The Tristan Diamond Eternity Ring

The Tristan is a floating diamond eternity ring with 0.875 carat of round diamonds prong-set around a 2mm high-profile band. A floating diamond band where each stone reads suspended in space — shared prongs the only thing holding the diamonds in continuous rotation.
Regular price$ 1,995.00

Width
Color

The Tristan uses shared prongs between adjacent diamonds so the metal between stones disappears visually — each diamond reads as floating in space rather than seated in metal. Around the 2mm high-profile band, this construction maximizes the visible diamond and minimizes the visible metal, producing an eternity ring of light rather than of structure.

As a floating diamond eternity ring, the Tristan reads more delicate and modern than a conventional channel or bezel eternity band. The 0.875 carat total weight is distributed across small floating stones rather than concentrated in fewer larger ones.

Metal Options 14K Yellow Gold, 14K White Gold, 14K Rose Gold, 18K Yellow Gold, 18K White Gold, 18K Rose Gold, or Platinum. Sustainably sourced.

What does 'floating' diamond setting actually mean?

A floating diamond setting uses shared prongs between adjacent diamonds rather than a continuous channel or bezel. The prongs are minimal — typically a single small bead of metal between two diamonds — so visually the metal between stones disappears and each diamond appears to be held in space rather than embedded in a band. On the Tristan, the floating construction is applied around the full eternity band, producing a continuous line of diamonds that read as suspended rather than mounted.

Is the Tristan more delicate than the Taryn 7 stone wedding ring?

Both rings use shared-prong floating construction, but they're different products. The Taryn is a 7 stone wedding ring with diamonds across a partial portion of a 3.5mm band (medium profile, 0.25 to 1.5 carat options). The Tristan is a full eternity ring on a narrower 2mm high-profile band with 0.875 carat around the full circumference. The Tristan reads more delicate (narrower band, smaller diamonds) and as an eternity ring (full coverage). The Taryn reads more substantial (wider band) and as a wedding band with diamonds on the top.

Will the small diamonds in a floating eternity band stay secure?

Floating diamond settings with shared prongs are generally secure for daily wear, but the construction is more open than a channel or bezel setting, which means there's slightly more risk that an individual diamond could loosen over decades. The benefit is that more light reaches each diamond from every angle, producing more brilliance per stone. An annual professional inspection catches any loose prongs early. For couples who prioritize visible brilliance over maximum mechanical protection, the floating setting is the design choice.

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 details
  • Adding gemstones or diamonds
  • Selecting your preferred metal type and color

The Tristan Diamond Eternity Ring

A floating diamond setting is what you get when the diamond matters more than the metal holding it.

The Tristan uses shared prongs between adjacent diamonds around a 2mm high-profile band — the prongs minimal, the metal between stones visually disappearing. The result is an eternity ring where the diamonds appear suspended in space rather than mounted in metal, with light reaching each stone from above, below, and around. The 0.875 carat total weight runs continuously around the band, distributed across small stones rather than concentrated in fewer larger ones. The narrow 2mm band keeps the ring close to the hand and pairs naturally with detail-rich engagement rings or as part of a stack. In white gold or platinum the floating effect reads strongest; in yellow gold the warm metal contrasts the suspended diamond line. As a floating diamond eternity ring, the Tristan is the choice when the diamonds should read as light rather than as structure.

The Tristan joins a Lisa Robin tradition of floating diamond eternity rings designed for couples who want maximum brilliance and minimum visible structure.

Design Process

The Lisa Robin Wedding Band Experience

A thoughtful process designed to bring clarity and confidence to the creation of your wedding band.

Our collection is intentionally edited — each wedding band design reflects a distinct point of view, with proportions and details that set it apart from what you've likely been seeing online.

When something here resonates, the decision tends to feel clear.

From there, we guide you in refining the details to align the design with your preferences.

Once you've chosen your wedding band, you'll select the core elements that define the design:

  • Metal type
  • Natural or lab-grown diamonds (if applicable)
  • Finger size
  • Optional engraving

If your wedding band will be worn alongside an engagement ring, we can help you evaluate how the proportions and overall profile will sit together and feel over time.

These decisions are focused and straightforward — so you can move forward with clarity.

If you'd like to adjust your diamond wedding ring, we guide you through a thoughtful refinement process — ensuring any changes support the overall balance and feel of the design.

Common refinements may include:

  • Adjusting band width or profile
  • Refining diamond size or spacing
  • Subtle modifications to improve pairing or wearability

Each change is considered within the context of the full design, so the final ring feels cohesive and intentional from every angle.

For custom refinements, we provide renderings for review before crafting begins — so you can move forward with complete confidence.

Every custom wedding band is hand-crafted to order based on your final selections.

  • Crafted specifically for your chosen design and refinements
  • No pre-made inventory or resizing shortcuts
  • Typical timeline: 2–3 weeks

If additional clarity is helpful before crafting begins, we can guide you through the next steps to ensure everything feels aligned.

What our customers say

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.

