There is no fixed amount you should spend on an engagement ring — a good working answer is to set a number you can pay for comfortably, then put the largest share of it into the diamond's cut, shape and carat, which is what the eye actually sees. The old "three months' salary" rule was a marketing line, not financial advice. With an IGI-certified lab-grown diamond, the same spend buys a noticeably larger, higher-quality stone than a mined one — so the real question is not "how much," but "where does the money go." Here is how to think it through.
How much should you spend on an engagement ring?
Spend what fits your life without debt. Most couples we work with land somewhere between HK$10,000 and HK$30,000 for a complete, certified lab-grown diamond ring — but the right figure is the one that leaves you calm, not stretched. A ring is the start of a marriage, not a test of it. Decide the ceiling first, then design within it. Because a lab-grown diamond costs a fraction of a mined stone of the same grade, that ceiling goes much further than most people expect.
Where the "three months' salary" rule came from
The idea that an engagement ring should cost two or three months' salary was popularised by a diamond-industry advertising campaign in the twentieth century. It was never a rule, a tradition, or a measure of commitment — it was a way to sell larger stones. Treat it as history, not a target. A thoughtful ring chosen within your means says far more than a number ever could.
What actually drives the price
Four things move an engagement-ring price, in roughly this order of visible impact:
-
Carat (size). Bigger stones cost more, and the price rises steeply at the "magic" weights like 1.00ct and 2.00ct. Choosing 0.90ct over 1.00ct, or an elongated shape that looks larger for its weight, makes your money go further.
-
Cut. The single most important factor for sparkle. A well-cut diamond outshines a larger, poorly cut one — this is where to protect your spend. Learn more in our 4Cs of lab-grown diamonds guide.
-
Shape. Round brilliants command a premium; ovals, cushions and emerald cuts often look larger per carat for less. See the diamond shapes guide.
-
Colour & clarity. You rarely need flawless. A D–F colour and VS clarity (or better) looks icy and clean to the naked eye without paying for perfection you cannot see.
Metal and setting matter too — a three-stone or pavé setting uses more diamond than a plain solitaire, and 18k gold costs more than 10k. Our settings guide breaks down how each style affects both look and price.
How lab-grown diamonds change the equation
A lab-grown diamond is chemically, physically and optically identical to a mined diamond — same hardness, same fire, same certification from labs like IGI. The difference is price: a lab-grown stone typically costs a fraction of a mined equivalent. That changes the entire conversation. Instead of compromising on size or quality to hit a number, you can hold quality high and stay within your number.
Here is roughly what different amounts buy in a complete, IGI-certified lab-grown diamond ring (1ct+ stones are IGI certified; D–F colour, VS clarity or better):
| What you spend (HKD) |
What it typically buys |
| HK$9,000–12,000 |
A clean 1.00ct solitaire in a classic setting — a beautiful, certified everyday ring. |
| HK$12,000–18,000 |
A larger 1.5–2.00ct solitaire, or a 1ct stone in a pavé or cathedral setting with extra detail. |
| HK$18,000–25,000 |
A 2.00ct centre, or a three-stone design where the side diamonds add real presence. |
| HK$25,000+ |
A 3.00ct+ statement stone, or a three-stone ring in 18k gold with matched ovals. |

A simple way to decide what to spend
Three questions settle most decisions:
-
What can I pay today, in full? That is your ceiling. Financing a ring you cannot afford is the one thing we would always advise against.
-
What does she actually wear? A petite hand and a minimalist wardrobe rarely want a 4-carat stone. Match the ring to the person, not the rule.
-
Where do I want the money to show? If size matters most, prioritise carat and an elongated shape. If sparkle matters most, protect the cut grade. You can have both with lab-grown — that is the point.

Our take
Set the ceiling first, choose lab-grown, and protect the cut. That order quietly settles the question of what to spend: you spend an amount you can afford on a stone that is certified, sizeable and brilliant, with nothing borrowed and nothing to prove. The "right" number is simply the one that lets you propose with a clear head — and every ring we make is crafted to order in solid gold around exactly that idea. Start with the engagement ring guide if you want the full picture before you set a figure.
Engagement ring spending FAQ
How much should I spend on an engagement ring?
Spend an amount you can pay in full without strain. There is no required figure — the "three months' salary" idea was advertising. Because a certified lab-grown diamond costs a fraction of a mined one, most couples get a complete, beautiful ring within a comfortable price range.
Is the three months' salary rule real?
No. It came from a twentieth-century diamond marketing campaign, not from tradition or financial advice. A ring chosen within your means is the better measure of a good start.
Do lab-grown diamonds look lower quality?
No. A lab-grown diamond is optically and chemically identical to a mined diamond and is graded by the same labs, such as IGI. The only meaningful difference is price, which is why the same spend buys a larger or higher-quality stone.
What should I prioritise if I am spending less?
Protect the cut grade first — it drives sparkle — then choose an elongated shape like oval or cushion that looks larger per carat. You can keep colour at D–F and clarity at VS without paying for flawless.
Should I finance an engagement ring?
We would not recommend going into debt for a ring. Choose a design within what you can pay today; lab-grown pricing usually makes that easier than expected. We are a jeweller, not a financial adviser, so weigh your own circumstances.
