The Mercer Half Eternity Emerald Cut Diamond Wedding Ring
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.
Wedding Bands for Women — Frequently Asked Questions
The terms are used interchangeably in everyday conversation — both refer to the wedding ring worn alongside an engagement ring. In our two collections, we use 'women's wedding rings' to emphasize style and design vocabulary (vintage, modern, contemporary, distinctive aesthetic choices) and 'wedding bands for women' to emphasize the band form and function (construction, resizability, daily wear practicality, fit with engagement rings). Both collections share many of the same products; the angles serve couples thinking about their wedding ring choice from different perspectives. Most couples find their wedding band through both collections.
Half eternity bands carry diamonds across the visible top portion only (with solid metal underside); they can be resized in the future and cost approximately 30-40% less than equivalent full eternity bands. Full eternity bands carry diamonds around the entire circumference for maximum brilliance from every angle, but generally cannot be resized after diamonds are set. From the wearing angle (looking down at your hand), half and full eternity look nearly identical. For couples confident their finger size is stable, full eternity offers maximum brilliance. For couples expecting potential finger size changes (pregnancy, weight changes, aging), half eternity is the practical choice with virtually identical wearing visual.
Only if your engagement ring's geometry requires it. Engagement rings with low-set centers (where the center stone projects significantly below the shank), distinctive shanks (twisted or sculptural), or geometric outlines (princess cut, baguette settings, art deco configurations) often need curved or chevron wedding bands to fit flush against them. Standard solitaire engagement rings with round or oval centers and refined shanks typically work with straight wedding bands. We can assess your specific engagement ring during the design conversation — ideally with the ring on hand or with detailed photographs — and recommend whether a straight, curved, chevron, or custom contoured wedding band fits best.
Yes, depending on the band's construction. Plain gold bands (Tanner family) can be resized within a wide range (4-5 sizes up or down). Half eternity diamond bands and partial-diamond bands can be resized within a reasonable range (2-3 sizes), though some diamonds near the resize area may need to be reset. Full eternity diamond bands generally cannot be resized because diamonds run around the entire circumference. We discuss resizability during the design conversation; if future sizing flexibility matters, we recommend half eternity, partial-diamond, or plain band constructions. All resize work on rings we've crafted is handled through our New York workshop.
Comfort fit construction refers to the interior shape of the wedding band — the inside surface that contacts the finger. Comfort fit bands have a slightly rounded (convex) interior that sits smoothly against the finger; standard fit bands have a flat interior that contacts the finger with more surface area. Most modern wedding bands (including the Tanner family) use comfort fit interior because it's smoother for daily wear and easier to slide on and off, particularly when the finger is slightly swollen. Comfort fit doesn't affect the exterior of the band — only the interior surface. Both fit styles work for daily wear; comfort fit is preferred by most wearers for its smoother feel.
Wedding band thickness (the dimension going from interior to exterior, not the width going around the finger) typically ranges from 1.3mm to 2.0mm for women's wedding bands. Thinner bands (1.3-1.5mm) read refined and lightweight. Thicker bands (1.7-2.0mm) read substantial and more durable. The choice depends on band width — narrower bands often pair with thinner thickness, wider bands often pair with thicker dimension for proportional balance. Thicker bands hold up to daily wear slightly better than thinner ones but the difference for most wearers is minor with proper care. We discuss thickness during the design conversation based on your width preference and daily wear patterns.
Yes — many wearers do, particularly during work, gym activities, gardening, or when traveling. Wedding bands designed in this collection read as complete rings on their own; you don't need to wear the engagement ring for the wedding band to look right. Some wearers eventually move the engagement ring to a different finger or wear it only for special occasions while wearing the wedding band daily. The wedding band's daily-wear-readiness is one of its primary functional qualities. For couples expecting to wear the wedding band on its own frequently, choose a design with distinct visual character (not just one designed to nest against the engagement ring).
White gold is naturally a slightly warmer, cream-toned alloy. Most white gold jewelry is plated with rhodium (a platinum-family metal) for a brighter, cooler white finish. The rhodium plating wears off gradually with daily contact — typically becoming noticeable after 2-3 years, depending on wear patterns. Without rhodium, white gold reveals its underlying warmer color, which some wearers see as 'turning yellow' (it's actually the natural white gold color showing through). Rhodium replating restores the bright white finish; we offer this service for any ring we've crafted. Some wearers prefer letting the rhodium wear naturally and embracing the warmer underlying color as the band ages.
Wedding bands in this collection are made-to-order in approximately 2-3 weeks from when your order is placed. The crafting process includes alloying the metal, forming the band, hand-setting any diamonds, and final finishing. Plain Tanner bands typically finish in 2 weeks; eternity bands with many diamonds may take the full 3 weeks; curved and contoured bands take 2-3 weeks. Custom wedding band designs take 3-4 weeks from design approval. Interior engraving adds approximately 1 week to any timeline. For wedding date deadlines, confirm timeline during the order conversation.
Yes — all wedding bands carry a lifetime warranty against manufacturing defects. The warranty includes free prong tightening, setting maintenance, finish restoration (polishing or refinishing), annual cleaning, and rhodium replating service (for white gold). Resizing is offered at modest cost (typically $75-$150 depending on size adjustment and band complexity). Diamond replacement, if a diamond is lost, is handled at the cost of the replacement diamond. We maintain records of every ring we craft to support warranty and service work indefinitely. Damage from misuse (severe impact, intentional alteration, exposure to harsh chemicals) is not covered, but normal wear and manufacturing-related issues are.
