How to choose an engagement ring you'll both love.

This is the part nobody really tells you.

Buying an engagement ring is one of the most emotionally weighted purchases you'll ever make. It's also one of the most opaque. Most "guides" online are written by jewellers selling you something specific, or content marketers who've never set a stone. This isn't that.

What follows is what we actually tell our clients — full sentences, no upsell. Read it end-to-end if you have an hour, or use the table of contents to jump to the bit you need right now. Either way you'll come out of it knowing how to make a confident call.

You'll also notice we don't push a single answer. There isn't one. The best engagement ring is the one your partner will look down at in a meeting, twenty years from now, and still smile. Everything below is in service of that.

Setting a budget — and the myth you can safely ignore.

The "two months' salary" rule is a 1930s De Beers ad line. It is not a rule. It is not a tradition. It is marketing copy that survived because it stuck. Ignore it.

Here's what's actually true in 2026:

How to actually set a number

Forget percentages of salary. The honest method is three short questions, in this order:

• What can you genuinely spend without flinching? Not what's on a credit limit — what comes out of savings, or out of cash flow over six months, without straining the wedding fund or the deposit on a house.
• What's important to your partner — size, brand, ethics, design? A 1.5ct lab-grown solitaire and a 0.7ct natural three-stone can land at the same price. The "right" trade-off is whichever one she'd choose herself.
• What does the wedding band stack look like? Most couples buy two rings later — a matching wedding band for her and a band for the partner. Budget for the whole picture, not just the engagement ring.

Hidden costs to factor in

• Insurance: $40 – $120 per year in Australia for a $5K – $10K ring. Worth it from day one.
• Resizing: Free with us for the first 60 days. After that, $80 – $150.
• Wedding band: $1,500 – $4,000 for a matching diamond-set band, less for plain.
• The proposal itself: If you're going for a big-gesture proposal — photographer, restaurant, holiday — that's a separate budget line.

If you'd like to spread the cost, we offer interest-free in-store financing as well as Afterpay and Zip. See financing options.

The 4Cs — in ninety seconds.

You'll hear about the "Four Cs" everywhere — Cut, Colour, Clarity, Carat. They're the international grading system every certified diamond is rated on. Here's the version that actually helps a buyer:

Cut — the only one that matters most

Cut is how well the diamond's facets are angled. It's the difference between a diamond that fires light back at you across a room and one that looks like glass under your finger. If you only optimise one C, optimise this one. Aim for Excellent or Ideal cut.

Colour — D to Z, but you don't need a D

Colour is graded D (colourless) to Z (yellow tint). The honest secret: most people can't tell the difference between D and G to the naked eye, and once the diamond is set in white gold, you can comfortably go to H. Yellow gold setting? You can go to J without anyone noticing. The savings are significant.

Clarity — flawless is overpriced

Clarity grades the tiny natural inclusions inside a diamond. Ranges from FL (flawless) down through VVS, VS, SI, I. The sweet spot for most engagement rings is VS2 or SI1 — inclusions that are invisible to the naked eye, but the price is meaningfully lower than VVS or FL.

Carat — weight, not size

A carat is a unit of weight (0.2 grams). Two diamonds at 1.0ct can look very different in size depending on cut. Three buyer hacks: shy carats save money (a 0.95ct looks identical to 1.0ct and costs ~10% less), shape changes apparent size (an oval or pear looks larger than a round at the same carat weight), and halos add visual size cheaply.

For the full deep-dive (cut grades, fluorescence, certification specifics), we wrote a complete Diamond Education hub. Come back to it after the next two sections — they're more useful first.

Choosing a diamond shape.

Shape is the silhouette of the cut diamond — round, oval, pear, and so on. It's a deeply personal choice and one of the few decisions that's genuinely hard to undo (you can re-set a diamond into a different ring, but you can't change the diamond itself). Here are the ten shapes we cut and stock most:

Round Brilliant

Most popular. Maximum sparkle.

Oval

Elongating. Looks larger per carat.

Pear

Romantic. Vintage glamour.

Cushion

Soft pillow shape. Vintage feel.

Princess

Sharp, modern, geometric.

Emerald

Step cut. Architectural elegance.

Asscher

Octagonal step cut. Vintage glamour.

Marquise

Long, dramatic, finger-elongating.

Radiant

Brilliant + rectangular. Best of both.

Heart

Romantic, expressive, distinctive.

If you're not sure which shape your partner would choose, here's a useful proxy: look at her current jewellery and the necklines she wears. People who reach for clean lines and modern minimalism often gravitate to emerald, asscher, princess, or radiant. People drawn to softness and vintage charm tend toward oval, cushion, or pear. Round brilliant is the universal default — about 55% of all engagement rings still use it — and almost no one regrets it.

