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.
