?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.

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.
