet Jewelers | SIG | 2026-01-31 | 6,813.6 | 39.5% | 5.8% | 1,937.3 | 2.13x | 172 |
| Movado Group | MOV | 2026-01-31 | 671.3 | 54.2% | 4.4% | 156.7 | 1.96x | 186 |
| Brilliant Earth | BRLT | 2025-12-31 | 437.5 | 57.5% | -1.2% | 38.3 | 4.86x | 75 |
True COGS: build landed cost before you trust any margin number
You cannot read a gross-margin line you have miscalculated. The most common COGS error in jewelry is treating the supplier invoice as the cost of goods. It is not. The supplier invoice is one component of landed cost, which is the all-in cost to get a finished piece into your warehouse, ready to sell.
A real jewelry landed cost is metal plus stone plus labor plus inbound freight plus customs duty plus fees (insurance, brokerage, handling). Each line moves with things outside your control. Metal floats with the spot price and the finished weight of the piece. Stone cost depends on the center and setting stones. Duty depends on the import classification and origin. Leave any of these out and your "50% keystone margin" is fiction.
Here is an illustrative landed-cost build for a single fine-jewelry SKU. The dollars are an example; the lesson is the line items.
| Cost component | Per-unit cost | Notes |
|---|---|---|
| Metal | $80 | Weighted by purity and finished weight |
| Stone | $120 | Diamond / gemstone / setting stone |
| Labor | $40 | Casting, setting, polishing, QC |
| Freight (inbound) | $10 | Supplier to warehouse |
| Duty | $15 | Customs / import duty |
| Fees | $5 | Insurance, brokerage, handling |
| = Landed cost | $270 | True per-unit COGS |
| Keystone retail (2x) | $540 | 50% gross margin before channel fees |
Notice that the $30 of freight, duty, and fees on this unit is roughly 11% of the $270 landed cost. A founder who priced off the $240 of metal, stone, and labor alone would think they were earning a 56% margin at a $540 retail. They are not. The supplier invoice is not your COGS, and the so-called 2:1:1 rule (sell at roughly twice your cost, with material and labor each a slice of that cost) only protects you if "cost" means landed cost. When we've struggled to explain why a brand with "great margins" keeps running out of cash, the answer is almost always hiding in the freight, duty, and fees nobody loaded into COGS.

Contribution margin: the line that decides how much you can spend
Gross margin tells you what is left after COGS. Contribution margin tells you what is left after COGS and the variable costs of actually selling and shipping the order. It is the line a CFO sizes ad spend against, and in jewelry it is dramatically lower than the gross margin founders quote.
Start a representative order at a 70% gross margin and subtract the variable costs jewelry founders routinely forget. Shipping and fulfillment take a slice. Payment processing takes about 3%. Packaging, which for jewelry is not cheap because the box is part of the product, takes more. Then the big one: a 15% to 20% return rate, which means a returns reserve that eats double-digit points of revenue. Add transactional discounting and the 70% gross margin compresses to a 15% to 30% contribution margin (CM2). That is the pool you fund growth from.
| Step | % of revenue | Cumulative margin |
|---|---|---|
| Gross margin (after COGS) | 70% | 70% |
| Less: shipping & fulfillment | -9% | 61% |
| Less: payment processing | -3% | 58% |
| Less: packaging | -4% | 54% |
| Less: returns reserve (15-20%) | -18% | 36% |
| Less: transactional discounting | -14% | 22% |
| = Contribution margin (CM2) | 22% | 22% |
This is also where the benchmark report and this guide could look like they disagree, so it is worth being precise. The benchmark band quotes a 55% to 75% contribution margin for fine jewelry. That is CM1, after COGS only. The 15% to 30% number here is CM2, after COGS and variable selling costs. They are different lines, and the whole point of this section is that the line you spend against is CM2, not CM1. The pattern we see again and again is a founder budgeting ads against a 65% CM1 when the order is really throwing off a 22% CM2, then wondering why a 3x ROAS still loses money.
CAC, CAC payback, and LTV:CAC: jewelry's unforgiving acquisition math
By the industry benchmarks, jewelry carries among the highest customer acquisition cost (CAC) and the lowest conversion of any ecommerce category. Jewelry ecommerce CAC averages around $91, but fine and luxury DTC runs $120 to $180+, with premium positioning pushing past $250. The reason is structural: conversion sits at 0.8% to 1.5% and cart abandonment runs near 82%. You pay for a lot of traffic that leaves without buying.
So why does anyone build a jewelry brand? Because AOV is the structural offset. Fine-jewelry AOV easily exceeds $500, bridal runs $2,000+, and even one high-ticket order can recover a $150 CAC on the first purchase. That is the trade jewelry makes: a brutal CAC, carried by a high ticket. It is why jewelry posts the highest LTV:CAC in DTC, around 5.2:1, despite the lowest repeat rate, roughly 10% versus about 28% DTC-wide. You win on ticket size and lifetime value, not on frequency.
