The Robin Diamond Side Stone Engagement Ring

The Robin is a side stone engagement ring with shared-prong round diamonds along the band on each side of the center — a side diamond engagement ring with continuous brilliance and structured presence. A classic diamond engagement ring built for couples who want light moving through the entire design.

The Robin side stone engagement ring sets shared-prong side diamonds along both shoulders of a 3mm band — each prong securing two diamonds at once, creating a closer, more continuous line of light than a standard prong-set band produces. The side diamonds extend along the upper portion of the band; below that, the band is plain, so a wedding ring can sit flush while the diamond detail remains fully visible. As a shared prong engagement ring, the Robin reads structured rather than scattered, balancing brilliance with practical wear.

What is a shared-prong setting and how does it differ from pavé?

In a shared-prong setting, each prong secures two neighboring diamonds, holding them in a clean, continuous row. Pavé uses many tiny beads of metal to set much smaller diamonds densely across a surface. Shared-prong diamonds like the Robin's read as a defined line of distinct stones; pavé reads as an unbroken field of fine sparkle.

How far do the side diamonds extend along the Robin's band?

The side diamonds run along the upper portion of the 3mm band, on both shoulders toward the center. The lower part of the band is left plain, so a wedding ring can sit flush against it while the diamond detail stays fully visible from the top.

How are the Robin's side diamonds different from typical side stones?

Many side-stone rings place a few accent diamonds near the center. The Robin carries a continuous shared-prong line of side diamonds, 1.10 carat total, along the shoulders of a wider 3mm band, so it reads as more substantial and structured than a typical light scattering of side stones, while keeping the lower band clear for stacking.

Our guided approach to customizing each ring with intention and clarity.

Every Lisa Robin ring is made to order, which means your design can be thoughtfully refined — even when ordering online. Whether you're adjusting a detail or evolving the design, we guide you through each decision to ensure the final piece feels cohesive and entirely yours. The Robin diamond side stone ring can be beautifully modified to accept round, pear, marquise, cushion, emerald cut, radiant, asscher, or princess diamond shapes.

Design Refinements can be explored after your initial order, with any pricing adjustments clearly outlined and approved before crafting begins.

Available refinement options include:

  • Adjusting the width or taper of the band
  • Modifying or adding side diamonds for additional detail or presence
  • Changing the prong style (claw, round, double prong, etc.)
  • Adjusting the number of prongs for both aesthetic and structure
  • Refining the basket design for a different profile or overall look
  • Selecting your preferred metal type and color
  • Adapting the design to better coordinate with a wedding ring

The Robin Diamond Side Stone Engagement Ring

There's a difference between a band that has diamonds and a band that's defined by them. The Robin is the second.

A side stone engagement ring with shared-prong round diamonds at a substantial scale, the Robin extends brilliance along the upper three-quarters of a 3mm band. As a side diamond engagement ring with structured rhythm, each diamond remains distinct rather than dissolving into a uniform line — the eye reads individual diamonds, set with intention. As a classic diamond engagement ring in proportion and structure, the Robin reads composed and present without becoming ornate. The plain lower band keeps the ring practical for stacking and resizing.

Wear it as a ring where the brilliance moves with you. The Robin joins a Lisa Robin tradition of side stone engagement rings designed for couples drawn to integrated, deliberate brilliance.

Frequently Asked Questions About Side Stone and Three Stone Engagement Rings

A side stone engagement ring features a center diamond with one or more accent diamonds set on each side. The side diamonds frame the center, add brilliance, and create a continuous line of sparkle across the finger. Side stone designs include three stone arrangements (one diamond per side), multi-diamond arrangements, and mixed-shape combinations.
A three stone engagement ring is a specific type of side stone design — one center diamond plus two flanking diamonds, three diamonds total, traditionally symbolizing past, present, and future. Side stone is the broader category, including arrangements with more than two side diamonds and graduated multi-stone designs. All three stone rings are side stone rings; not all side stone rings are three stone rings.
Yes. Side diamonds extend the visual width of the ring and draw the eye across the design, making the overall arrangement read larger than a solitaire of the same center diamond size. Tapered baguette sides have the most pronounced size-extending effect because of their long, narrow profile.
Side stone engagement ring settings in this collection start at $2,695. Paired with a 1 carat lab grown diamond center, side stone engagement rings start at approximately $3,595. Final pricing depends on the center diamond you choose, the side diamond shape and number, and your metal selection. We discuss diamond selection during the design process and share pricing transparently before crafting.
Each side stone engagement ring is made to order and ships in approximately 3-4 weeks from design approval. Custom side stone designs created from scratch typically take 3-4 weeks from final design approval, with the design phase preceding crafting.
Yes. Mixed-shape side stone designs are popular and beautiful — emerald cut center with round sides, oval center with tapered baguettes, cushion center with trapezoid sides, or other combinations. Mixed-shape designs are typically created during a private design appointment so Lisa can guide proportion and balance decisions.
Yes. Choose your center diamond shape and quality, your side diamond shapes and arrangement, your metal, and refine the proportions, band width, prong style, and wedding ring coordination. For mixed-shape designs or fully custom side stone arrangements, book a private design appointment with Lisa — virtual, by phone, or in studio.
Pavé is a setting technique where small diamonds are set close together with tiny prongs or beads, producing continuous sparkle along the band's shoulders. Individual pavé diamonds are typically under 0.04 carat each. Prong-set side stones are larger individual diamonds (0.10 to 0.30 carat each) held with traditional prongs, reading as discrete diamond focal points alongside the center. Pavé adds refined continuous brilliance; side stones add prominent diamond presence. Many designs combine both — pavé shoulders with one or two larger side stones flanking the center.
Often yes — a matched wedding band makes the engagement and wedding rings read as a deliberately designed set rather than two separate purchases. For pavé shoulder engagement rings, a refined pavé wedding band echoes the engagement ring's continuous diamond detail. For three stone or prominent side stone designs, a clean band sometimes works better as visual contrast against the engagement ring's diamond density. We design the wedding ring pairing during the engagement ring conversation, and many couples design both rings together for the best result.
No — and most couples choose not to match. Side diamonds are small and held in less visible settings; minor inclusions or slight color tint that would be visible in a 1+ carat center are invisible in 0.02 to 0.20 carat side diamonds. Our standard side diamond quality is VS-SI1 clarity in E-F-G color — high quality, not maximum. Most couples allocate budget toward center diamond quality and let side diamonds be standard. You decide where to compromise; we share itemized pricing on both center and side diamond options.
