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.

What our customers say about their Lisa Robin Engagement Rings

I loved working with Lisa Robin! It was so easy to create exactly what I wanted. With some minor changes to Lisa's gorgeous styles, I had the perfect wedding ring to coordinate with my Lisa Robin Engagement Ring. Can’t wait to add another ring to my stack.

Our experience with Lisa Robin was delightful. We found our Lisa Robin engagement ring Instagram and then picked out and bought our wedding rings online. Every question we had was answered quickly. Lisa made us feel special and guided us in the right direction. When we got our rings, they were just what we wanted, expressing our style and love perfectly. We are so happy with how everything turned out.

Gender Neutral Engagement Rings and Wedding Bands — Frequently Asked Questions

Gender neutral rings are designed without the visual markers that traditionally distinguish 'men's' from 'women's' rings — meaning they don't lean toward extremely substantial widths (traditional masculine), extremely refined narrow widths (traditional feminine), heavy surface texture, floral motifs, or other visual elements that carry strong gender associations. Instead, gender neutral designs use middle-range widths (typically 3-5mm), balanced proportions, clean construction, restrained diamond placement, and design vocabulary that reads appropriately on any hand. Many rings designed without specific gender intent end up working as gender neutral by default; this collection curates those designs into a single browsable group.

Yes — this is one of the primary use cases for the gender neutral collection. Both partners can choose rings from the same design family with width or material variations adapting each ring to the wearer's hand. Common approaches: same design at different widths (4mm and 6mm Tanner, for example), same width in different metals (yellow gold and white gold), same design at identical specifications (when hand sizes are similar), or coordinated-but-distinct designs (each partner chooses a different ring that shares aesthetic vocabulary). The Tanner family is particularly suited for matched couples' bands because it offers five widths in the same design language.

No. Engagement rings and wedding bands are personal choices — some couples choose both, some choose only wedding bands, some choose only engagement rings, and configurations vary. There's no universal expectation that any particular configuration is correct. For same-gender couples or any couple preferring a streamlined approach, both partners wearing wedding bands only (without engagement rings) is a valid choice. For couples wanting more ring presence, both partners can wear engagement ring + wedding band. The configuration choice should serve the couple's preferences, not external expectations.

Yes — the design vocabulary in this collection is a starting point, not a constraint. Adjustments toward more traditionally masculine (wider band, more substantial profile, surface texture) or more traditionally feminine (narrower band, more refined proportions, more prominent diamond detail) can be made during custom design. Some couples want their rings to land at the gender neutral midpoint; others want their rings to lean slightly in one direction while remaining outside the traditional 'his and hers' binary. We discuss preferences during the design conversation. The flexibility is the point: the rings should reflect each wearer's individual identity rather than fitting predefined categories.

That's a valid choice. Couples don't need to wear matching or even coordinated rings — many couples choose rings that reflect each partner's individual style preferences. One partner might want a substantial textured wedding band while the other prefers a refined diamond eternity ring. The relationship doesn't require visual symmetry between the rings. For couples wanting some visual connection between distinctly different rings, options include shared metal (both rings in yellow gold, for example), shared engraving (matching dates or phrases inside both rings), or shared diamond origin (both rings using lab grown diamonds). We discuss approaches during the design conversation.

Yes. A gender neutral wedding band can be paired with any engagement ring, including engagement rings that lean more traditionally feminine or masculine. The pairing decisions involve standard considerations: matching diamond cut vocabulary, metal coordination, width proportion, and design language coherence. A gender neutral wedding band paired with a more characterful engagement ring creates a deliberate vocabulary mix — the engagement ring brings the design statement, the wedding band brings refined support. Many couples find this approach works well because the engagement ring carries the visual focal weight and the wedding band supports without competing.

Rings in this collection are made-to-order in approximately 2-4 weeks from when your order is placed. Wedding bands typically finish in 2-3 weeks. Engagement rings with center stones and substantial design typically take 3-4 weeks. Custom designs (where Lisa designs something specific to your vision) take 3-4 weeks from design approval. Interior engraving adds approximately 1 week to any timeline. For wedding date deadlines, confirm timeline during the order conversation.

Yes. All diamonds in this collection can be specified as lab grown or natural. Lab grown diamonds are physically and optically identical to natural diamonds — same hardness, same brilliance, same chemical and crystal structure — but cost approximately 40-60% less for the same carat weight, color, and clarity. Most accent diamonds in wedding bands today are lab grown; the visual difference is undetectable. Lab grown diamonds are particularly aligned with values around responsible sourcing for couples who prioritize that consideration. We discuss diamond origin during the design conversation.

Pricing depends on the specific design, metal choice, diamond specifications, and any customization. Plain Tanner gold wedding bands start around $700-$2,400 depending on width and karat. Diamond wedding bands range $1,200-$8,000+ depending on diamond count, carat weight, and design complexity. Engagement rings in this collection start around $2,500-$3,500 for solitaire designs and range to $15,000+ for more substantial designs with larger center stones. Custom designs vary based on specifications. Lab grown diamonds reduce cost approximately 40-60% compared to natural. Specific pricing is confirmed during the design conversation.

Yes. Design appointments are open to anyone planning engagement rings, wedding bands, or other significant jewelry. The appointment is a conversation about your relationship, your aesthetic preferences, your timeline, and your budget. Whether you're a same-gender couple choosing matched wedding bands, a nonbinary individual designing a single ring for yourself, an engaged couple of any configuration, or anyone wanting to discuss ring design — the appointment serves your specific situation rather than fitting you into predetermined categories. Appointments are available via Zoom, phone, or in person at the Dayton studio. The first appointment is complimentary.
