Searching for the perfect engagement ring but not sure where to start—or what to expect in terms of pricing? You’re not alone. At Theadore + Co, we know how overwhelming the process can feel, especially if it’s your first time. That’s why we created our lab-grown diamond ring builder — an easy-to-use tool that lets you design your own custom ring or simply explore different styles and price points.
Before you dive in, here’s a breakdown of the customisations available so you can feel confident navigating your options.
The Band
The band is the metal that wraps around your finger. At Theadore + Co, we offer four luxurious options:
- 18K Yellow Gold
- 18K White Gold
- 18K Rose Gold
- Platinum
If you’re shopping for your partner, understanding their metal preference is key. Not sure which metal is best? Check out this blog post where we break it down further.
You can also customise the shape and profile of the band—options include round, square, tapered, or pavé (with diamonds set into the band). You’ll also be able to select your preferred band thickness, from fine and dainty to bold and statement-making. These options will affect the pricing, and the builder updates costs in real-time so you can see how your choices stack up.
The Diamond
Now for the star of the show: the diamond. We offer all of the traditional stone shapes including, round, oval, marquise, emerald, cushion, radiant - to name a few.
Next is size, measured in carats. As you’d expect, a higher carat weight typically increases the price.
Then comes clarity and colour. We offer two diamond quality options in our builder. Clarity refers to the number and visibility of natural inclusions or blemishes in the stone. Our lab-grown diamonds are typically VVS1–VVS2 clarity, meaning they are extremely clean and nearly flawless to the naked eye—an excellent choice for brilliance and value.
Setting Style
Setting style refers to how many "prongs" you want to hug and secure the stone in place. We have a few different options; four, six, bezel or an open bezel.
Other Inclusions
Add personal touches to make your ring truly one-of-a-kind. Choose a hidden halo (a subtle circle of diamonds underneath the center stone for added sparkle), or change the orientation of the diamond. North-south is the traditional vertical setting, while east-west offers a more modern, horizontal twist. Oh, and we also offer complimentary engravements and birth stones on the inside of the band, for a unique touch. Just pop your request in the notes section!
Whether you're designing solo or building it together, the Theadore + Co ring builder is the perfect starting point. Explore styles, compare options, and bring your dream ring to life—no pressure, just possibilities.
