Custom Engagement Rings

You Have An Engagement Ring Vision, Now Let's Bring It to Life

Your engagement ring should be completely tailored to your style preferences. And ideally, it’s a design that you two have discussed and landed on together. Sometimes the engagement ring style you want is available in stock or made to order and can be in your hands in a matter of days and for that, you’ll find we have plenty of fantastic options.

But often what you’re looking for is harder to find. You might have a very specific concept in mind but need an experienced, trustworthy jeweler to help you execute it—and possibly improve on it with some unique creative flourishes or tweaks. The answer: a custom-designed engagement ring. 

And now that you've found Lisa Robin? The engagement ring design process couldn’t be easier.

Think of us as your very own private couture jeweler. We’ll build you a one-of-a-kind engagement ring from scratch—the best, most beautiful one within your budget. No criteria is too daunting and we are always up for the challenge, unlike traditional jewelers who often have neither the time nor the inclination to take on custom engagement ring design projects.


Well, much like with any custom jewelry design project, the cost of a custom engagement ring is determined by what you are trying to create. So, it depends. 

Generally the cost of a custom engagement ring is comparable to a similar ring with the same metals and like diamonds or gemstones. If you would like to modify a style shown on my website there is a small upcharge for new molds. To account for my design time, I charge a flat fee of $400 which is credited to the final quoted price.

Step #1
Book a Consultation

The first step is to book a private consultation, which takes place in-person, by appointment, at our studio in Dayton, Ohio or by Zoom.

How ever we meet, our design process is offered with expert guidance and personalized attention.


During your custom engagement ring design consultation, we’ll start by defining your style and narrowing your preferences. We’ll pull up pictures of rings, discuss what you like (and don’t like), and talk a bit about your lifestyle (if you’re always in garden, for example, or an avid surfer, there are some details to consider in terms of how high the ring sits on your finger and the durability of the metal you choose). I may sketch a few concepts as we move along. I’ll advise on diamonds and gemstones, and metals, and together we’ll land a design concept that ticks all the boxes. 

Step #2
Determine Your Budget

We appreciate that every client has a unique budget, and we strive to find the best options for you within your budget. Discover how to set a personalized budget for your ring.

How to Buy and Engagement Ring

Tips on how to buy the best engagement ring for you.


Once we land the design concept, We’ll source and show you a few diamond and gemstone options that meet your budget, size, and shape requirements. We will discuss the pros and cons of what each stone brings to the table in terms of quality and make selections from there. We can also use an heirloom diamond or other gemstone in the design. I love when family history lives on through jewelry!

Find the right ring size

We'll need a ring size to begin production. We can measure in the studio or find out options for virtual ring size measuring.


This is the magical time when the design we have in mind comes to life. Computer drawings are developed, to scale, to let you see a three-dimensional rendering of your engagement ring. If we haven’t quite nailed it, we can tweak the design till we have it just right.

CAD Rendering and Final Ring

Step # 6
Ring Crafting

We use final approved CAD drawings to a make handcrafted wax mold, which happens in our workshop. Then we have one of our best-in-class bench jewelers use the wax mold to cast the design in your chosen metal and set the diamonds in it. Careful hand-finishing and polishing of the design are the final steps, all overseen by our master jeweler, every step of the way. We are happy to keep you updated through the whole process.

Once your design is approved, it only takes 2-3 weeks for us to craft your engagement ring to perfection. When it's ready, we'll notify you and you'll be able to pick it up from our studio or we will express ship it to you. We guarantee that you'll be absolutely stunned by its exquisite beauty and you won't be able to take your eyes off it.
