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.
Regular price$ 2,995.00

Color
Shape

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.

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.

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.
