Designing a Custom Engagement Ring: Every Customization You Can Choose
While shopping for engagement rings, couples want more than a beautiful ring, they want their ring. A custom engagement ring becomes a piece you design intentionally, from the diamond shape to the smallest hidden detail. Bespoke design transforms an engagement ring into a meaningful heirloom, reflecting both your style and your story.
At By Bonnie, custom design is a guided, personalized experience where every choice is crafted with expert precision and artistry. Whether you come in with inspiration or a blank canvas, your ring evolves through thoughtful curation, creative vision, and meticulous craftsmanship.
Step 1: Choosing Your Diamond, Shape, Ratio, and Size
Your diamond sets the tone for the entire design. Custom gives you the freedom to choose a stone that truly fits your aesthetic.
Shape
The shape defines the personality of the ring.
- Round: Timeless brilliance
- Oval: Elongated elegance
- Emerald: Architectural, modern
- Pear: Romantic, soft movement
- Radiant: Bold sparkle with crisp edges
Ratio
The length-to-width ratio impacts how the diamond looks on the finger.
- Ovals: 1.30–1.45 for most clients
- Emeralds: 1.35–1.50 depending on preference
- Pears: Balanced symmetry for maximum beauty
Ratio dramatically affects presence and finger coverage, which is why Bonnie hand-selects stones rather than relying solely on certificate numbers.

Step 2: Selecting Your Setting Style
The setting is the architecture of your ring, the part that determines how your diamond shines.
Popular custom styles include:
- Classic solitaire: Minimal, elegant, forever timeless
- Hidden halo: Adds sparkle without changing the top view
- Cathedral: Structural lift and graceful lines
- Tulip or petal settings: Romantic, airy silhouettes
- Low-set designs: Perfect for an active lifestyle
Each style can be built around your diamond’s proportions, ensuring balance and long-term durability.

Step 3: Choosing Your Metal & Band Width
Metal plays a key role in the final look and durability of your ring.
Metals offered:
- Platinum: Most durable metal, perfect for prong
- White Gold: Cool, bright, modern
- Yellow Gold: Warm, rich, classic
- Rose Gold: Romantic and soft
- Mixed Metals: Platinum prongs + gold band = ideal synergy
Band width options:
- Delicate: 1.6–1.8mm
- Classic: 2.0–2.2mm
- Bold: 2.5–3mm+
Band width should complement your hand shape, diamond size, and personal style, a decision Bonnie guides every client through.
Step 4: Pavé Style & Hidden Personalization
Custom design lets you add details only a trained eye, or your partner, might notice.
Pavé options:
- French pavé: Angled, bright, and dimensional
- Micro pavé: Dainty and seamless
- U-cut pavé: Vintage-inspired and sculpted
Hidden personal touches:
- Peekaboo gemstones (ruby, sapphire, diamond)
- Hidden halos
- Diamond bridges
- Engraved messages
- Two-tone prong structures
- Symbolic design elements
These subtle details make your ring meaningful from every angle.
