How many months' salary should I spend on an engagement ring?

Zero.

The whole premise is a marketing trick that stuck. De Beers ran a campaign in the 1930s - the Depression, of all times - and somehow “two months’ salary” became etched in the cultural brain. The number crept up over the decades. It was one month, then two, now three months gets thrown around on some wedding sites. None of it has anything to do with what a ring actually costs to make, or what you can afford.

What I see at the bench is a spectrum. Some clients spend $2,500 on a simple 14k solitaire with a lab-grown center and are thrilled. Others spend $45,000 on a custom platinum piece with a GIA-graded natural diamond and don’t blink. The gap is enormous, and it’s never about how many paychecks they gave up. It’s about what the stone calls for and what the relationship can handle without starting in a hole.

Last March, a client named Leo walked in. He had a spreadsheet. He’d calculated exactly 1.7 months of his take-home, arrived at $7,200, and wanted me to find a natural diamond near 0.80 carats that would hit that number. The problem was his partner hates small stones - she’d been pinning 1.5-carat oval rings on a secret Pinterest board for a year. We talked for twenty minutes. Leo canceled the spreadsheet, bumped his budget to $9,000, and we built a ring with a 1.48 carat lab-grown oval, E/VS1, in a simple 18k yellow gold cathedral setting. The snag was he’d internalized a rule that had nothing to do with the person he was marrying. That happens more often than you’d think.

If you need a number, here’s one from the bench: the most common engagement ring budget I see from couples who talk openly is between $6,000 and $11,000 for natural, and $3,500 to $7,000 for lab-grown. Those numbers are just the observation of one jeweler in a small studio. They are not a rule.

Hard advice? Do not finance a ring with a credit card you can’t pay off in 90 days. A marriage has enough financial conversations ahead without a diamond-debt starter kit. Spend whatever leaves your emergency fund intact and feels uncomfortable but not panicked. You can always upgrade the center stone on an anniversary.

I’d rather see a simple solitaire with a good stone and a rent check that still clears.
