The Polaris Aquamarine Engagement Ring

The Polaris is scattered accent diamonds wandering around the aquamarine center in a constellation pattern. Nothing is in a row, nothing is concentric, and the spacing is the design.

How does the Polaris scatter differ from a typical side stone arrangement?

Accent diamonds wander around the center in irregular positions, each at its own height and angle to catch light from a different direction. Nothing is in a row, nothing is concentric, and the spacing is the design itself.

Why scatter the accent diamonds instead of placing them in a row?

Scattered accents at varying heights and angles reflect light from different directions simultaneously, creating brilliance that shifts as the hand moves rather than concentrating in one zone. The aquamarine center reads as the anchor; the scattered accents read as movement around it.

What is a constellation engagement ring, and how does it differ from a typical side stone setting?

A constellation engagement ring uses scattered, irregularly placed accent diamonds around the center stone — arranged the way stars are arranged, not the way ornament is arranged. The result is a setting that reads dimensional and shifting rather than uniform and 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.

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 diamond engagement ring ships in 3-4 weeks, approximately Aug 08 to Aug 12

A Constellation Around the Center

Stars don't sit in rows. The Polaris arranges its accents the way the night sky arranges itself.

The aquamarine at the center carries the rest of the design's color responsibility. Aquamarines come in a remarkable range — pale ice through sky to deep sea blue, with the rarer Santa Maria deep blue and Espirito Santo bluish-green at the saturated end. A colored gemstone engagement ring with an aquamarine center is as much about which aquamarine as about which setting: a pale ice reads delicate against white gold, a Santa Maria blue holds its own against yellow gold, a sea blue warms against rose. Aquamarine is softer than sapphire (7.5-8 Mohs), which makes the protective setting style here important — bezels and halos protect the stone from everyday wear. Most couples come to an aquamarine engagement ring expecting one color and leave open to the range.

On the hand, the Polaris reads dimensional rather than uniform — light reflects from multiple directions at once, creating a shifting brilliance that moves with the hand. The Polaris joins a Lisa Robin tradition of constellation and side-accented engagement rings designed for couples drawn to scattered light.

Frequently Asked Questions About Side Stone and Three Stone Engagement Rings

A side stone engagement ring features a center diamond with one or more accent diamonds set on each side. The side diamonds frame the center, add brilliance, and create a continuous line of sparkle across the finger. Side stone designs include three stone arrangements (one diamond per side), multi-diamond arrangements, and mixed-shape combinations.
A three stone engagement ring is a specific type of side stone design — one center diamond plus two flanking diamonds, three diamonds total, traditionally symbolizing past, present, and future. Side stone is the broader category, including arrangements with more than two side diamonds and graduated multi-stone designs. All three stone rings are side stone rings; not all side stone rings are three stone rings.
Yes. Side diamonds extend the visual width of the ring and draw the eye across the design, making the overall arrangement read larger than a solitaire of the same center diamond size. Tapered baguette sides have the most pronounced size-extending effect because of their long, narrow profile.
Side stone engagement ring settings in this collection start at $2,695. Paired with a 1 carat lab grown diamond center, side stone engagement rings start at approximately $3,595. Final pricing depends on the center diamond you choose, the side diamond shape and number, and your metal selection. We discuss diamond selection during the design process and share pricing transparently before crafting.
Each side stone engagement ring is made to order and ships in approximately 3-4 weeks from design approval. Custom side stone designs created from scratch typically take 3-4 weeks from final design approval, with the design phase preceding crafting.
Yes. Mixed-shape side stone designs are popular and beautiful — emerald cut center with round sides, oval center with tapered baguettes, cushion center with trapezoid sides, or other combinations. Mixed-shape designs are typically created during a private design appointment so Lisa can guide proportion and balance decisions.
Yes. Choose your center diamond shape and quality, your side diamond shapes and arrangement, your metal, and refine the proportions, band width, prong style, and wedding ring coordination. For mixed-shape designs or fully custom side stone arrangements, book a private design appointment with Lisa — virtual, by phone, or in studio.
Pavé is a setting technique where small diamonds are set close together with tiny prongs or beads, producing continuous sparkle along the band's shoulders. Individual pavé diamonds are typically under 0.04 carat each. Prong-set side stones are larger individual diamonds (0.10 to 0.30 carat each) held with traditional prongs, reading as discrete diamond focal points alongside the center. Pavé adds refined continuous brilliance; side stones add prominent diamond presence. Many designs combine both — pavé shoulders with one or two larger side stones flanking the center.
Often yes — a matched wedding band makes the engagement and wedding rings read as a deliberately designed set rather than two separate purchases. For pavé shoulder engagement rings, a refined pavé wedding band echoes the engagement ring's continuous diamond detail. For three stone or prominent side stone designs, a clean band sometimes works better as visual contrast against the engagement ring's diamond density. We design the wedding ring pairing during the engagement ring conversation, and many couples design both rings together for the best result.
No — and most couples choose not to match. Side diamonds are small and held in less visible settings; minor inclusions or slight color tint that would be visible in a 1+ carat center are invisible in 0.02 to 0.20 carat side diamonds. Our standard side diamond quality is VS-SI1 clarity in E-F-G color — high quality, not maximum. Most couples allocate budget toward center diamond quality and let side diamonds be standard. You decide where to compromise; we share itemized pricing on both center and side diamond options.