Two guardrails matter here. First, CAC payback should land in 1 to 3 months on contribution margin; past 6 months and you are funding growth out of cash reserves. Second, LTV:CAC of 3:1 on margin dollars is the survival line, and 4:1 to 5:1 is healthy. The trap is measuring LTV on revenue instead of margin: a $1,800 lifetime revenue against a $150 CAC looks like 12:1, but at a 22% contribution margin the real ratio is closer to 2.6:1, which is below the survival line.
| Metric | 2026 benchmark (DTC fine jewelry) | Basis |
|---|---|---|
| Gross margin | 55-75% | SEC comps 39.5-57.5%; web DTC 60-80% |
| Contribution margin (CM2) | 15-30% of net revenue | After fulfillment / processing / returns |
| AOV | $500+ (bridal $2,000+) | Demi-fine / fashion $40-85 |
| Paid CAC | $120-180 per new customer | $70-180 range across sources |
| CAC payback | 1-3 months on contribution margin | Cross-DTC guardrail applied to jewelry |
| LTV:CAC | 3:1 survival / 4-5:1 healthy | Luxury ~5.2:1 |
| Return rate | 16.9-20% overall (10-12% strong) | Fine jewelry runs lower than fashion |
| Inventory turns | 1-3x per year | SEC comps 1.96-4.86x |
The single most common unit-economics mismatch we see is a fine-jewelry brand running sub-$400 AOV with a fine-jewelry cost structure and a fine-jewelry CAC. That is fashion-jewelry economics bolted onto a fine-jewelry P&L, and it does not pay back. Either the AOV has to rise to carry the CAC, or the cost structure has to come down to fashion levels. You cannot straddle both.
Inventory turns: the cash trap that never hits your margin line
The last line is the one founders skip because it lives on the balance sheet, not the P&L: inventory. It never shows up in your margin, but it decides how much cash you can actually deploy. In jewelry, where each unit carries metal and stone value, this is where cash quietly drowns.
The public comps show the spread starkly. Movado holds about 186 days of inventory (1.96x annual turns). Signet holds about 172 days (2.13x). Made-to-order Brilliant Earth holds just 75 days (4.86x), because it does not build the piece until the customer orders it. That is a 2.5x difference in how long cash sits in product, driven entirely by inventory model, not by anything in the margin lines.
Gross margin is the input founders fixate on and the line that tells a CFO the least. The four numbers that actually decide whether a jewelry brand scales sit elsewhere: landed cost, contribution margin, CAC payback, and inventory days. Get those four right and the operating margin follows. Stare at gross margin alone and you will run out of cash with great-looking margins.
When I talk to founders sitting on 180+ days of inventory, the cash conversation is never about margin. It is about how many months of stock they have funded out of pocket while waiting for it to sell. A brand can post a textbook gross margin and still be insolvent because every spare dollar is locked in unsold rings. Inventory turns belong inside a jewelry unit-economics review even though they sit on the balance sheet, and a made-to-order or pre-order model is the most direct lever a founder has to free that cash.
Reading your own jewelry P&L: a CFO's guardrails
Put it together and you have a short checklist to run against your own numbers. None of these are pass/fail on their own; they are the flags that tell you which line to dig into.
Gross margin below 55% on a DTC channel usually means underpricing or undercounted landed cost. AOV below $400 paired with a fine-jewelry CAC is a model mismatch: you are running fashion economics on a fine-jewelry cost base. Contribution margin (CM2) below 10% means you are repeat-dependent in a category with a roughly 10% repeat rate, which is a fragile place to be. CAC payback past 6 months means you are funding growth out of cash, not out of the orders themselves. Inventory turns below 1x means over-assortment, with cash trapped in slow stock. And LTV:CAC below 3:1 on margin dollars (not revenue) signals a retention problem the high ticket is not covering.
The operator move is to stop benchmarking your jewelry brand against generic "DTC" numbers, which were built mostly on apparel and consumables with very different frequency and ticket. Build the unit-economics model jewelry-specifically, and use the public comps and the 2026 benchmark band as guardrails. For the full set of bands by revenue size, our jewelry financial benchmark report is the companion to this guide.
Sources and methodology
The jewelry-specific figures in this guide come from SEC EDGAR 10-K XBRL filings for the three live public jewelry comps, pulled for the jewelry financial benchmark report and reused here. Signet Jewelers (CIK 0000832988), FY2026 ended 2026-01-31: revenue $6,813.6M, COGS $4,119.0M, gross profit $2,694.6M, operating income $393.1M, ending inventory $1,937.3M, for a 39.5% gross margin, 5.77% operating margin, and 2.13x turns (172 days).
