How to Get Started Making a Custom Engagement Ring

Hello, and welcome! Creating an engagement ring can be one of the most exciting parts of the proposal—especially when craftsmanship is the heart of the project.

When we talk about craftsmanship, we’re thinking in terms of design, uniqueness, creativity, and of course—beauty. Let’s walk you through how it all begins.

The process of making a custom engagement ring is simple, creative, and fun. It really comes down to three key steps:

Step 1: Choose the Stone Type, Shape, and Size

Step 2: Pick the Setting – Solitaire, Halo, Accent, or Side Stones

Step 3: Select Your Metal – 14kt, 18kt, Platinum, or Palladium

Let’s start with step one.

Step 1: Stone Type, Shape, & Size

Find out what you like by exploring the type of center stone, then shape, and finally size.

Stone Type:
Start by deciding between a diamond or gemstone center. You might lean toward a diamond (because hello—it sparkles), or you may want something more unique and symbolic like a ruby, sapphire, or emerald.

• Red for passion and romance
• Blue for the vastness of shared exploration
• Green for nature, new beginnings, and growth

Want to go even more unique? Explore stones like Teal Sapphire, Colombian Emeralds, or Mozambique Rubies—each with its own story and rarity.

Stone Shape:
This defines the ring’s personality. Popular shapes include Oval, Radiant, Teardrop, and Round. But if you’re looking for something truly one of a kind, explore Asscher Cut, Kite-Shaped, or Hexagonal stones. The uncommon shapes are often the ones people never forget.

Stone Size (Carat vs. MM):
Let’s be honest—"big" is subjective. Instead of focusing solely on carat weight, we recommend paying attention to millimeter dimensions. A 3-carat oval can range widely in shape and face-up size. One might appear long and slender; another, short and bold.

Pro Tip: The mm dimensions matter more than carat weight when it comes to achieving that perfectly proportioned, custom engagement ring look.

Once your stone is selected, you're ready for step two.

Step 2: Choose Your Engagement Ring Setting

Now it’s time to decide how you want to showcase your stone. This is where the design process gets fun.

You can explore options in our unique engagement ring collection for women or get inspired by browsing anywhere that sparks ideas. Settings include:

• Solitaire (timeless and clean)
• Accent or Side Stones (adds sparkle and frame)
• Three-Stone Settings (symbolic, elegant)
• Halo / Hidden Halo (creates a larger visual impact)
• Cluster Rings (artful and unconventional)

If you want the center stone to command attention—go with a Solitaire. If you’re drawn to designs that build drama and flow toward the center, a Halo or Three-Stone Setting might be perfect.

There are also architectural setting details—claw, bezel, cathedral, and basket—which influence things like how flush your ring sits with a wedding band or how much light hits the diamond. We’ll help you with those once we start customizing your piece.

Step 3: Metal Type – Color & Quality

Last, choose the metal that will frame your design.

We offer high-quality options in:

• 14kt or 18kt Gold (available in White, Yellow, or Rose)
• Platinum
• Palladium
• Sterling Silver (note: not typically recommended for engagement rings due to softness, but available)

If you’re unsure whether 14kt or 18kt is better for your ring, we’re happy to help you decide based on daily wear, color preference, and budget.