Diamond Eternity Rings — Frequently Asked Questions

A diamond eternity ring is a wedding band carrying diamonds around the entire circumference — the diamond setting continues uninterrupted from the band's top through the sides and underside back to the top again. This produces continuous diamond brilliance visible from every angle the ring is viewed. Eternity rings serve as wedding bands, anniversary rings, push presents, milestone celebration pieces, or standalone statement rings. The format symbolizes endless love (the unbroken diamond circle representing eternity) and remains one of the most distinctive wedding ring categories.
Full diamond eternity rings generally cannot be resized after diamonds are set. The continuous diamond setting around the entire circumference prevents cutting through the band, which is what resize work requires. This is the most important limitation of full eternity construction. Half eternity rings (with diamonds only across the visible top portion) and multi-stone wedding bands with metal spacing between diamonds CAN be resized within reasonable range (typically 2-3 sizes up or down). For couples concerned about future sizing flexibility, half eternity or multi-stone designs are the practical choice.
Eternity ring carat weights vary significantly by diamond cut and individual diamond size. Round brilliant eternity rings typically carry 1.00-3.00 carat total weight depending on diamond size. Emerald cut and oval eternity rings range 1.50-4.00 carat total weight. Statement eternity rings with larger individual diamonds (each 0.20-0.40 carat) can range 2.50-5.00+ carat total weight. Carat weight choice affects both visual presence (more carat = more substantial appearance) and cost (more carat = higher price). Specific carat weights for each eternity ring design are listed on the individual product pages.
An eternity ring is a specific type of wedding band — one with diamonds running around the entire circumference (full eternity) or across the visible top portion (half eternity). Not all wedding bands are eternity rings: wedding bands can also be plain gold (no diamonds), pavé bands (small diamonds across the top), curved or chevron bands shaped to nest with engagement rings, or designed bands with diamond accents. The term 'eternity ring' specifies the continuous diamond setting; the term 'wedding band' is the broader category that includes eternity rings and many other styles.
Full eternity offers maximum visible brilliance from every angle (diamonds visible whether the ring is at rest, tilted, or rotating) and the traditional eternity symbolism of unbroken diamond setting. Half eternity offers identical visual from the wearing angle (looking down at your hand), can be resized in the future, sits more comfortably against adjacent fingers (solid metal underside is smoother), and costs 30-40% less. For couples confident their finger size is stable, full eternity is the maximum-brilliance choice. For couples expecting potential size changes (pregnancy, weight changes, aging) or wanting cost savings, half eternity is the practical choice with virtually identical wearing visual.
Yes — eternity rings are commonly worn as wedding bands alongside engagement rings. The pairing decisions involve matching diamond cut vocabulary (brilliant cut eternity with brilliant cut engagement ring, step-cut eternity with step-cut engagement ring), metal coordination, and width proportion. The eternity ring's continuous diamond setting reads as substantial visual presence next to the engagement ring; couples drawn to maximum diamond impact on the hand often pair an eternity wedding band with their engagement ring. For couples whose engagement ring has substantial detail of its own, a more refined wedding band (pavé or narrow accent diamond) may pair more harmoniously than a full eternity ring.
Yes. All diamonds on eternity rings in this collection can be specified as lab grown or natural. Lab grown diamonds are physically and optically identical to natural diamonds but cost approximately 40-60% less for the same carat weight, color, and clarity. For eternity rings carrying significant total carat weight, the lab grown vs natural decision has substantial pricing impact — sometimes the difference between affordable and out-of-budget. Most eternity rings ordered today use lab grown diamonds; couples choosing natural diamonds typically do so for personal preference or for heirloom/investment considerations.
An east-west diamond eternity ring sets the diamonds horizontally across the band — pointed ends or longer axes running side-to-side rather than along the band's length. The east-west orientation is most distinctive with elongated diamond cuts (marquise, oval, emerald cut, pear) because the elongated shape produces visible horizontal pattern. Round brilliant diamonds don't have a meaningful east-west orientation. The {lk('Vashti', 'the-vashti-east-west-marquise-eternity-ring')} east-west marquise and {lk('Avery', 'the-avery-east-west-emerald-cut-eternity-ring')} east-west emerald cut demonstrate the format. East-west eternity rings read modern and architectural.
Diamond eternity ring pricing depends on diamond cut, total carat weight, diamond quality, and metal choice. Full eternity rings in 14K gold with lab grown diamonds (1.50-2.50 carat total weight) range $3,500-$7,000. Same designs in natural diamonds range $7,000-$15,000+. Higher carat weight rings (3.00+ carat total weight) and platinum construction increase pricing significantly. Half eternity rings cost approximately 30-40% less than equivalent full eternity rings. Specific pricing depends on your specifications — diamond origin, quality, individual diamond size, and metal choice. Pricing is confirmed during the design conversation.
Because full eternity rings cannot be resized after crafting, accurate sizing before ordering is critical. Best practice: get sized at a jeweler at the time of day and finger temperature when you'll typically wear the ring. Some considerations: fingers swell slightly in warm weather and shrink slightly in cold; fingers are often slightly larger at the end of the day than in the morning; eating salty foods or exercising can temporarily increase finger size. If you're between two sizes, the larger size is typically safer than the smaller — a slightly loose eternity ring is wearable, a too-tight one isn't. We provide sizing guidance during the design conversation; for couples within travel distance of Dayton, in-person sizing at the studio gives the most accurate measurement.
