How to Choose an Engagement Ring for Her
A practical guide to reading her style, finding the ring size discreetly, and making the right choice for a ring she will love wearing every day.
Start With What You Already Know
The best engagement ring choices come from paying attention, not from guessing. If you have been together for any meaningful period of time, you already have more information than you realise. The jewellery someone wears daily — the earrings they reach for every morning, the bracelet that never comes off — tells you a great deal about their aesthetic instincts.
Before looking at any rings, spend a few days simply noticing. What metals does she wear most? Are her pieces delicate or substantial? Does she gravitate toward classic shapes or something more distinctive? Does she tend to match her jewellery to outfits, or does she wear the same pieces regardless? These observations will narrow the field considerably before you look at a single ring.
Reading Her Style
Use the clues you already have to guide the direction:
If: She wears delicate, minimal jewellery
Consider: A simple solitaire — round or oval — on a thin plain or pavé band. Clean and understated.
If: She loves vintage or antique aesthetics
Consider: A cushion or emerald cut with a halo or intricate milgrain setting. Art Deco-inspired designs.
If: She prefers bold, statement pieces
Consider: A larger oval or pear shape, potentially with a halo, in a setting that elevates the stone significantly.
If: She is practical and active
Consider: A bezel or low-profile solitaire that sits close to the finger. Durable and comfortable for everyday wear.
If: She wears yellow or rose gold jewellery
Consider: Match her existing metal preference. A diamond in a warm metal setting is particularly striking.
If: She has no clear jewellery style
Consider: A classic round brilliant solitaire in white gold or platinum is timeless and universally flattering. It is never wrong.
Finding the Ring Size Without Asking
Ring size is the practical challenge that most people overthink. Here are the options in order of reliability:
- Borrow a ring she wears on her ring finger and have a jeweller measure it. This is the most accurate method by far.
- Trace the inside of that ring on paper and bring the tracing to your jeweller.
- Ask a close friend or family member who might know or be able to find out discreetly.
- Use the average — Canadian women's ring sizes most commonly fall between 6 and 7. If you have no other information, size 6.5 is a reasonable starting point.
Rings can be sized up or down after the proposal. This is standard practice and costs very little for a simple band. Do not let uncertainty about size delay the process or push you toward a ready-made ring that is otherwise not right.
The Diamond: What She Will Actually Notice
Most people focus their attention on carat weight — the size of the diamond. In reality, what people notice and respond to in a diamond is its overall appearance: how it catches the light, how it looks in the setting, how it suits the hand. A well-cut diamond of moderate carat weight will be more impressive than a larger stone with a poor cut.
For a ring being designed as a surprise, prioritise cut quality first, then choose a stone size appropriate for the setting style. Our 4Cs guide explains this in detail, but the short version is: never compromise on cut, and G or H colour in a VS2 clarity grade will look beautiful in any setting without overpaying for imperceptible quality differences.
All engagement ring stones at Aurela Diamonds are IGI certified and hand selected — you will not receive a stone that does not meet the grade on the certificate.
Frequently Asked Questions
How do I know what style of ring she wants?
The most reliable approach is observation. Look at the jewellery she already wears — does it tend to be delicate or bold, modern or vintage, minimal or detailed? Her existing pieces will tell you more than any survey. Saved Instagram posts and Pinterest boards are also useful if you have access to them. If you are genuinely uncertain, designing a ring together after the proposal is a legitimate and increasingly common approach.
What is the most popular engagement ring style for women?
Solitaire settings remain the most popular choice globally — a single diamond on a simple band. Within that, oval and round brilliant cuts are currently the most requested shapes. Halo settings (a ring of smaller diamonds surrounding the centre stone) are also very popular for those who want more visual presence. Ultimately, popularity is a starting point, not a guide — what matters is what resonates with the specific person wearing the ring.
How do I secretly find out her ring size?
The most reliable method is borrowing a ring she wears on her ring finger and having it measured by a jeweller. If that is not possible, trace the inside of the ring on paper and bring it in. If neither option works, the average women's ring size in Canada is between 6 and 7. Most rings can be resized after the proposal at minimal cost, so an estimate is workable.
Should the ring be a surprise or should we choose together?
This depends entirely on your partner. Some people have a very clear vision of what they want and would prefer to be involved in the choice. Others love the idea of a partner choosing something specifically for them. If you know her style well and she tends to appreciate thoughtful gestures, a surprise ring is a beautiful choice. If she has strong opinions about jewellery and you are uncertain, consider proposing first and designing the ring together — this has become increasingly popular and is a perfectly romantic approach.
