The Anna Sapphire Cluster Engagement Ring

The Anna is a cluster arranged by reflection rather than by feel. Where the Chloe arranges its accents asymmetrically, the Anna mirrors them precisely across the sapphire center — each side identical to its twin.

The Anna mirrors marquise diamonds down each side of a sapphire center — leaves around a stem, white brilliance holding the frame while the blue anchors the middle. Choose a round sapphire for a center that sits calm and symmetrical, or a pear whose point sets the whole cluster growing in one direction. As one of the hardest gems after a diamond, the sapphire takes the daily wear this everyday setting invites.

A sapphire's blue comes from iron and titanium trading a charge in the corundum — why sapphires are blue.

How does the Anna cluster differ from the Chloe cluster?

The Anna mirrors its marquise accents across the sapphire center in precise reflected pairs, reading architectural and ordered. The Chloe scatters nine accents in an irregular arrangement composed by feel, reading vintage and hand-composed.

Should I choose a round or pear sapphire?

The setting is identical either way, so the choice is about how you want the center to sit. A round sapphire is self-contained — the mirrored marquise clusters read as leaves on both sides of a circle, and the ring looks the same from every direction. A pear points, and that point sets the cluster growing in one direction; worn with the tip toward your fingertip it draws the hand longer. Pricing doesn't change with shape: the setting starts at $2,795 in 14K gold and $3,195 in platinum, and your sapphire is quoted separately. In both shapes the cathedral supports hold the side clusters clear of the band, keeping the marquise tips off your finger. We can show you the same sapphire in both at a design appointment.

What color sapphire suits a cluster engagement ring like the Anna?

Sapphires come in nearly every color, and the Anna's cluster setting flatters saturated stones in any of them. A blue sapphire engagement ring is the most familiar, but the setting also suits vivid yellow, rich pink, or deep forest green.

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

Mirror Geometry, Translated into Botanical Form

Nature builds in symmetry more often than people realize — leaves matched along a central vein, petals counted in repeating groups, wings folding precisely against themselves. Mirror symmetry isn't ornament in those structures; it's the underlying logic. The Anna takes that as its starting point.

The sapphire at the center carries the rest of the design's color responsibility. Sapphires come in a remarkable range — blue in every saturation from midnight to teal, but also yellow, pink, green, orange, peach, and the rare padparadscha that sits between pink and orange. A colored gemstone engagement ring with a sapphire center is as much about which sapphire as about which setting: a deep teal reads cool against white gold, a soft peach warms against rose, a yellow sapphire glows against yellow gold. Most couples come to a sapphire engagement ring expecting one color and leave open to the range.

On the hand, the Anna reads dimensional rather than flat. The side clusters sit slightly elevated on their cathedral supports, catching light from multiple angles as the hand turns. Smaller than a halo, more architectural than a solitaire — the Anna joins a Lisa Robin tradition of cluster and botanical engagement rings designed for couples drawn to symmetry as a visible discipline.

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 (free for any ring we craft) 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 stones, or stones 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.
