The Sophia Ruby Diamond Side Stone Engagement Ring

The Sophia Ruby is a side stone engagement ring with clustered trios of white marquise and round diamonds framing a red center. It's yours if you want bold color with a garden-shaped frame.

Other payment options available at checkout

Trios of round and marquise diamonds radiate from each side of the center, and a tapered band narrows toward it so your ruby stays the focal point.

Metal Options 14K Yellow Gold, 14K White Gold, 14K Rose Gold, or Platinum. Sustainably sourced.
Center Round ruby, selected for your ring
Side Diamonds White lab grown round and marquise diamonds in trios each side
Setting Diamond Total Weight 0.21 carat
Setting Diamond Quality Lab grown VS–SI1, E-F-G
Style Marquise accented side stone engagement ring
Setting Four rounded prongs
Band 1.2mm to 2.0mm
Setting Height Medium
Band Profile Tapered domed
Crafting Time Approximately 3-4 weeks

Setting starts at $2,775 in 14K gold and $3,175 in platinum. Your ruby center is selected for your ring and quoted to the carat weight you choose.

Can I choose a ruby other than a deep red for the Sophia?

Yes. Ruby runs from lighter pinkish red through the deep, slightly purplish red the trade calls pigeon's blood. Select your ruby on the site with pricing shown for each option, or we source a specific shade for you through a design appointment. The accent diamonds are colorless, so the setting doesn't change with the shade you choose.

How is the Sophia's side accent setting different from a halo ruby ring?

A halo rings the ruby in a continuous circle of accent diamonds, all the same shape and spacing. The Sophia gathers round and marquise diamonds in trios at each shoulder instead, so the frame reads as texture rather than a solid ring of brilliance: a quieter setting that still keeps diamonds close to the center.

Can the Sophia be worn with a wedding ring?

Yes — with a curved band. The tapered basket sits close to the finger, so a straight wedding ring can leave a gap beneath the ruby unless you prefer that space. A contoured band follows the setting's outline and sits flush against it, shaped to your ring.

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.

Refinement options include but are not limited to:

  • Adjusting the width or taper of the band (shank)
  • 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
Made to order — Your ruby engagement ring ships in 3-4 weeks, approximately Dec 11 to Dec 15

The Sophia Ruby Diamond Side Stone Engagement Ring

The Sophia Ruby Diamond Side Stone Engagement Ring places a red ruby between two clustered trios of marquise and round diamonds, angled outward from each shoulder like leaves around a bloom.

Red is the strongest color this setting takes. The ruby holds the eye first, and the white marquises frame it rather than compete. Ruby is durable enough for daily wear, so the color is a practical choice as well as a bold one.

Choose the Sophia in ruby if you want a ruby engagement ring with a botanical frame that feels warmer and more personal than a classic halo.

What our customers say about their Lisa Robin Gemstone 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.

More about Lisa Robin cluster engagement rings

A cluster engagement ring features multiple diamonds arranged together at the center of the ring, instead of a single solitary diamond. The diamonds can be evenly sized in a composition (like a sunflower or constellation pattern) or feature a slightly larger center diamond surrounded by smaller accents in a tight cluster. The cluster reads as one unified shape from a distance and reveals its individual diamonds up close.
A halo engagement ring has one center diamond surrounded by a continuous ring of smaller accent diamonds — the surrounding diamonds frame the center. A cluster engagement ring is composed of multiple diamonds working together at the center, often without a clear single anchor. Halos read more traditional and structured; clusters read more artful and composed. Both are popular Lisa Robin styles and we make both.
Cluster engagement ring settings start at $2,395. Final pricing depends on the total carat weight of the cluster, the cut and clarity of the diamonds, whether they're lab grown or natural, and the metal selected. Because clusters spread carat weight across multiple diamonds, they typically deliver more visual presence per dollar than a solitaire at the same total carat weight. We share itemized pricing for every quote.
Round diamonds are the most common because they pack tightly without leaving gaps in the cluster composition. Marquise, pear, and oval shapes can be incorporated as petals or asymmetric accents but require more design planning to balance the arrangement. Most cluster engagement rings in this collection use round diamonds, but the design isn't limited to round.
3-4 weeks from the day your order is finalized. Cluster work is precision metalwork — the prongs and bezels holding multiple small diamonds in a tight composition need to be cut to exact tolerances. We keep you in the loop at every stage: diamond matching, CAD review, casting, setting, and final inspection.
Yes. Lab grown diamonds work especially well in cluster engagement rings because matching color and clarity across multiple diamonds is easier with lab grown — they're produced under more consistent conditions. Lab grown clusters also tend to price meaningfully lower than natural clusters of equivalent total carat weight. Both options are available and we discuss the tradeoffs during the design process.
Yes. Choose any of our cluster designs (Chloe, Galaxy Cluster, Anna, and others) with your selected diamonds, metal, and refinements. We can adjust diamond sizes within the cluster, modify the arrangement pattern, and coordinate the engagement ring with a future wedding ring. For fully bespoke cluster designs, book a private design appointment to start.
They require slightly more attention. A cluster engagement ring has more individual diamond settings than a solitaire — each cluster diamond is held in its own setting, and individual settings can loosen over years of wear. The cluster's small spaces between diamonds can also collect lotion and skin oils. Weekly cleaning with warm soapy water and an annual professional inspection keeps a cluster ring looking and wearing well. The care isn't significantly different — just slightly more thorough than a single-diamond solitaire.
From across a room, a well-designed cluster reads as a larger single diamond rather than as multiple smaller diamonds. The grouped composition creates a visual focal point that the eye reads as one substantial diamond presence. Up close, the individual diamonds become visible and the cluster reveals its character — floral arrangement, scattered constellation, or geometric composition. This far-near visual quality is part of why clusters are popular: they offer the visual impact of a larger center at the cost of multiple smaller diamonds, which is significantly less expensive than a single equivalent-carat diamond.
Yes, and it's one of the most distinctive design directions we offer. Cluster construction allows multiple gemstones to coexist in the center — a sapphire center surrounded by diamond and morganite clusters, or a diamond center with sapphire and emerald accents. The composition can carry sentimental significance (birthstones of family members, anniversary gems, or gems chosen for color meaning) or be a purely aesthetic choice. Mixed gemstone clusters work particularly well in floral or scattered cluster arrangements. We design these during a private design appointment, where we discuss gemstone color, durability, and sourcing options.

Yes. Every Lisa Robin ring carries a lifetime craftsmanship warranty against crafting defects. If a defect in how your ring was crafted appears at any time, we will repair or replace it, at our option, at no charge. It covers crafting defects only, not wear and tear, accidental damage, theft, or the loss of diamonds or gemstones not caused by a defect. For care beyond the warranty, the JM Care Plan is the lifetime service option.