Pick a ring style.

The "style" is the architecture of the ring itself — the setting around the diamond. This is where most couples get stuck because there are dozens of options and they all sound similar. Here are the twelve we craft most often, with an honest read on who each one suits.

Still not sure? Book a free 30-minute design consultation with our master jeweller. We'll talk through your partner's style, your budget, and sketch a few directions in the room with you. No pressure to buy.

Choosing the metal.

The four metals you'll consider: 18ct yellow gold, 18ct white gold, 18ct rose gold, and platinum. Here's the truth about each:

The honest take

If you can stretch to platinum, do. It's the most durable, holds claws and bezels longer, and never needs rhodium-plating. If platinum is out of budget, 18ct white gold looks identical for the first 18 months and is a third less expensive — but factor in the replating cost as a small ongoing maintenance.

Yellow and rose gold are both having a strong moment again. Rose gold is particularly flattering across all skin tones and pairs beautifully with morganite and salt-and-pepper diamonds for couples who want something a little less conventional.

One mistake to avoid: don't mix metals between the engagement ring and the wedding band unless the design genuinely calls for it. They sit beside each other every day. Mixed metal stacks can look lovely with deliberate styling, but accidental mixing usually doesn't.

Getting the size right — without giving it away.

Ring sizing is the part that catches most surprise-proposers off-guard. Here's how to handle it:

If you're proposing as a surprise

Don't try to guess. Get one of these instead:

• Borrow a ring she already wears on the same finger. Pop it onto a piece of paper, trace the inner circle, and bring the tracing to us. We'll reverse-engineer the size to within a quarter-size.
• Use our free ring sizer. A flexible plastic sizer that goes anywhere in Australia in plain unmarked packaging. Slips on like a real ring and locks at her exact size. Order a free ring sizer.
• Get a friend to help. A close friend or her mother can usually figure it out without raising suspicion. Pretend it's for "a piece of jewellery you're researching".
• Just ask us. If you genuinely can't figure it out, propose with a temporary placeholder ring (or a beautifully-presented note) and bring her in for the real fitting after she says yes. It's becoming the most common approach for couples who want to choose the final ring together anyway.

If you're proposing together

Easiest. Visit any of our showrooms in Melbourne, Sydney, Brisbane, or Perth and we'll size her in person, no guesswork.

For Australia, ring sizes run F (very small) through Z+3 (very large). The average for Australian women is M – N, and the average for Australian men is S – T. We've written a complete Ring Size Guide if you want all eight sizing methods in detail.

Certification & ethics.

Every diamond Monroe Yorke sells is independently certified, and every diamond is sourced under the Kimberley Process. Here's what that actually means and why it matters:

What certification proves

An independent gemmological laboratory has graded the diamond on cut, colour, clarity, and carat — and recorded that grading on a unique certificate that follows the diamond for life. The two labs we trust: GIA (Gemological Institute of America — gold standard for natural diamonds) and IGI (International Gemological Institute — gold standard for lab-grown diamonds).

If a jeweller can't show you a certificate from one of these labs, walk away.

Conflict-free

The Kimberley Process is the international scheme that prevents conflict diamonds (also called "blood diamonds") from entering the legitimate trade. Every rough diamond traded internationally must come with a Kimberley Process certificate proving its country of origin and clean supply chain.

We go a step further. Our natural diamonds come from audited mines in Botswana, Canada, and Russia. Our lab-grown diamonds are produced in renewable-energy facilities. See our full conflict-free policy.

What "ethically sourced" should actually mean

Beyond conflict-free, watch for: traceability (can the jeweller name the mine?), environmental responsibility (is the mine restoring the land?), and fair labour (are mine and workshop workers paid living wages?). We can answer all three for any stone we sell.

Lab-grown or natural?

This is now the question we get asked most. Here's the unbiased answer:

How to actually choose

Choose natural if: you value provenance, you're investing for the long term, you want the strongest resale value, or the symbolism of "billions of years old" matters to you.

Choose lab-grown if: you want a bigger or higher-quality stone for your budget, you prioritise minimised mining impact, or you simply don't care about origin and want maximum value.

There's no wrong answer. We sell both, certify both, warranty both. About 60% of our customers in 2026 are choosing lab-grown, up from 35% two years ago — the trend is real.

Custom or ready-made?

