How Long Does a Bespoke Engagement Ring Take to Make?
The Short Answer
For most bespoke engagement rings at Diamond Ateliers, the process takes four to eight weeks from the point of signing off on a design to having the finished ring in your hands. Add one to two weeks at the front end for the consultation and design process, and you're typically looking at six to ten weeks in total.
More complex designs — intricate pavé work, elaborate settings, unusual stone shapes, or designs that require multiple rounds of revision — can take longer. The most detailed pieces we've made have taken up to twelve weeks. Simple solitaire designs with a round or oval stone can sometimes be completed in three to four weeks if the diamond is in stock and decisions are made promptly.
The key takeaway: don't leave it to the last minute. If you have a proposal date in mind, work backwards from that date and add a two-week buffer for the unexpected.
Stage 1: The Initial Consultation (Week 1)
Every bespoke ring at Diamond Ateliers starts with a conversation. This is where you tell us everything: the style you have in mind, your budget, whether you're drawn to platinum or gold, whether you've seen anything that's inspired you, and what you know (or don't know) about diamonds.
If you come in with a clear brief and strong reference images, this stage can be completed in a single session of an hour or so. If you're less certain about what you want — which is completely normal, especially if this is your first time navigating fine jewellery — we might recommend a second conversation before moving forward.
By the end of the initial consultation, we'll have a working brief and a sense of the diamond specifications we're targeting. Most clients leave this session with a clear direction and a timeline for the next steps.
Stage 2: Diamond Sourcing (Days 3–10)
Once we have your specifications, we source diamond options that match your brief. This involves pulling from our network of suppliers — both for natural and lab-grown stones — and selecting the strongest candidates within your budget and priority list.
For lab-grown diamonds (which account for approximately 99% of our clients' choices), availability is excellent and we can typically present two to five options within a few working days. For natural diamonds with specific characteristics — particularly fancy shapes, strong fluorescence preferences, or unusual colour grades — sourcing can take a week or more.
We present options with full grading reports (GIA or IGI) and, where possible, actual images or videos of each stone so you can evaluate them before committing. Once you select a stone, it's reserved and the design process begins.
Stage 3: Design and CAD (Week 2)
After diamond selection, our design team creates a CAD (Computer-Aided Design) render of the ring. This is a photorealistic 3D visualisation that shows exactly how the finished ring will look — the metal colour, the setting style, the proportions, and the way the diamond sits in the head.
The CAD render typically takes three to five working days. When it's ready, we share it with you digitally and you have the opportunity to request adjustments: a slightly higher profile, a thinner band, different side-stone placement, and so on. Most clients go through one round of revisions. Some go through two or three. We iterate until you're completely satisfied before anything is manufactured.
This stage is where your input matters most. The more specific your feedback, the faster we can arrive at a design you love. Vague feedback (“I just feel like something's off”) takes longer to resolve than specific feedback (“can the band be 0.3mm narrower and the prongs slightly thinner?'”).
Stage 4: Production (Weeks 3–5)
Once the design is approved, production begins. The ring is manufactured in-house or with our trusted local workshop partners using a combination of casting and hand finishing. Here's what happens during this stage:
Casting. A wax model is created from the CAD file, then used to cast the ring in the selected metal (platinum, 18k white gold, 18k yellow gold, or 18k rose gold). The casting process takes two to four days.
Metal finishing. The cast ring is cleaned, filed, and polished. This is where the surface texture is established — high polish, satin/brushed, or a combination. This takes another two to three days.
Stone setting. The diamond is set into the finished ring by a skilled setter. Depending on the setting style — four-prong, six-prong, bezel, tension, channel, or pavé — this can take one to three days. More intricate settings (micro-pavé, for example) take longer than simple solitaires.
Final polishing and quality check. The finished ring is inspected under magnification, polished to its final finish, and checked against the design brief. Any imperfections are corrected before it leaves the workshop.
Stage 5: Handover (Week 6 Onwards)
When the ring is ready, we invite you in for collection. This isn't just a pick-up — we spend time with you to inspect the ring together, confirm the fit, and walk you through the care instructions. If a resize is needed (particularly common for surprise proposals), we arrange this on the spot or schedule it shortly after.
We also provide all documentation: the diamond grading report, a jewellery appraisal for insurance purposes, and a care card.
What Can Extend the Timeline?
A few things that commonly add time to the process:
- Indecision on the diamond — if you'd like to see more options or take longer to decide, the sourcing stage extends accordingly. There's no pressure from our side, but it's worth knowing this is often the longest single variable.
- Multiple rounds of CAD revision — each round of changes adds two to three working days.
- Unusual metal choices — some metal colours or alloys (such as 22k gold or palladium) require longer lead times for material sourcing.
- Rare diamond specifications — if you're looking for a very specific natural stone (unusual fluorescence, a particular origin, or a narrow colour/clarity window), sourcing can take several weeks.
- Peak periods — Valentine's Day and Christmas periods are busy. We recommend starting the process at least twelve weeks before these dates to avoid any risk.
Can It Be Done Faster?
Yes, in some cases. If you have an urgent timeline — a proposal date is approaching sooner than expected — we can often expedite certain stages. Simple solitaire designs with an in-stock stone and quick decision-making on the design can sometimes be turned around in three weeks.
We're always transparent about what's realistic given your specific brief and timeline. The best thing to do if you're time-pressed is to come in and have an honest conversation about what's achievable.
The Right Time to Start
Our honest recommendation: if you know a proposal is coming — even if you haven't fully decided on the design — start the conversation early. The initial consultation is completely free and has no obligation. Starting early means you can take your time on the choices that matter most, rather than rushing decisions you'll be looking at every day for the rest of your life.
Eight to twelve weeks before your intended proposal date is the ideal window to begin. Ten weeks is comfortable. Six weeks is workable for most designs. Anything under four weeks requires a frank conversation about what's possible.
