The Two Months' Salary Myth, Debunked
This is part of our full guide to why custom doesn't cost more.
Where the rule actually came from
In the late 1930s, De Beers hired the ad agency N.W. Ayer to solve a business problem: diamond demand had collapsed through the Depression, and Americans in particular weren't strongly attached to diamond engagement rings.
The campaign that followed is one of the most successful in advertising history. It produced "A Diamond Is Forever" in 1947, it placed diamonds in films and on celebrities, and — crucially for our purposes — it introduced a spending benchmark. One month's salary. Later campaigns pushed it to two. In Japan, where De Beers ran a separate effort starting in the 1960s, the suggested figure was three.
Notice what's happening there. The number moves. A genuine tradition doesn't get revised upward by a marketing department, and it doesn't have a different value in different countries based on what the local market will bear.
The campaign worked spectacularly. Within a few decades the diamond engagement ring went from uncommon to near-universal in the US, and the salary rule went from ad copy to something people repeat as if their grandparents said it.
Why the rule refuses to die
Three reasons, and understanding them helps you let go of it.
It's a heuristic in a decision with no anchor. Most people buying an engagement ring have never bought jewelry at this level and have no reference for what things should cost. Any number feels better than no number. The salary rule fills that vacuum.
It scales, which makes it feel fair. "Two months' salary" sounds like it adjusts to your circumstances. It doesn't really — it ignores debt, savings, cost of living, and everything else about your actual finances. Two months' salary for someone with student loans in Miami and two months' salary for someone with no debt living rent-free are not the same act.
It's a proxy for effort. This is the emotional core of it. People don't repeat the rule because they think it's accurate. They repeat it because they want a way to show the ring mattered. That instinct is good. The metric is bad.
What the rule gets wrong
It measures the wrong thing. Spending is an input. Nobody wears an input. What she'll actually experience is the ring — the shape, the proportions, whether it suits her hand, whether it's built well. Those are design decisions, and the correlation between price and good design is much weaker than people assume.
It ignores your balance sheet completely. A rule based on income and blind to savings, debt, and obligations isn't a financial rule at all. Two months' gross salary can be trivially affordable or genuinely damaging depending on facts the rule never asks about.
It creates avoidable debt. The rule pushes people toward financing decisions they wouldn't otherwise make. We look at the actual math of that in should you finance an engagement ring.
It's an anchor a salesperson can use. If you walk in having decided your budget is a fixed fraction of your salary, you've handed over your number before the conversation started. Anchoring is the single most powerful pricing tool there is, and this rule pre-anchors you against yourself.
What people actually spend
Real spending is far more spread out than the rule implies, and the distribution is wide in both directions. Surveys consistently show a large gap between average and median — a small number of very expensive rings drag the average well above what most people actually pay. When you see an "average engagement ring cost" headline, you're usually looking at a mean skewed by outliers, not a typical purchase.
The more useful observation: there is no correlation between what someone spent and how happy they are with the ring. What predicts satisfaction is whether the ring suits the person wearing it.
Better ways to set the number
Start from your savings, not your salary. What can you pay for now, without financing, without touching your emergency fund? That's your ceiling. It's a boring rule and it's the right one.
Subtract the other costs coming. An engagement is usually followed by a wedding, and sometimes by a ring upgrade, a honeymoon, or a move. Budget the ring as one line in that sequence, not as an isolated event.
Ask what she'd actually want you to spend. Uncomfortable, and worth it. A surprising number of people would be genuinely upset to learn their partner went into debt for a ring, and would rather have a smaller stone and a down payment.
Decide what the ring needs to do. If she wants presence on the hand, prioritize spread and cut. If she wants something delicate and unusual, budget goes further. Design intent is a better budget driver than a percentage.

Frequently asked questions
Is the two months' salary rule gross or net income?
It was never specified, which tells you everything about how rigorous it is. The ad copy said "two months' salary" without defining pre- or post-tax, before or after obligations. A real financial guideline would define its own terms.
Did De Beers really invent this?
The campaign that popularized it was created for De Beers by N.W. Ayer, and the suggested multiple was raised over time and set differently in different markets. That's marketing, not tradition.
Is there any spending rule that's actually valid?
Only the general one that applies to any discretionary purchase: spend what you can pay for without borrowing and without draining your reserves. Everything more specific than that is someone else's number.
Will she be disappointed if I spend less than two months' salary?
She almost certainly doesn't know what two months of your salary is, and won't be doing that arithmetic. What people notice is whether the ring looks like it was chosen for them.
What if her friends or family bring up the rule?
Then you get to be the person who knows it was ad copy from the 1930s. That's a better story than the rule.
So where does this leave you?
The rule is a leftover. It solved a business problem for a diamond cartel in the middle of the last century and it's been floating around ever since because nobody replaced it with anything.
You don't need a replacement rule. You need two numbers: what you can comfortably pay for outright, and what the ring needs to look like to be right for her. Those two numbers do all the work the salary rule pretended to do, and they're both actually about your life.
What we'd rather you anchor to
We're designers, not a store, and the honest version of this is that we'd rather you anchor to a number you chose than a number an ad campaign chose.
Here's ours. What you pay us for is the design and the craftsmanship — typically $1,500 to $4,000 — and you still walk away with a real, certified diamond ring. If your stone is larger or rarer, or the design gets genuinely complex, it can go higher, and we'll explain exactly why before you commit to anything.
Compare that to the alternatives on the same ring. A traditional retail jeweler: around $12,000. That same finished ring bought wholesale: about $8,000. Prices came down once when lab-grown diamonds arrived. Designer-direct is the third era, and it's the one you're standing in.
Which means the salary rule doesn't just have bad math behind it — it has outdated math. It assumed a retail price structure that isn't the only option anymore.
How it works: we sit down in person or virtually and design the concept together in the meeting, with AI-assisted visuals so you can see it. Your CAD file comes about three days later. You approve it and pay the balance from a link we email you. Ring ready about two weeks after that.
Amana means "trust." Earn your trust, make your ring.
