Designing a ring is easier in the right order
Most people who want to design their own engagement ring feel overwhelmed. There are hundreds of options, and each seems to depend on the others. The good news is that the decisions fall into a natural order. Make them in that order and each one narrows the next.
Here are the six decisions we walk through with every client.
Decision 1: The shape of the centre stone
Start here, because shape sets the character of the whole ring.
- Round: maximum sparkle, classic, suits almost any setting.
- Oval: elongating, faces up larger for its weight, soft and modern.
- Emerald cut: clean, step-cut and architectural. Clarity matters more because the open facets show the inside of the stone.
To choose, look at photos of each shape on a hand, not floating on a white background. Notice which one you keep coming back to. If it is between emerald and oval, read our emerald vs oval comparison.
Decision 2: The setting style
With a shape chosen, decide how it is held and framed:
- Solitaire: the stone alone; quiet and timeless.
- Hidden halo: a secret row of small diamonds beneath the centre stone, seen from the side.
- Halo: a visible frame of small diamonds that adds sparkle and face-up presence.
- Pavé: small diamonds set along the band, for continuous light.
- Three stone: a centre stone with two side stones, often given meaning as past, present and future.
Then choose how the stone is held: prongs (more light, more classic) or a bezel (more protective, more modern). Our bezel vs prong guide covers the trade-offs. To see these styles drawn, browse the Setting Gallery.
Decision 3: The metal
We work in 18k white, yellow and rose gold.
- White gold is bright and modern, and it makes the stone look icy.
- Yellow gold is warm and classic, and it contrasts nicely with a white stone.
- Rose gold is soft and flattering on many skin tones.
If the ring will be worn with a wedding band later, think about whether the two metals should match. Many people choose to mix them on purpose.
Decision 4: The proportions
This is where designing your own ring really pays off, and where most ready-made rings make a choice for you. Consider:
- Stone size against finger. A 1 ct stone looks different on a size 5 finger than on a size 9. Our article on carat size on the hand and our guide to carat versus millimetres help here.
- Band width. A slimmer band makes the stone look larger. A wider band feels more substantial and suits larger hands.
- Setting height. A low setting is practical for active hands and catches less. A higher setting lets more light in and gives a more dramatic profile.
- Band profile. Flat, rounded or knife-edge profiles change how the ring feels and reflects light.
You do not need to know the numbers. Tell us how you want it to feel, and we will translate that into millimetres at the CAD stage.
Decision 5: The details
Small, personal touches make a ring yours:
- an engraving inside the band (a date, initials or a word);
- a hidden halo or a small accent stone under the centre;
- a slight twist or taper in the band;
- a matching wedding band designed at the same time, so the two sit flush.
Keep it to one or two details. A ring with one beautiful idea usually looks better than a ring with five.
Decision 6: Approval, twice
Designing your own ring is only safe if you can see it before it is made. That is why our process has two approval points:
- Line sketch. A hand-drawn sketch of the outline, proportions and details. Change anything you like.
- CAD confirmation. A precise 3D model built around your actual stone's measurements. Nothing is made until you approve it.
A 75% deposit begins the work and reserves the stone. The balance is due after you approve the CAD. If you cancel before production, the deposit is refundable. Because each ring is made for one person, we do not accept returns after production. One size change is free (you cover shipping). A change of up to 2 Hong Kong sizes is possible but requires a new band, charged separately; your centre diamond is reused. Everything is set out in our Custom Order Terms.
Common mistakes to avoid
- Choosing the stone before the shape. Shape first, then the specific stone.
- Chasing carat over cut. A well-cut smaller stone often looks livelier than a poorly cut larger one.
- Ignoring daily life. A tall setting is lovely but may not suit someone who works with their hands.
- Guessing the ring size. Use the ring size guide.
- Copying another brand's design. Use references for mood, not as a blueprint. Your ring should be your own.
A simple worksheet
Write one line for each decision:
- Shape: …
- Setting: …
- Metal: …
- Proportions (how it should feel): …
- One detail: …
- Date needed by: …
Bring that to a consultation and you will already be halfway to a sketch. See what a finished design document looks like on our design sheet page.
Ready to design?
Start with a setting if you know the look, or start with a diamond if the stone comes first. You will approve a line sketch and a CAD before anything is made.
How to give feedback on a sketch
A sketch review goes faster when the feedback is specific. Some phrases that help a designer:
- Proportion: "the stone should look a little larger against the band" or "the band feels too heavy".
- Height: "lower, so it sits closer to the finger".
- Line: "I want the band to taper towards the stone" or "keep the band straight".
- Detail: "add a hidden halo" or "remove the pavé from the underside".
- Feeling: "more delicate", "more architectural", "softer".
Avoid changing everything at once. If several things feel off, rank them, because a change to one often fixes another. A lower setting, for example, can make a band look less heavy.
What the CAD shows that a sketch cannot
The CAD is built around the real measurements of your stone and your ring size, so it reveals things a sketch only suggests:
- the exact height of the stone above the finger;
- the band width and thickness in millimetres;
- the position and size of each claw;
- whether a wedding band will sit flush against it; and
- how the ring looks from the side and from above.
Look at each view and imagine everyday life: gloves, knitwear, typing and holding hands. If something worries you, ask before approving. That is exactly what this stage is for.
Designing for the long term
An engagement ring is worn for decades. A few choices help it age well:
- Enough metal. A very thin band can look delicate at first but may wear and bend over time.
- Protective claws. Slightly heavier claws last longer.
- A size you can live with. Measure carefully, and remember that resizing has limits.
- A design that can accept a band. Even if you do not want a wedding band now, you may want one later.
Frequently asked questions
Do I need to be able to draw? Not at all. You describe the ring in words, references and feelings, and our designer draws it. Your job is to react: "a little slimmer", "lower", "more open".
How many changes can I make? Make as many as you need at the sketch stage. That is what it is for. At the CAD stage, changes are refinements to the approved concept.
Can I design the wedding band at the same time? Yes, and we recommend it if you want the two to sit flush. Designing both together avoids a gap between the bands later.
Can I use a stone I already own? Ask us. We will need to examine the stone and its measurements before confirming a design, because the CAD is built around the exact dimensions of the stone.
What if the finished ring does not fit? One size change is free (you cover shipping). A change of up to 2 Hong Kong sizes is possible but requires a new band, charged separately; your centre diamond is reused. Some designs, such as full pavé eternity styles, are harder to resize, and we will tell you at the CAD stage if that applies.
What happens to my sketch? It stays part of your ring's story. Many clients keep it with the ring's documentation.