Brilliant Earth Group (CIK 0001866757), FY2025 ended 2025-12-31: revenue $437.5M, COGS $186.0M, gross profit $251.5M, operating income -$5.4M, inventory $38.3M, for a 57.5% gross margin, -1.23% operating margin, and 4.86x turns (75 days). Turns use the FY2024 ending inventory as the base because FY2025 ending inventory was not separately XBRL-tagged.
Movado Group (CIK 0000072573), FY2026 ended 2026-01-31: revenue $671.3M, COGS $307.7M, gross profit $363.6M, operating income $29.8M, ending inventory $156.7M, for a 54.2% gross margin, 4.44% operating margin, and 1.96x turns (186 days). Ratios throughout are gross margin = gross profit / revenue, operating margin = operating income / revenue, inventory turns = COGS / ending inventory, and days = 365 / turns. SIC 5944 (Retail-Jewelry Stores). Signet is the dominant pure-play public jeweler, since most historical peers were acquired or went private, which is a limitation worth stating.
The web benchmarks (contribution margin, CAC, CAC payback, LTV:CAC, AOV, return rate, conversion) are triangulated industry ranges from Foundry CRO's 2026 DTC luxury benchmarks, Branvas 2026, First Page Sage / Prospeo, ltvcacbook.com, and Yotpo, cross-checked against each other and against the SEC primary figures. They are secondary, industry-reported ranges, not audited figures, and we have labeled them as such throughout.
Two sourcing notes matter for how you use the numbers. The 1-to-3-month CAC payback benchmark is a cross-DTC guardrail (ltvcacbook.com, Prospeo) applied to jewelry, not a jewelry-audited figure; treat it as a target, not a measured category norm. And the contribution-margin numbers in this guide are CM2 (after COGS and variable selling costs), which is a different and lower line than the CM1 (after COGS only) band quoted in the benchmark report. Keeping those two straight is the core teaching point of the contribution-margin section.
Frequently asked questions
what is the average profit margin for a jewelry brand?
At the gross-margin line, public jewelers run 39.5% to 57.5%. But operating margin, the number that reaches the bottom line, sits at just -1.2% to +5.8%. The gorgeous gross margin you hear quoted does not survive marketing, fulfillment, and overhead. Most jewelry brands net low single digits if they net anything at all.
what gross margin should a jewelry brand have to be profitable?
For DTC fine jewelry, target a 55% to 75% gross margin after a full landed cost (not the supplier invoice). Below 55% on a direct channel, you are probably underpricing or undercounting COGS. But gross margin alone does not make you profitable. Your contribution margin and CAC payback decide that.
why is my jewelry brand's operating margin so thin when gross margin looks great?
Because the gap between gross and operating margin is where jewelry actually lives. Signet earns 39.5% gross but 5.8% operating; Brilliant Earth earns 57.5% gross but loses money at the operating line. Marketing (jewelry has the highest CAC in ecommerce), fulfillment, returns, and SG&A eat the spread. The fix is to size spend against contribution margin, not gross.
what are the common pitfalls in calculating cogs for a jewelry brand?
The biggest one is treating the supplier invoice as your COGS. True landed cost adds inbound freight, customs duty, insurance, brokerage, and handling on top of metal, stone, and labor. Skip those and a 2x keystone markup that looks like a 50% gross margin can really be 40% or less once the goods actually land in your warehouse.
what contribution margin should a jewelry brand target to scale profitably?
Aim for a 15% to 30% contribution margin (CM2) after COGS, shipping, payment processing, packaging, and a returns reserve. That is the pool you fund ads from. Under about 10%, you are dependent on repeat purchases that jewelry's low frequency may not deliver, so any CAC increase puts you underwater fast.
what's a normal customer acquisition cost for a fine jewelry brand in 2026?
Jewelry ecommerce averages around $91, but fine and luxury DTC runs $120 to $180+, and premium positioning can push past $250. Jewelry carries the highest CAC in ecommerce because conversion is low (0.8% to 1.5%) and cart abandonment runs near 82%. You can only afford it because AOV and LTV are high.
what is a good cac payback period for a jewelry brand?
One to three months on contribution margin is the target. Because fine-jewelry AOV is high, a brand can sometimes recover CAC on the first order. If your payback runs past six months, you are funding growth out of cash reserves and betting on a repeat rate that jewelry (roughly 10% repeat) often will not pay.
what ltv to cac ratio does a jewelry brand need to scale?
3:1 on margin dollars is the survival line; 4:1 to 5:1 is healthy. Jewelry actually posts the highest LTV:CAC in DTC (around 5.2:1) despite the lowest repeat rate, because high AOV and LTV ($1,500 to $2,500) carry the load. If you measure LTV on revenue instead of margin, you will flatter the ratio and over-spend.
