Is $1,000 too cheap?
No. A thousand dollars buys a real gold ring with a real diamond in it, cut properly, set properly, and made to be worn every day. It is a small diamond. That is the only thing the budget decides.What makes a ring look cheap is almost never the price. It is a dull stone that was cut to hold weight instead of to return light, a band so thin it goes oval inside a year, and claws that were bent over the girdle rather than seated into it. All three of those are choices, and you can avoid all three at $1,000 by buying a smaller stone. The trap at every budget is spending on carat weight and letting the rest slide.
Well-cut, eye-clean diamonds, lab-grown drawn to one scale
Two things fall out of that ladder. The first is that spend and size come apart quickly: ten times the money is roughly twice the width on the finger, because carat weight is volume and what you see is a disc. The second is that the interesting decisions happen below $5,000. Above it you are mostly buying more of the same thing.Each rung carries two weights because origin moves the size more than anything else on this page. A natural diamond of the same cut, colour and clarity comes in at a little over a third of the lab-grown weight for the same money. The sizes quoted in the rest of this guide are the lab-grown ones unless they say otherwise.$1,000

What $1,000 buys
A lab-grown round or oval somewhere between a third and half a carat, roughly 4.3 to 5.2 mm across, in a four or six claw solitaire in 9ct or 14ct gold. Half a carat is not a token stone. It was the standard engagement diamond for most of the twentieth century and it still reads clearly as a diamond ring from conversational distance. The same money in a natural stone at the same grades buys closer to a fifth of a carat, about 3.8 mm across.At this budget the whole ticket is the stone and the metal, so the things to insist on are the ones that cost nothing extra: an excellent or ideal cut grade, a stone that is clean to your eye at arm's length, and a band no thinner than about 1.6 mm so it survives being worn. Skip the halo. A ring of tiny accent stones around a small centre adds setting cost, adds points of failure, and is the most common way a modest budget ends up looking busy rather than bigger.What you cannot have for $1,000 is platinum, a large stone, or bespoke work. Platinum costs more in raw metal and considerably more in bench time. If you want the white look, white gold at this budget is the sensible answer, replated every few years.
If the number is the problemA smaller stone now with a setting built to take a bigger one later is a real strategy, not a consolation. Upgrading the centre stone into an existing head is straightforward work. Rebuilding a ring around a stone it was never designed for is not.
What $2,000 buys
Between 0.7 and 0.9 carat in lab-grown, or around a third of a carat natural. The lab-grown range is the point where a stone stops looking deliberate about its size. A 0.9 ct round is 6.2 mm across against 6.5 mm for a full carat, a difference nobody has ever noticed on a hand. Paying for the round number is one of the easiest ways to waste money in this market, and a 0.9 can cost noticeably less than a 1.00 of identical quality.The second thousand also buys options the first one could not. 18ct gold instead of 9ct, so the colour is warmer and the metal holds a polish better. A slim pavé band, if that is the look. Or an elongated shape: a 0.8 ct oval or pear covers more finger than a 0.8 ct round, which is size you get for free by choosing well rather than by spending more. Our shape guide goes through which cuts spread and which hold their weight in depth.
What a $5,000 ring looks like
A lab-grown centre stone of 1.5 to 2 carats, 7.4 to 8.2 mm across, or a natural one of about 0.7 of a carat and 5.8 mm, in a setting that was chosen rather than settled for. This is the budget where the ring in your head and the ring you can buy tend to converge. It is large enough that people comment on it, and it is the range most Australians we speak to end up in.Platinum is comfortably affordable here, and worth it if you want white metal that stays white without replating. So is a hidden halo, a ring of small stones set under the centre where you see it only from the side, which lifts the apparent size without the cluttered look of a visible halo. So is a tapered or twisted band, or a fancy shape like an emerald or radiant cut where clarity has to be better because the facets do not hide inclusions.The honest advice at $5,000 is to stop climbing before you spend it all on carat weight. A 1.6 ct with an ideal cut, in platinum, on a band that suits the hand, outperforms a 2.1 ct with a good-not-excellent cut in 9ct gold every time, in person and in photographs.
