💶Ring Size Pricing

Our rings are individually handcrafted to your chosen size for a perfect fit and lasting strength.
Standard pricing applies to sizes H to R.

Larger sizes (above R): An additional €25 per finger size is applied to cover the extra precious metal required.
Example: Size X is six sizes above R → €25 × 6 = €150 extra.
Smaller sizes (below H): A €25 reduction per finger size applies to reflect the reduced metal used.
Example: Size E is three sizes below H → €25 × 3 = €75 less.

Unlike many jewellers who stretch or compress bands to change size — a shortcut that can weaken the ring and make future resizing more difficult — we craft each ring to its exact size from the outset, ensuring strength, comfort, and the ability to resize the ring comfortably in the future.

🔄 Can the Ring Be Resized Later?

Most rings can be resized, we will inform you before purchase if a ring can’t or has limited sizing options but all of our standard designs can be resized.
Plain bands: very flexible (+/- 2–3 sizes)
Diamond bands: flexible, typically +/- 2–3 sizes
Some designs (e.g. with split shanks or tension settings) may need more specialist work +/- 1–2 sizes

⚠️ Don’t Guess wildly!

Going too small may cause the ring not to fit at all
Size options might not reach the required
Going for an average size is generally safe
Ask our team for advice if you are unsure

💡 We offer free in-store ring sizing and post-proposal resizing services—so there’s no pressure to get it perfect first time.

❄️ Ring Sizing Tips You Might Not Know

Fingers shrink in cold weather and swell in heat or after physical activity
Try to size when hands are at a comfortable, neutral temperature
Wider bands feel tighter—consider going half a size up
Thinner bands may feel looser and are often more forgiving

🧠 FAQ – Quick Sizing Questions

Q: What if I guess the wrong size?
No problem! We’ll adjust it after the proposal—resizing is a quick and straightforward process in most cases.

Q: Can you size a ring before it’s set?
Yes—when buying from us, we can size the mount before the diamond is set for a seamless fit.

Q: Can you resize lab-grown or vintage rings?
Yes—though some vintage bands may need extra care. We’ll advise during your consultation.

🏁 Final Thought: A Ring That Fits and Feels Right

Finding the perfect ring size doesn’t have to be difficult. Whether you’re going for a surprise or choosing together, there are plenty of ways to get it right—or close enough to resize comfortably.

💍 Because the best engagement ring is one that fits the finger, the moment, and the story behind it.

What signifies an eternity ring and what occasions are they traditionally given?

An eternity ring, characterized by a continuous loop of diamonds, represents perpetual love and commitment. These rings are traditionally given during landmark anniversaries or to commemorate significant life events such as the birth of a child. Their circular design, with no beginning or end, symbolizes the infinite nature of love, making them a profound gift for moments that deepen a couple’s bond.

How do the designs of eternity rings for women vary and what should one consider when choosing?

The design spectrum for women’s eternity rings is vast, from minimalist bands with evenly spaced diamonds to lavish designs featuring 7-stone or 11-stone settings for a more opulent display. When choosing, it’s essential to consider the wearer’s lifestyle and personal style, the ring’s compatibility with other jewelry pieces, and the significance of the stone count, which can represent meaningful milestones or personal values.

How does the arrival of the first child influence the meaning and choice of an eternity ring?

The arrival of a first child is a transformative event in a couple’s life, often commemorated with an eternity ring that holds special significance. Opting for a 4-stone diamond ring can symbolize the family’s new structure, with each stone representing a family member. This choice imbues the ring with profound personal meaning, celebrating the family’s growth and the enduring nature of their love.

What are some innovative ideas for selecting a meaningful eternity ring?

For a truly unique eternity ring, consider bespoke options that reflect personal stories or milestones. This might include a 5-stone diamond ring to commemorate five years of marriage, or integrating various diamond cuts to represent different aspects of one’s relationship. Engraving dates, initials, or personal messages inside the band adds another layer of intimacy to the ring.

How do engagement, wedding, and eternity rings complement each other in a bridal set?

A bridal set consists of engagement, wedding, and eternity rings, each symbolizing a different chapter of a couple’s journey. Engagement ringr signifiy the proposal, the wedding band the commitment, and the eternity ring the ongoing love and shared life. When designed as a cohesive set, these rings not only fit together harmoniously on the finger but also reflect the continuity and growth of the relationship, with options ranging from simple 4-stone settings to more elaborate designs.

What factors contribute to the cost of an eternity ring and what price range is typical?

Several factors influence the price of an eternity ring, including the quality and size of the diamonds, the type of metal, and the complexity of the design. A simple 5-diamond ring might be more affordable, while a full eternity ring with larger diamonds or unique design features can significantly increase the price.

Prices can range broadly from €1000-10,000, making it important to consider budget alongside personal and aesthetic preferences.

What traditions are associated with eternity rings and how have they evolved over time?

Eternity rings have a rich history dating back several centuries, initially symbolizing eternal life and later, eternal love. Over time, their designs have evolved from simple bands to more intricate settings, incorporating a variety of diamond cuts and styles. Today, they are not only given as anniversary gifts but also to celebrate other significant milestones, such as the completion of a decade together or the achievement of a personal goal, making the choice of ring—from a 7-stone to a full eternity band—a deeply personal decision.

What guidelines should one follow when choosing an eternity ring to celebrate key milestones?

When selecting an eternity ring for a milestone celebration, consider the event’s significance and how the ring’s design can reflect this. For example, a 5-stone diamond ring might represent five years of marriage or the qualities of a strong relationship, such as love, commitment, trust, respect, and communication. The choice of metal, style, and diamond arrangement should align with the wearer’s preferences and lifestyle, ensuring the ring is not only a symbol of love but also a piece that can be cherished and worn daily.

What design elements distinguish an eternity ring, and how do they symbolize enduring love?

The defining feature of an eternity ring is its continuous loop of diamonds, which wraps around the entire band in a full eternity ring or is set across the top in a half eternity style. This unbroken circle of diamonds symbolizes unending love and commitment, making eternity rings a profound expression of lasting affection. The choice of design, from a 4-stone diamond band for simplicity and elegance to a more elaborate full eternity ring, reflects the depth and uniqueness of each couple’s love story.
