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 Wedding Rings — Frequently Asked Questions

A full eternity wedding band carries diamonds around the entire circumference (top, sides, and underside). A half eternity wedding band carries diamonds only across the visible top portion (typically 180 degrees), leaving the underside in solid metal. The half eternity offers two advantages: it can be resized in the future (full eternity cannot, because the continuous diamonds prevent cutting through the band), and the solid metal underside is smoother against adjacent fingers. From the wearing angle looking down at your hand, a half eternity and full eternity look nearly identical. Half eternity bands typically cost 30-40% less than full eternity bands due to fewer diamonds.
Yes. Standard accent diamond quality on our wedding rings is VS-SI1 clarity in E-F-G color — high quality but not the maximum. You can specify higher quality (VVS clarity, D-E-F color) at increased pricing, or lower (SI1-SI2 clarity, H-I-J color) for cost reduction. For most accent diamonds in wedding bands (which are typically 0.01-0.05 carat each), the visual difference between standard and higher grades is minimal because the diamonds are too small to show visible inclusions or color tint. Most couples select the higher quality for engagement ring center stones rather than for wedding band accents. We discuss diamond quality during the design conversation.
Diamond wedding band carat weights vary significantly by design. Narrow pavé bands (1-1.5mm wide) carry 0.10-0.30 carat total weight. Standard half eternity bands carry 0.50-1.00 carat total weight. Full eternity bands carry 1.00-2.50 carat total weight depending on diamond size. Statement diamond wedding bands (like the Gabby at 0.90 carats) carry significant individual diamond weight. The choice depends on visual presence preference and budget — more carat weight produces more diamond brilliance and higher cost. Specific carat weights for each design are listed on the individual product pages.
Yes. Lab grown diamonds are physically, chemically, and optically identical to natural diamonds — they're real diamonds, just created in a controlled laboratory environment rather than mined from the earth. The crystal structure (carbon arranged in a diamond lattice), hardness (10 on the Mohs scale), optical properties (refraction index, dispersion that produces fire), and gemological grading (color, clarity, cut, carat) are identical between lab grown and natural diamonds. Lab grown diamonds are graded by the same gemological labs (GIA, IGI) on the same scales as natural diamonds. The difference is origin and price; lab grown costs approximately 40-60% less for the same specifications.
The choice depends on visual character preference and pairing with your engagement ring. Round brilliant diamonds produce maximum sparkle and pair coherently with most engagement ring styles. Step-cut diamonds (emerald, baguette, asscher) read architectural and pair best with step-cut center engagement rings. Marquise diamonds read distinctive and pair with marquise, oval, or pear center engagement rings. Princess cut diamonds read angular and modern. Oval diamonds read elegant and elongated. We confirm cut choice during the design conversation based on your engagement ring (if pairing) and visual preferences.
Half eternity and partial-diamond wedding bands can be resized within a reasonable range (typically 2-3 sizes up or down) — the resize work cuts through the band, adjusts the diameter, and rejoins. Some diamonds near the resize area may need to be reset depending on how much adjustment is required. Full eternity bands generally cannot be resized because diamonds run around the entire circumference, preventing the cutting needed for resize work. If future resizability matters to you, choose a half eternity or partial-diamond design rather than full eternity. We discuss specific design resizability during the design conversation.
Diamond wedding rings in this collection are made-to-order in approximately 2-3 weeks from when your order is placed. The crafting process includes sourcing diamonds in your specified origin (lab or natural), size, and quality; alloying the metal; forming the band; hand-setting each diamond; and final finishing. Eternity bands with many diamonds may take the full 3 weeks; narrow pavé bands typically finish in 2 weeks. Custom diamond wedding ring designs take 3-4 weeks from design approval. Engraving adds approximately 1 week to any timeline.
Diamond wedding ring pricing depends on diamond count, total carat weight, diamond quality (lab grown vs natural, VS-SI1 vs higher), and metal choice. Narrow pavé wedding bands in 14K gold with lab grown diamonds start around $1,200. Half eternity bands range $2,000-$4,000. Full eternity bands range $3,500-$8,000+ depending on diamond size and total carat weight. Statement diamond wedding bands with substantial individual diamonds (like the Gabby at 0.90 carats) range $4,000+. Lab grown diamonds reduce cost approximately 40-60% compared to natural. Specific pricing is confirmed during the design conversation.
Yes — many wearers choose to wear their engagement ring on one finger and diamond wedding band on another (often switching the engagement ring to the right hand after the wedding). Some wearers find this more comfortable than stacking the two rings together, particularly when the engagement ring has a substantial center stone that catches on adjacent fingers. The choice is personal and doesn't affect either ring's design. If you anticipate wearing your wedding band on its own (without the engagement ring) frequently, choose a wedding band design that reads complete and distinctive on its own rather than one designed primarily to nest against the engagement ring.
Yes. We can replace any lost diamond on a ring we've crafted. The replacement diamond is sourced to match the original specifications (lab grown or natural, same size, same color, same clarity), set in the same setting style, and finished to match the original ring. Diamond loss is rare with proper care and annual prong inspection (a free service we provide for any ring we've crafted), but if it happens, replacement work is straightforward. We maintain records of every ring we craft so the original specifications can be matched exactly. Contact us when a replacement is needed.
