Ring Size Guide
Amorelle rings are made to order, so the size you choose is the size we make. It is worth taking a moment to get it right.
Sizes we offer
Every made-to-order Amorelle ring is available in US sizes 4 through 10, including half sizes. If you need a size outside that range, speak to your jeweller when you request a quote and we will tell you what is possible for that design.
Measuring at home
Using a ring you already wear
- Choose a ring worn on the same finger you intend the new ring for.
- Measure the inside diameter across the widest point, in millimetres.
- Compare it against the chart below.
Using string or paper
- Wrap a strip of paper or a length of string snugly around the base of your finger.
- Mark where it overlaps and lay it flat against a ruler.
- That measurement is your finger circumference. Compare it against the chart below.
Size chart
| US size | Inside diameter (mm) | Circumference (mm) |
|---|---|---|
| 4 | 14.9 | 46.8 |
| 4.5 | 15.3 | 48.0 |
| 5 | 15.7 | 49.3 |
| 5.5 | 16.1 | 50.6 |

Things that change the answer
- Time of day. Fingers are smallest in the morning and after cold weather. Measure late in the day, at normal room temperature.
- Band width. Wider bands sit more snugly. If a design has a broad band, consider going up a half size.
- Knuckles. The ring has to pass the knuckle but not spin at the base. If your knuckle is noticeably larger, size to the knuckle and mention it to your jeweller.
If you are buying a surprise
Borrow a ring she already wears on that finger and measure it, or ask someone who would know. If you would rather not guess, tell us when you request a quote and we will talk it through with you.
Still unsure?

Design Story
Ondine takes her name from the water spirits of old European folklore. The centre stone sits at the middle of concentric rings that ripple outward like water disturbed by a single drop, each band alternating polished gold and pavé. The squared shank beneath keeps the ring from turning on the finger, so the ripples always face upward.
Diamond Details
A brilliant lab-grown diamond sits at the centre. Every finished ring is supplied with full IGI certification, so the character of your stone is always documented.
Specifications
- Centre stone: Lab-grown diamond or moissanite, round brilliant
- Setting: Concentric pavé and polished-gold halos on a squared shank
- Metal: Solid yellow gold, available in 14K or 18K
- Certification: Full IGI certification with every ring
- Made to order: Yes, produced individually on request
- Ring size: Available in sizes 4 to 10
Metal & Craftsmanship
Hand-finished by Amorelle's jewelers in solid yellow gold, in your choice of 14K or 18K. Each concentric band is polished separately so the rings stay distinct from one another rather than blurring into a single mass.

- Full IGI certification with every ring
Shipping & Production
Nothing is made before you order it. Standard production takes 10–14 business days, with more intricate custom work taking up to 21. Free insured FedEx Express shipping is available to eligible destinations. Delivery is generally estimated at 3–7 business days after production. Every ring arrives in luxury ring packaging.
Returns
Amorelle offers 30-day returns in accordance with our returns policy. Because every ring is made to order, please review the full policy for how it applies to personalized, engraved, or bespoke pieces before purchasing.
Custom Engagement Rings
Have a vision entirely your own? Amorelle specialises in custom engagement rings — book a private design consultation and we will bring it from sketch to reality.
Made to order in solid 14K or 18K gold. 18K carries more pure gold and has a warmer colour; 14K is harder and stands up slightly better to daily wear.
Where this design includes a centre diamond, that stone is lab-grown and certified by IGI, so its carat weight, cut, colour and clarity are documented rather than described. Small accent and pavé stones are not individually certified, which is standard across the industry.
Nothing is made before you order it. Standard made-to-order pieces are typically completed in 10 to 14 business days. More intricate custom designs may take up to 21 business days. We confirm timing with you before production begins.
Your ring is shipped insured, and we confirm the details of the shipment with you before it leaves us.
These timings are typical rather than guaranteed. If you are working toward a specific date, tell us at the start and we will be straight with you about whether it is realistic.
Most designs can be adapted — a different centre stone, a different shape, a different metal, a different band width. If this ring is close but not quite right, say so when you request a quote and we will tell you what is possible.
If you have something entirely your own in mind, our Custom Rings page explains how that works.
Warm water, a little mild soap and a soft brush every couple of weeks will keep the stone bright. Put the ring on after moisturiser and perfume, not before, and take it off for cleaning, swimming and the gym.
Our Jewelry Care page covers this properly, including notes on 14K versus 18K and on white gold plating.
