What an engagement ring really costs in Australia

By Rohan Allen, co-founder · Updated 24 October 2026 · Every figure sourced or from our own books

Australians spent an average of $6,842 on an engagement ring in 2026, up 14.5% in a year. Custom rings in the quality bracket most couples want sit between $8,000 and $20,000. Nobody in this industry will tell you where that money actually goes — so below is the complete, line-by-line cost of two of our rings, including our margin.

What Australians actually spend

The 2026 Easy Weddings industry survey puts the average Australian engagement ring at $6,842, up 14.5% on the previous year, with an average centre stone of 1.7 carats. Against roughly 121,000 marriages a year (ABS), that's about $800 million spent on engagement rings annually — before wedding bands.

Published surveys disagree more than you'd expect — figures range from about $5,400 to $9,000 depending on who was asked. We reconcile every published Australian number on our annually updated engagement ring cost statistics page.

That average blends everything from chain-store solitaires to one-off pieces. For a made-to-order ring with a certified centre stone from an independent studio — what we make — realistic budgets look like this:

Cost build: a natural 1.00 ct solitaire — $12,750

This is our four-claw solitaire (The Hawthorn) in 18ct yellow gold with a 1.00 ct G-colour VS1 round brilliant, GIA certified. Here is everything you're paying for:

The stone is roughly half the ring. That's normal at this level — anyone quoting you a natural 1 ct ring dramatically cheaper is saving the money on the stone's cut quality or the certificate, not on magic. For how the rest of the industry prices — keystone markups and all — see how much jewellers really mark up rings.

Cost build: a lab-grown 2.0 ct oval — $8,250

Same honesty on a lab-grown ring — a 2.0 ct G VS1 oval (IGI certified) in 18ct white gold with a hidden halo and pavé band:

The five choices that move the price

• Natural vs lab-grown. The single biggest lever. A 1 ct G VS1 natural round retails around $8,000 in Australia right now; the equivalent lab-grown stone is around $1,400. Same sparkle, different rarity and resale story — our diamond guide covers it without the sales pitch.
• Carat. Prices step up sharply at the "magic weights" — 0.50, 0.75, 1.00, 1.50, 2.00 ct. A 0.90 ct stone can cost 15–20% less than a 1.00 ct and look identical on a hand. We'll always show you the stone just under the magic weight.
• Cut, colour, clarity. Cut is the one worth paying for — it does the sparkling. G–H colour and VS2–SI1 clarity (eye-clean) are the sweet spots where the stone looks perfect and the price doesn't include grades you can't see.
• Metal. Gold is about $183 a gram fine right now, so a typical 5–6 g 18ct mount carries $700–$820 of metal before any labour. Platinum runs a little more. Rose, yellow and white gold cost the same as each other.
• Setting complexity. A halo adds melee stones and hours of setting work; pavé adds more. Budget roughly $400–$900 over a plain solitaire depending on coverage.

Why diamonds cost less than they did three years ago

Two things happened. Natural polished prices have fallen every year since 2022 — a 1 ct natural stone trades at roughly half its end-2021 level on the RapNet index. And lab-grown wholesale prices fell 26% in 2025 alone, with India's lab-grown exports averaging about US$60 a carat against US$760 for natural.

The practical upshot for you: a natural 1 ct ring that cost over $20,000 three years ago can genuinely be built for under $15,000 today, and it isn't a discount trick. It also means we buy your stone to order, on the day you commit — we never hold old stock bought at old prices, and your quote is priced at the day's market and held for 14 days.

Deposits and how you pay

Some studios take a 50% non-refundable deposit before anything is made. We think that's a lot to ask of someone who found you on the internet, so our structure is staged:

• $300 design fee to begin — credited in full against your ring.
• 50% when you approve the exact stone and the final render — this is the point your stone is bought, at that day's price.
• Balance only after you've seen the atelier's quality-control photos of your finished ring, before it ships.

How to compare two jewellers' quotes

Quotes at this level are hard to compare because most of them hide the structure. Seven questions that make any quote comparable — expanded into a printable 10-question checklist here:

1. Is the stone certified, and by whom? GIA or IGI, with the report number in the quote. No report, no comparison.
2. What are the exact 4Cs — including cut grade? "1 ct diamond" tells you almost nothing about price.
3. What's the mount's metal and weight? A 3.5 g shank and a 5.5 g shank look similar in a render and wear very differently over thirty years.
4. Is the price itemised? If a jeweller won't split stone from setting, they're keeping room to move the parts you can't see.
5. What's the lead time, in writing? And what happens if they miss it?
6. What exactly does the warranty cover? Most "lifetime warranties" exclude claw wear and stone loss — the two failures that actually happen. Here's ours, with the spec it rests on.
7. What does a resize cost in year three? Free-resize windows of 4–8 weeks are common and quietly useless; fingers change over years, not weeks.

Bring any competing quote to a consultation and we'll go through it line by line with you — including the lines where the other quote is better. It happens, and we'll say so.
