The Robin Diamond Side Stone Engagement Ring
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.

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
