The Short Answer
A custom-manufactured engagement ring typically takes four to six weeks from the moment the design is confirmed and the diamond is selected. Add one to two weeks for the initial consultation and design decisions, and you are looking at six to eight weeks from first contact to finished ring.
What Happens During Those Weeks
The manufacturing timeline is not idle time — it is a sequence of skilled craft steps, each of which contributes to the quality of the finished piece. Understanding what happens helps you appreciate why the process takes the time it does.
Week 1–2: Design and Consultation
This is where you and the jeweller align on the vision. You choose the diamond, the setting style, the metal, and the ring size. If the design involves custom elements — an unusual setting, a specific engraving, or a non-standard configuration — this phase may include CAD (computer-aided design) renderings so you can see the ring before it is made.
At Arete Diamond, this stage is collaborative. Our team helps you navigate the choices, answers questions about how different combinations will look and perform, and ensures that every detail is decided before production begins. Nothing is manufactured until you are satisfied with the design.
Week 2–3: CAD Modelling and Approval
For most custom rings, a digital 3D model is created. This allows you to review the design from every angle, check proportions, and request adjustments before any metal is touched. It is far easier — and less costly — to refine a digital model than to alter a finished ring.
Once you approve the CAD, the model is used to create a wax or resin prototype, which serves as the mould for casting.
Week 3–5: Casting, Setting, and Finishing
The ring is cast in the chosen metal — typically 18-karat gold or platinum. After casting, the piece goes through a series of hand-finishing steps: filing, polishing, and preparing the setting for the diamond.
The diamond is then set by hand. This is precise, skilled work. A master setter positions the stone exactly, secures each prong or bezel with careful pressure, and ensures the diamond sits level, centred, and secure. For pavé or halo designs, dozens of small accent stones are set individually — each one requiring the same attention.
Week 5–6: Quality Control and Final Polish
The finished ring is inspected for structural integrity, setting security, and finish quality. The diamond is checked to ensure it is firmly held. The band is polished to its final lustre. The ring is then cleaned, photographed, and prepared for delivery.
Why This Timeline Matters
It would be possible to rush the process. But rushing means cutting corners — less time for quality control, less precision in setting, less attention to finishing. The four-to-six-week timeline exists because each step is done properly, by people who take pride in the work.
This is not a delay. It is craftsmanship. The ring you receive at the end of this process was made specifically for you, by hand, to a standard that mass-produced jewellery cannot match.
How to Plan Around the Timeline
If you have a proposal date in mind, work backward:
- Eight weeks before: begin the consultation process. Choose your diamond and discuss design options.
- Six weeks before: confirm the design and approve the CAD. Manufacturing begins.
- Two weeks before: the ring should be complete and in your hands, giving you a comfortable buffer.
If you are working with a tighter timeline, let your jeweller know upfront. Some steps can be compressed modestly, but it is always better to start early than to rush.

Rush Requests and Tight Deadlines
Occasionally, clients need a ring faster than the standard timeline allows. Arete can sometimes accommodate shortened timelines depending on the design complexity and current production schedule. A simple solitaire in a standard metal will be faster to produce than a complex pavé halo in platinum.
If you are working against a deadline, the most important thing you can do is contact us as early as possible. Even if you are not ready to commit to a design, starting the conversation gives us time to prepare and advise on what is realistic.