Most of our engagement rings are ready-made designs that you customise in metal, diamond shape, and centre stone. About one in four customers chooses to go fully custom — designing a ring from scratch with our master jeweller. Here's when each makes sense.

Ready-made (~75% of customers)

You browse our existing engagement ring collection, pick a design you love, choose your metal and centre diamond. The whole ring is then hand-crafted to your specs. Timeline: typically 4 – 6 weeks. Lower price, lower risk of "not what I imagined".

Fully custom (~25% of customers)

You start with an idea, a sketch, a Pinterest mood board, or an heirloom you want re-set. Our master jeweller designs the ring with you over two or three sessions, you approve a CAD render, then we hand-craft it from the metal up. Timeline: 6 – 8 weeks. About 15 – 25% more expensive than equivalent ready-made.

If you need a ring sooner than these timeframes, please get in touch — we've delivered in under two weeks when needed, and we'll always tell you upfront whether your timeline is achievable.

When custom is genuinely worth it

• You have a specific design in mind that doesn't exist commercially. Toi et moi rings, asymmetric settings, vintage reproductions, integrating an heirloom stone — these are custom territory.
• You want family stones reset. Grandmother's diamond into a new band. We do this regularly and it's some of our most meaningful work.
• You want it engraved or personalised in a meaningful way. Hidden engravings on the inner band, fingerprint patterns, milestone date markings.

If you're considering custom, book a free 30-minute design consultation. No commitment — we'll talk through your idea and quote.

The proposal moment.

You've found the ring. Now what? Here's what we've learned from ten thousand-plus Australian proposals.

If it's a surprise

• Pick a place that means something — not the most expensive place. Where you had your first date, where you walked in the lockdowns, where you proposed to move in together. Significance beats grandeur.
• Hire a discreet photographer if you can. $400 – $800 in a major Australian city. The photos will outlast everything else.
• Practice opening the box smoothly. Sounds obvious. Most people fumble it.
• Tell one person where you'll be. A safety net in case anything goes sideways with logistics.
• Insure the ring before you leave the house. See After "Yes" below.

If you've decided together

Increasingly common, and there's nothing less romantic about it. The decision to spend your lives together is the proposal — the ring is just the artefact. Many "couples-first" proposals still include a moment, just one both partners knew was coming.

The ring box

Every Monroe Yorke ring ships in a hand-finished walnut box with our signature gold inlay, in a velvet pouch, in a matching outer carrier. If you'd prefer a smaller, pocket-friendly travel box for the proposal itself, we include one at no charge — just ask when ordering.

What to do after she says yes.

Photos, hugs, calls. Then, in the next week or two:

• Insure the ring. Most home and contents policies cover up to $1K – $2K of jewellery as standard — anything above that needs to be specifically scheduled. Get a separate jewellery rider with a reputable insurer for $40 – $120/year per $5K of value. Use the appraisal we provide with every ring.
• Get the resize done within 60 days if needed. Free for the first resize.
• Set a cleaning routine. Soak in warm soapy water and gentle-brush every 4 – 6 weeks. Bring it in for a complimentary professional clean and inspection every 12 months — included for life.
• Start thinking about the wedding band. Most couples buy theirs 6 – 9 months before the wedding. Whether you stack with the engagement ring or wear them apart is up to you — we'll lay out matching options when the time comes.
• Don't wear it in the gym, the ocean, or while gardening. Sunscreen, chlorine, and grit are the three biggest day-to-day enemies of fine jewellery.

Five mistakes we see every week.

1. Buying based on carat alone. A 0.85ct diamond with Excellent cut and VS1 clarity will out-sparkle a 1.20ct with Good cut and SI2 every time. Cut is the multiplier.
2. Skipping certification to save money. Uncertified diamonds are a black box. The savings are illusory because you can't independently verify what you're getting, and you can't insure it confidently. Always GIA or IGI.
3. Buying from a jeweller who won't put their name behind the stone. Most of our customers (around 80%) buy online or over the phone — and that's completely fine, provided the jeweller selecting the diamond knows what they're doing. We hand-pick every diamond ourselves the same way we'd pick one for our own family: cut grade, light performance, real-world appearance, not just the certificate. Look for a 14-day return policy, full certification, and a real human you can ask hard questions of. If all three are there, where you buy from is far less important than who.
4. Underestimating the wedding band. A skinny, intricately-set engagement ring won't sit flush against many wedding bands. Plan the pair together. We always quote both, even if you're only buying one today.
5. Spending the maximum you can afford "to be safe". The most common regret we hear isn't "I should have spent more." It's "I should have kept some money aside for the honeymoon / the deposit / the wedding band." Leave room.
