Inside a Bespoke Ring: How CAD Design Works
A bespoke ring starts as a conversation and becomes a precise 3D model before any metal is touched. How CAD design works, and how to give a jeweller a brief they can work with.
A bespoke ring is one designed for you, rather than chosen from a catalogue. Today almost every bespoke ring begins life on a computer, in CAD (computer-aided design), which lets you see your ring in detail, and change it, before any metal is cast.
Step 1: the brief
Everything starts with a conversation. The more you share, the better the first design will be:
- Photos of rings you love (and ones you don't)
- The diamond: shape, approximate size, natural or lab-grown
- Metal colour and karat
- How the ring will be worn: hands-on job, sports, a wedding band beside it
- Your budget, honestly
Step 2: the CAD model
A designer builds the ring in 3D software, accurate to fractions of a millimetre. CAD checks things the eye cannot: that prongs are thick enough, that the diamond sits at a sensible height, and that a wedding band will fit alongside.
Step 3: renders and revisions
You receive photorealistic renders from different angles. This is the moment to ask for changes: a thinner band, a lower setting, a hidden halo, a different prong style. Small changes are quick in CAD and expensive once metal is cast.
Step 4: approval and making
Once you approve the design and quotation, the model is 3D printed in castable resin, cast in gold, then set, polished and inspected. Our bespoke pieces take about three to four working weeks from approval, then ship insured and tracked worldwide.
Why bespoke is not returnable
Because a bespoke piece is made only for you, it cannot be resold as stock, so it is excluded from standard returns. That is why the CAD stage matters so much: take your time and be sure. Learn more on our bespoke jewellery page.
What you can customise
The setting
Four or six prongs, claw or round tips, a bezel, a halo or a hidden halo under the stone.
The band
Width, profile, a split or twisted shank, plain metal or pavé diamonds.
The side view
Gallery details, a bridge under the stone or a tiny "peekaboo" diamond only you know about.
Personal touches
Engraving, a fingerprint, a birthstone set inside the band.
Bespoke or a customised design?
| Customised catalogue design | Fully bespoke | |
|---|---|---|
| Starting point | An existing design | Your ideas, sketches and photos |
| What changes | Metal, diamond, size, small details | Anything |
| Design time | None or minimal | About one to two weeks |
| Making time | About two to three working weeks | About three to four working weeks |
If a catalogue ring is 90% right, customising it is usually the quickest path. If you keep finding yourself saying "but", bespoke is worth it.
Questions to ask before you start
- How many rounds of revisions are included?
- Will I see renders with measurements in millimetres?
- Is there a deposit, and when does it become non-refundable?
- Which diamond report will come with the stone?
- What guarantee covers the finished ring?
Designs that started as ideas
How long does a bespoke engagement ring take?
Usually a week or two for design and revisions, then about three to four working weeks to make.
Is bespoke more expensive than buying a ready design?
Not always. With CAD, many bespoke rings cost a similar amount to comparable catalogue designs.
Can I use my own diamond?
Often yes. The jeweller will inspect and measure it first.
Can I bring my own sketch?
Yes. Sketches, screenshots and photos of rings you like are the best starting point for a designer.
Can I see a physical model before casting?
Some jewellers can print a resin prototype for you to try on, sometimes for a fee. Ask at the brief stage.
