Understanding CAD Images vs the Finished Engagement Ring: What to Expect

When you’re designing your own bespoke engagement ring, one of the first things you’ll probably see is a CAD image - a computer-generated design of your future ring. But these can be a bit confusing. Why does it look so chunky? Will the final ring really look like this? Let's go through the usual questions, so you know exactly what to expect.

What is CAD and Why Do Jewellers Use It?

CAD (Computer-Aided Design) Explained

CAD stands for "Computer-Aided Design," and it's basically software we use to create precise digital models of jewellery before we make it. Think of it as the blueprint of your engagement ring. It lets us visualise the design clearly and accurately before we go ahead with making anything.

Illustrative CAD designs are realistic-looking images that show roughly what your ring should look like when it's finished. You might sometimes see them on jewellery websites instead of product photography and not even notice!

 

Key Differences Between CAD Images and the Finished Engagement Ring

Why CAD Images Look Bulkier and Sharper

You might notice CAD images look quite sharp and a bit chunky. Don’t panic! The reason is, the digital model has to account for processes like casting and polishing that remove metal. This means your actual ring will end up much finer and more delicate than the CAD image suggests.

Shrinkage During Casting and the Importance of Extra Metal

During casting, your ring naturally shrinks by around 3%, so we build a little extra into the CAD design. This is completely normal and ensures your final ring isn’t too thin or weak after the casting stage.

Refining Claws: From Chunky to Elegant

People often notice the claws that hold diamonds or gemstones look large, square and flat in CAD images. Again, this is intentional. We start with more metal than needed to securely hold your stones in place, then carefully refine them into elegant, delicate claws at the finishing stage.

Polishing and Finishing: The Final Refinement

Polishing is the magic moment when your ring really comes to life. It removes excess metal, smooths edges, and gives your ring that gorgeous, shiny finish you’re looking forward to. So, remember - your CAD image is the "before," not the "after."

Common Pitfalls of Using CAD for Bespoke Jewellery

Technical Knowledge and Practical Jewellery Design

Just because someone can create a beautiful CAD design doesn't automatically mean it will translate well into a wearable piece. It's essential to work with someone who understands jewellery-making from start to finish, not just the digital bit.

Production Realities vs Digital Designs

Not everything that looks amazing on a computer screen works in real life. Some designs might look brilliant in CAD but end up being impractical or uncomfortable. I always make sure to talk it through with my clients so that they understand the process, and to avoid disappointment.

Misleading Perspectives: Zoomed-in CAD Images

Another common confusion comes from viewing CAD designs zoomed-in at huge magnifications. If your ring looks bulky, step back and ask to see the image closer to actual size.
Perspective makes a big difference and it’s often one of the biggest things to remember when looking at CAD images on your screen. A zoomed in detail on the side of a bespoke engagement ring will probably be a couple of millimetres in reality.

How to Effectively Use CAD in Your Bespoke Engagement Ring Design

Start with Sketches and Concept Development

I always recommend starting your design process with sketches and mood boards. This helps get the basics right before jumping into CAD. It ensures we're all on the same page about what you really want your ring to look like.

Collaborate with Experienced Jewellery Designers and Goldsmiths

Working closely with someone experienced in both CAD and traditional jewellery-making helps bridge the gap between digital images and the physical ring. This collaboration means fewer mistakes and a smoother process overall.

Questions to Ask Your Designer about CAD Designs

To ensure your CAD design matches your vision, ask these questions:

• Has the CAD designer understood my brief correctly?

• Does the design look balanced and practical when viewed at actual size?

• Have you made similar rings before, and can I see examples?

 

Benefits of Combining CAD with Traditional Jewellery Techniques

Precision Stone Setting and Detailed Design

CAD allows incredible precision, especially for intricate details and stone setting. When combined with traditional techniques, it gives you the best of both worlds - accuracy plus artistry.

Avoiding Common Mistakes Through Professional Guidance

Working with a skilled jewellery designer means they’ll spot potential issues early on. My experience means I understand the limitations and possibilities of each design, preventing costly and frustrating mistakes.

How CAD Can Save Time and Money in Jewellery Making

CAD can streamline the process by quickly creating accurate prototypes, reducing labour time, and minimising costly revisions. Done right, it saves you money while delivering the ring you really want.

Final Thoughts: Balancing Technology with Expert Craftsmanship

When CAD is the Right Choice for Your Bespoke Ring

CAD is fantastic, but it isn't always necessary for every design. It's brilliant for detailed, intricate rings and for precise stone placements. Sometimes though, simpler designs work better with traditional methods - so ask your jeweller what’s best for your idea.

Seeing Real-Life Examples to Set Accurate Expectations

Ultimately, nothing beats seeing real examples. Ask your jeweller for photos or actual samples of finished rings alongside their original CAD designs like the image below. This helps you set realistic expectations and reassures you that your ring will be exactly how you imagined it.

The CAD image looks much chunkier around the scalloped edge than on the finished ring. This is because the extra metal is worked to secure the diamonds and then polished to a refined edge. You can also notice that the diamonds look different, as CAD diamonds can’t quite live up to the real thing! SO if you’re disappointed with your CAD images, just remember the finished thing will look much more refined.

Creating your own bespoke engagement ring is exciting. By understanding how CAD fits into the process, you can relax knowing your final ring will look even better than that initial chunky CAD image suggests.