At $7,000 and $10,000
Seven thousand dollars buys roughly 2 to 2.5 carats in lab-grown, or around 0.9 of a carat natural, so a lab-grown stone 8.2 to 8.8 mm wide, with the cut, colour and clarity all held at the top of the range rather than traded against each other. If you want a specific number for a $7,000 ring, two and a bit carats is the honest answer, though shape moves it: an emerald or oval of the same weight buys more visible length, a cushion or asscher slightly less.A $10,000 ring is 2.5 to 3.5 carats in lab-grown, about 1.2 carats natural, or a smaller stone in a setting that took real bench time. Three carats is unmistakable. It sits about 9.4 mm across, covers most of the width of an average finger, and is the point at which the stone becomes the thing people see first. The alternative use of the same money, which we suggest more often than people expect, is a 2 ct centre with a genuinely bespoke setting: a band designed around her hand, hand-cut pavé, an engraved gallery. Carat weight is the easiest thing to buy and the least personal.Above $10,000 the guide that covers the upper end is how much to spend on an engagement ring, which runs the same exercise up to $30,000.
If you earn $100,000
Most people on $100,000 a year land somewhere between $3,000 and $8,000. That is an observation about what our customers do, not a recommendation, and there is no rule underneath it. The salary rule is advertising copy. De Beers put one month's salary in front of buyers in the 1930s and raised it to two in the 1980s, and three months turned up later still. Each version was written to sell more diamonds, and all of them have been repeated often enough to sound like etiquette.The same answer applies to the question of how much a man should spend, which is asked far more often than the reverse and has exactly the same answer: whatever you can pay for without it costing you something else that matters. Nobody is checking. The useful test is not a multiple of income at all, it is three questions about your actual finances. Is the money already saved, rather than going on a card you will carry? Is it money that is not earmarked for a deposit you are actively saving for? And could you spend it and still handle a surprise next month?If all three are yes, the number is fine, whether it is $1,500 or $15,000. If any is no, spend less. A ring bought on a personal loan starts a marriage with a repayment schedule attached to it, and no stone is worth that.
Who pays for it
Traditionally the person proposing pays, alone, and keeps the cost to themselves. That convention is still the default in Australia and it is perfectly good if it suits you.It is also no longer the only respectable option. Plenty of the couples we work with choose the ring together and split it, particularly when they are already saving for a wedding or a house out of the same pool of money. Some put a family stone into a new setting and pay only for the making. Some have one partner buy the engagement ring and the other buy both wedding bands. None of these arrangements make the proposal less of a surprise if you want one; you can agree on a budget and a shape months ahead and still say nothing about when.The only version that reliably goes wrong is one person quietly spending money the other would not have agreed to. If you are already sharing finances, the ring is a joint decision whether or not it is a joint purchase.
Is a cheap diamond a real diamond?
This is usually asked about a specific retailer. Costco is the common one, and the answer there is yes: the diamonds are real, the engagement rings generally come with an independent grading report, and describing a stone as a diamond when it is not is illegal under Australian consumer law. A low price is not evidence of a fake stone. It is usually evidence of thin margins, plain settings, and no showroom on Collins Street.Price is not the test. The grading report is. Ask for an independent one from GIA or IGI, check that the report number is laser-inscribed on the girdle of the stone so the paper and the diamond are actually a pair, and read what it says at the top: a lab-grown diamond is identified as lab-grown on its report, because it is a diamond and gets graded like one. Our guide to reading a grading report covers what the grades mean and which labs are strict.The things worth being wary of at low prices are more specific than “is it real”. In-house or unnamed-lab grading, which tends to run two or three grades softer than GIA for the same stone. Listings that say “diamond accents” or give a total carat weight without a centre stone weight, which usually means many tiny stones and no real diamond. Moissanite or cubic zirconia described in language that never quite says diamond. And any seller who will not tell you the cut grade, which is the number that decides whether the ring sparkles.
One line to rememberA real diamond with a report you can verify is available at $1,000. A stone with no report is a bad buy at any price, including $10,000.
