How Long to Make a Custom Engagement Ring?

Most custom engagement rings take 4 to 6 weeks to make, from design consult to final delivery. Simple solitaires made custom can be ready in 3 weeks, while more intricate designs may take closer to 6 weeks.

Start early and choose a jeweler who communicates clearly. It is ideal to start the custom ring process 10 to 12 weeks before you need the ring. Starting early makes the entire experience more enjoyable and less stressful. It allows for more time to refine your design, gives you greater flexibility in diamond selection, and keeps all creative options open. With a comfortable timeline, you can focus on the details that matter most instead of worrying about deadlines.

If you’re planning a proposal or a big surprise, you’re probably wondering if you’ve got enough time to create something truly personal. The good news is a custom engagement ring is absolutely achievable with the right timeline and expectations. 

Whether you visit us in person or prefer to design your custom engagement ring online, Mikado Diamonds makes the process simple and personalized.

Want to know what’s realistic and how to make sure your ring arrives on time?

Below, I’ll break down each step of the process, what can slow things down, and how to stay ahead of schedule.

How Long Does It Take to Make a Custom Engagement Ring?

At Mikado Diamonds, the average custom engagement ring takes 4 weeks from consultation to delivery. This timeline may differ slightly based on the details of the ring.

Simple solitaires can be ready sooner, while intricate designs or multiple revisions may take a little longer. Starting early and working with a jeweler who communicates clearly will always make the process smoother.

If you are planning a proposal or a surprise, you are probably wondering if you have enough time to create something truly personal. The good news is that a custom engagement ring is absolutely possible with the right expectations and planning.

Below, we explain every step, from concept and CAD renderings to diamond selection and delivery, so you will know exactly what to expect, how long each stage takes, and how to stay on schedule.

What to Expect From a Custom Ring Timeline

At Mikado Diamonds, most custom engagement rings take 4 to 6 weeks to complete, depending on the design and materials.

• If you select a simple solitaire and an in-stock lab-grown diamond, your ring could be ready in about 3 to 4 weeks.
• If you choose a more intricate design, such as vintage-inspired detailing or bezel setting, expect closer to 4 to 5 weeks, especially if revisions are requested.

Can it be done in three weeks? 

Technically, yes, if the design is straightforward, the diamond is readily available, and every approval is immediate. It is possible, but not ideal if your proposal depends on a strict deadline.

If you’ve got a proposal date circled on the calendar, aim to start at least 10 to 12 weeks in advance. That buffer gives you time to make thoughtful choices, handle any curveballs, and truly enjoy the process.

What Goes Into Making a Custom Engagement Ring

Designing a custom ring is exciting, but each stage takes care and precision. Here is how the process typically works:

Step 1 – Consultation and Design Discussion

We can create a completely custom ring or one inspired by a design you have seen elsewhere.

The initial conversation can be as simple as emailing us a photo or calling to discuss ideas. We also offer virtual or in-person consultations.

The first step is selecting your center diamond, since our designers build the ring around its exact dimensions. Choosing the diamond is one of the most important steps. Whether you are looking for a 3-carat oval or a fancy-colored stone, the selection determines how the ring will be designed.

Once our Jewelry Consultants have confirmed all details, we provide a quote and estimated timeline.

Step 2 – Order Placement and Diamond Procurement

After your order is placed, we immediately secure your center diamond. Every custom ring is designed around the exact dimensions of that stone to ensure a perfect fit and balanced proportions.

Step 3 – Digital Renderings and Revisions (1 to 3 business days)

After the order is confirmed and the diamond secured, our designers create digital renderings (CAD models) that show the ring from every angle. These are typically ready within 1 to 3 business days.

You will review and approve the renderings to ensure everything looks exactly as you want. Two free revisions are included if changes are needed.

Quick approvals help keep your project on schedule.

Step 4 – Production and Setting (3 to 5 weeks)

Once the design is approved, production begins.

This stage includes casting the metal, polishing, and setting your diamond by hand.
Most rings take 3 to 5 weeks, depending on the complexity of the design and the type of metal. Certain styles, such as bezel-set diamonds, may require additional time.

Step 5 – Final Inspection and Delivery 

Before your ring ships, it goes through our full quality-control inspection. We check every detail, including stone security, finish, engraving, and sizing.

Rings ordered online are shipped via FedEx or USPS with signature confirmation and insurance. Free shipping is included for all engagement rings with upgraded shipping options available at checkout. It takes 1 to 3 days.

What Makes the Process Faster, or Slower?

Every custom ring has two timelines: the one you hope for, and the one that actually happens. Here’s what speeds things up, and what quietly slows everything down.

Factors That Speed Things Up

If you’re working on a deadline (a proposal trip, a specific date, or even a surprise), here’s how to stay ahead:

• Quick decisions and fast approvals: The single biggest accelerator is decisiveness. Clients who approve CADs or select stones right away move to the front of the production queue.
• Using in-stock diamonds: Rings built around diamonds already in inventory (especially lab-grown) avoid the sourcing lag.

Clear Timelines Help, but We Work in Order

While we love knowing your proposal plans, all projects are handled on a first-come, first-served basis. We don’t slow things down for “no rush” orders, and we generally can’t speed things up for last-minute requests.

What helps most is clear communication up front, especially if you're working toward a specific date. That way, we can let you know early if your timeline is realistic and guide you accordingly.

