The Riley Marquise Side Diamond Engagement Ring

The Riley is a marquise side diamond engagement ring with a continuous flow of marquise-cut diamonds along each side of the band — each pointed diamond drawing the eye toward your center. A side stone engagement ring with directional movement, designed for couples who want brilliance with intention.
Regular price$ 2,475.00

Shape

The Riley marquise side diamond engagement ring sets marquise-cut diamonds in a shared-prong arrangement along the band on either side of the center — their elongated shape and pointed tips creating a directional quality that round side diamonds simply do not produce.

Each marquise diamond is distinct and visible, guiding the eye along the band toward the center diamond with a sense of movement and purpose. As a marquise accent engagement ring, the Riley's marquise diamond band feels designed rather than simply set.

Metal Options 14K Yellow Gold, 14K White Gold, 14K Rose Gold, or Platinum. Sustainably sourced.

What makes marquise side diamonds different from round side diamonds?

Round side diamonds create a uniform, continuous sparkle along the band. Marquise side diamonds add directional movement — the elongated shape and pointed tips guide the eye along the band toward the center diamond, creating a flowing, architectural quality. A marquise accent engagement ring reads as purposeful rather than uniformly bright.

How does the Riley's shared-prong arrangement contribute to the design?

A shared-prong arrangement uses one prong to hold two adjacent diamonds, which keeps the marquise diamonds close and continuous rather than separated by metal. The result is a marquise diamond band that reads as a flowing line rather than a series of isolated accents — each diamond contributing to a directional movement toward the center.

Why choose a directional diamond engagement ring with pointed shapes?

Most engagement rings use round or pavé side diamonds for steady, even brilliance. A directional diamond engagement ring uses pointed shapes — typically marquise — to create movement and visual flow. The eye follows the pointed tips along the band rather than reading the band as a uniform line. Couples drawn to directional designs usually want their ring to feel intentional and architectural rather than evenly decorative.

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.

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 Riley Marquise Side Diamond Engagement Ring

The marquise cut was created in 18th-century France, named for its resemblance to a smile and chosen specifically for its boldness. Two centuries later, the shape still carries that spirit — pointed, elongated, deliberately distinctive.

The Riley brings that quality into a marquise side diamond engagement ring where the pointed shape isn't decorative — it's the design language. A continuous flow of marquise diamonds surrounds the finger on both sides, each pointed tip drawing the eye toward your center diamond. As a side stone engagement ring with directional movement, the Riley reads as purposeful rather than uniformly bright. As a marquise accent engagement ring with shared-prong construction, the band feels like motion captured rather than diamonds simply set.

Wear it as a ring that points toward what matters. The Riley joins a Lisa Robin tradition of marquise and side stone engagement rings designed for couples drawn to expressive brilliance and purposeful design.
