Wondering how much does a custom ring cost? If you’re thinking about designing a custom engagement ring, you’re probably wondering how it’s different from your average engagement ring shopping experience. Aside from the obvious differences between something designed and handcrafted just for you and something mass produced, the primary difference is value.

Many jewelry stores say that they “do custom” but they actually customize; changing details of an existing design. True custom rings are designed from scratch. Your very special ring starts from a hand drawn sketch and each element is considered, engineered, hand selected, and cast just for your one-of-a-kind ring. The cost of a custom engagement ring reflects this. With that in mind, each custom ring is an original; a unique combination of costs based on rarity of stones, value of metals, and complexity of design, but there are common elements that affect how much a ring costs. Read on to find out what price tier you’re in.

Custom Ring Design Cost:

$6,000 – $10,000

One of the top drivers of the cost of custom engagement rings is rarity and size of the center stone. Diamond engagement rings we have designed at this tier have a center stone under 1.0 carat like The Jess, or use a rough diamond like The Maria. Rings at this level tend to have understated metalwork and simple settings. A larger overall appearance can be achieved by adding a halo; accent stones around the center stone.

Custom diamond rings with a center stone or overall carat weight over 1.0 carat likely feature repurposed jewelry. When you incorporate family heirloom diamonds and already have your own center stone, it can potentially lower the overall cost of a custom ring.

Diamonds aren’t the only stone that can be repurposed, and we’ve designed rings that reuse other durable precious gemstones like sapphire, emerald, and ruby at this price point. A ring like The Brooke shows just how bold you can go with a repurposed gemstone.

Lab grown gemstones are a great option for our clients who want a higher carat center stone without the cost of a traditional, mined stone. A ring like The Carrie looks like a $15,000 ring, but with its lab grown ruby starts at $7,500.

How much is a custom engagement ring with a diamond over 1 carat? You’re going to have to move to the next tier of pricing. But you can get the look of a bigger diamond with moissanite, an ethical and budget friendly alternative that’s a fraction of the cost. The Laura and The Chelsea are two moissanite engagement rings that most would assume are 2 carat diamonds.

The Laura 2.0 carat moissanite engagement ring.

Custom Ring Design Cost:

$10,000 – $15,000

Graduating to this tier means you’ve made it to 1 carat diamond range or higher, congrats! This is what people typically envision with an engagement ring, and what the majority of our clients propose with. Rings like The Natalie and The Lauren show the average diamond size and setting detail you can get at this level.

Want more detail and less diamond? We’ve designed heftier settings with cut outs, accent stones, and diamonds under 1 carat like The Amber.

The Amber .9 carat diamond engagement ring with 1.65 ctw diamond accents.

Rings with 1.5 carat diamonds at this tier use lab grown stones, like The Andrea, The Alexandrea, and The Lindsay. Lab grown diamonds are about fifteen percent less than mined diamonds, so clients usually go lab grown for ethical reasons, or because they want a little more carat weight for their budget.

The Andrea 1.56 carat lab created diamond engagement rings.

Both rough diamonds and precious gemstones over 2.0 carats are possible at this price tier, as are larger diamond accent stones.

The Hannah 2.0 rough diamond engagement ring with diamond accent stones.

The Clara 1.4 carat blue sapphire engagement ring with diamond accents.

Custom Ring Design Cost:

$15,000 – $30,000

When you move into custom engagement rings at this price, you’re getting a bigger center stone, more detailed settings, and more carat weight in accent stones. You’ll see a higher prevalence of platinum, the most pricey of your metal options. Simply put, this is where the major bling begins.

From complex shapes to elaborate metal work, the more complicated the design, the higher the custom ring cost. We’ve designed highly embellished rings at this tier, like The Sherri, The Colleen, The Katy, and The Jacqueline.

Looking for 2 carat diamonds? Welcome to your tier. Engagement rings that cost over $30,000, like The Amanda and The Caroline are exemplary of this tier–2 carat rocks with minimalist bands. We have also custom designed more elaborate bands with slightly smaller diamonds like The Emily.

The Emily 1.91 carat diamond engagement ring with leaf detail and accent diamonds.

The cost of custom engagement rings with large, 5.0 carat plus precious gemstones like The Julie and The Morgan are in the $30,000 – $45,000 range, and both include over 1.0 carat in diamonds in their halos.

A custom engagement ring cost of over $50,000 pushes you into diamond carat weights well over the 2.0 mark. You’ll see multiple large stones with elaborate design like The Pamela with over 3.0 carats of diamonds and intricate milgrain bezel setting.

Moving toward the $100,000 mark is your route to getting a jaw dropping diamond like The Kristin. With it’s 4.07 carat center stone and beautiful diamond pave setting, this is your price tier if you’re looking for that devastatingly gorgeous, brilliantly sparkling, can’t-miss-it type of engagement ring.

Priorities and budget are different for everyone, and there are endless options for engagement rings. Custom isn’t for everyone, and if she knows the exact ring she wants, then get it! We are not the click-and-buy ring on the internet or the point-and-buy ring at the jewelry store, in fact we’re kind of the opposite. We’re also not the budget option, but because we are jewelry designers we can do our best to design around your budget. Some of our favorite tricks for trimming cost are to use repurposed stones, diamonds under 1 carat, or to use moissanite.