Common Bottlenecks to Avoid

Even with careful planning, a few common situations can extend the timeline. Here are the main ones to watch for and how to stay ahead:

• Unclear timelines. If you don’t have a target date, it’s easy for a project to move more slowly. Sharing your proposal date or ideal delivery window helps us prioritize and plan accordingly.
• Delays in approving designs. Waiting too long to approve renderings or request revisions can quickly extend production time. Prompt feedback keeps your ring on schedule.
• Special or rare stones. Unique shapes, large sizes, or fancy colors often require additional sourcing time. If you have your heart set on something specific, it’s best to start early.
• High-volume seasons. Spring and the holiday period are our busiest times. If you’re planning a proposal during these months, we recommend beginning the process sooner to ensure your ring is ready on time.

Custom vs. Ready-to-Ship: What’s the Tradeoff?

If you are short on time, you still have several options.

• Ready-to-ship rings can be shipped in 2 to 3 business days and often only require resizing.
• Semi-custom rings, which use preset designs with your chosen diamond, take 2 to 4 weeks.
• Fully custom rings take 4 to 6 weeks and allow for complete creative control.

The difference comes down to personalization versus speed. For many couples, the story behind a custom ring makes the extra time worth it.

Is it worth the wait?

If you're crafting something symbolic, something they’ll wear for the rest of their life, then absolutely.

A custom ring doesn’t just check a box; it tells a story. Just make sure you start early enough to enjoy the process instead of racing the clock.

We help you navigate that tradeoff. Whether you need something soon or want to go all-in on a fully custom design, we’ll guide you toward a solution that fits your timeline and your vision.

Proposal Planning: When Should You Start?

If there’s one thing I’ve learned after helping hundreds of clients plan custom rings, it’s this: your proposal date doesn’t move, but your ring timeline might. So let’s reverse-engineer your calendar the smart way.

It is ideal to start the custom ring process 10 to 12 weeks before you need the ring. Starting early makes the entire experience more enjoyable and less stressful. It allows for more time to refine your design, gives you greater flexibility in diamond selection, and keeps all creative options open. With a comfortable timeline, you can focus on the details that matter most instead of worrying about deadlines.

If you have a specific proposal date, work backward from that date.
For example, if you plan to propose in August, start by May or early June.

A few helpful guidelines:

• For holiday proposals between November and December, start by early October.
• For spring or summer engagements, begin no later than February.

If your proposal is approaching quickly, simplify your design choices. Choose an in-stock diamond and approve renderings promptly. Most importantly, have an open discussion with your Jewelry Consultant about your timeline so they can help you plan each step and ensure your ring is completed in time. 

With clear communication and realistic expectations, we can almost always meet your deadline.

What Clients Wish They Knew Earlier

• Start earlier than you think. Beginning the process 10 to 12 weeks before you need the ring keeps everything relaxed, allows for more creative design options, and ensures time for sourcing the perfect diamond.
• A larger budget does not necessarily make the process faster. Quick approvals and clear communication do.
• Always share your proposal date clearly. We would much rather be upfront about an unrealistic timeline than risk the disappointment of missing one.
• Sourcing isn’t always instant. Special cuts, fancy colors, or larger stones sometimes need to be ordered specifically for your design. Early planning gives you the widest selection.
• It’s worth the wait. A custom ring takes time because it’s made specifically for you. The result is a one-of-a-kind piece that tells your story.

How to Feel Confident About Your Custom Ring Timeline

Most custom engagement rings take 4 to 6 weeks from start to finish, though beginning 10 to 12 weeks in advance gives you the most flexibility and peace of mind.

Delays are rare when timelines and expectations are clear. With prompt communication and timely approvals, the process is smooth and enjoyable.

At Mikado Diamonds, we treat every ring as a once-in-a-lifetime piece, designed with precision, quality, transparency, and care.

FAQ: How Long Does It Take to Make a Custom Engagement Ring?

Still have questions about the custom process or your timeline? Our FAQ below covers the most common topics clients ask before starting their design.

What’s The Average Timeline For A Custom Engagement Ring? 

It takes us about 4 weeks to make most custom engagement rings. Complex designs or multiple revisions can push it to 6 weeks. 

Since every ring is unique, you'll get a custom timeline based on your specific design, materials, and requirements from us.

Can I Design My Custom Engagement Ring Online?

Yes. At Mikado Diamonds, you can design a custom engagement ring online from start to finish. 

The process begins with a call, email, or virtual consultation with a Jewelry Consultant, where we discuss your ideas, style preferences, and budget. From there, our team helps you select a center diamond, then creates detailed digital renderings (CAD models) for your approval. 

You’ll receive regular updates at every stage, from design to production to delivery. Many clients complete the entire process online, making it convenient, transparent, and personalized without ever needing to visit in person.

What’s The Fastest It Can Be Done?

Some custom rings can be made in as little as 3 weeks. If the design is simple, the diamond is in stock, and all approvals are immediate. This timeline is risky if you have a firm proposal date.

What Slows Things Down The Most?

Delayed approvals, vague deadlines, rare stone sourcing, and busy seasons (like holidays or spring).

When Should I Start If I Have A Proposal Planned?

It’s recommended to start at least 10 to 12 weeks before your date. 

What Steps Are Involved?

1. Design consultation
2. Diamond selection
3. CAD design & revisions
4. Production & setting
5. Final inspection & shipping

Can I Rush The Process If I Have A Deadline?

Yes. If you’re decisive, choose an in-stock stone, and work with a jeweler who handles everything in-house.

Is A Ready-To-Ship Ring Faster?

Yes. Most ready-to-ship rings just take 2 to 3 business days to be sized. Semi-custom options take 2 to 4 weeks. Full custom takes longer but offers the most personalization.
