Ring size guide
We make full US sizes. The bold letter is the exact UK match; the others fit best in that ring. The mm measurement is the true guide — between two sizes, round up.
| US | UK (best fit) | EU / circ. | Diameter |
|---|---|---|---|
| 3 | E, E½, F, F½ | 44.0 mm | 14.0 mm |
| 4 | G, G½, H, H½ | 47.0 mm | 15.0 mm |
| 5 | I, I½, J, J½ | 49.0 mm | 15.6 mm |
| 6 | K, K½, L, L½ | 51.75 mm | 16.5 mm |
| 7 | M, M½, N, N½ | 54.2 mm | 17.25 mm |
| 8 | O, O½, P, P½ | 57.0 mm | 18.1 mm |
| 9 | Q, Q½, R, R½ | 59.0 mm | 18.8 mm |
| 10 | S, S½, T, T½ | 62.0 mm | 19.7 mm |
Half or quarter US size? A .25 takes the size below (6.25 → 6); a .5 or .75 rounds up (6.5 or 6.75 → 7).
Measure at home
- Wrap paper or string around the base of your finger (not over the knuckle).
- Mark the overlap and measure the length in mm.
- Match it to the EU / circumference column. Or measure the inside of a ring you own and use the Diameter column.
Tip: measure at the end of the day, when fingers are largest. Between sizes? Size up.

How to measure
- Drape a string around your neck where you'd like the necklace to sit.

Ring size conversion
Every brand sizes a little differently, so we measured our own rings. We make full US sizes, and the chart below maps each one to UK and EU sizes. The bold letter is the exact UK match; the others in that row are the in-between sizes that fit best in that ring.
| US | UK (best fit) | EU / circumference | Inner diameter |
|---|---|---|---|
| 3 | E, E½, F, F½ (or smaller) | 44.0 mm | 14.0 mm |
| 4 | G, G½, H, H½ | 47.0 mm | 15.0 mm |
| 5 | I, I½, J, J½ | 49.0 mm | 15.6 mm |
| 6 | K, K½, L, L½ | 51.75 mm | 16.5 mm |
| 7 | M, M½, N, N½ | 54.2 mm | 17.25 mm |
| 8 | O, O½, P, P½ | 57.0 mm | 18.1 mm |
| 9 | Q, Q½, R, R½ | 59.0 mm | 18.8 mm |
| 10 | S, S½, T, T½ (or larger) | 62.0 mm | 19.7 mm |
The millimetre measurement is the true guide — US, UK and EU are just labels that approximate it. Between two sizes? Round up.
Measure with string or paper
- Wrap a strip of paper or string snugly around the base of your finger — not over the knuckle.
- Mark where it overlaps.
- Lay it flat against a ruler and measure the length in mm.
- Match that number to the EU / circumference column above.
Measure a ring you own
- Take a ring that already fits the right finger well.
- Measure straight across the inside, in mm.
- Match it to the Inner diameter column above.
Necklace lengths
We currently offer our necklaces in 45 cm (18 in) and 50 cm (20 in). Here's where each length sits, so you can picture it before you choose.
| Length | Inches | Where it sits |
|---|---|---|
| 40 cm | 16 in | Choker — sits at the base of the neck |
| 45 cm | 18 in | Our most popular — rests on the collarbone |
| 50 cm | 20 in | Sits just below the collarbone — easy to layer |
| 55 cm | 22 in | Falls on the upper chest |
Bold lengths are the sizes we offer. 16 in and 22 in are shown for reference.
How to measure
- Take a piece of string and drape it around your neck where you'd like the necklace to sit.
- Mark the spot and measure the length against a ruler.
- Compare to the chart above. Layering two pieces? Choose lengths about 5 cm (2 in) apart so they sit nicely.
Bracelet sizes
The right bracelet fit leaves a little room to move comfortably. Measure your wrist first, then check the guide below.
How to measure your wrist
- Wrap a strip of paper or string around your wrist, just below the wrist bone (where a bracelet naturally sits).
- Mark where it overlaps and measure in cm — that's your wrist size.
- For a comfortable fit, add about 1.5–2 cm to your wrist measurement.
| Wrist measurement | Fit |
|---|---|
| 14–15 cm | Petite |
| 15–16.5 cm | Small / Average |
| 16.5–18 cm | Medium |
| 18–19.5 cm | Large |

Beautiful earrings! The color of the stone seems slightly different in real life but that’s expected due to screen settings etc.
Was perfrect necklace that matched my emerald green satin dress for a wedding!
Beautiful pieces of jewellery. Both the necklace and the earrings feel of high quality.
I purchased this as a birthday gift for my sister, its so much more beautiful in person!
Looks lovely! Got it as a present for partners birthday and she really likes it.
Beautiful necklace just as pictured
Zgodne ze zdjęciem. Jak w opisie
The necklace and earrings were lovely but not quite the right colour for my outfit. Returning was so easy and the seller was really responsive.
Very pretty! Looked exactly like picture!
super beautiful and durable ! love it.
looked absolutely amazing and was a wonderful gift!
My girlfriend love it, thank you!
Fanstic necklace and earrings and both items are stunning
seller was super kind when I accidentally ordered 2 instead of one and refunded it.
Beautiful, finely made jewellery set! My friend will love it!
Great earrings, would definitely recommend
Fast delivery as described thank you
Beautiful earrings and arrived in great time despite the Christmas holidays - thank you!
Lovely necklace and quick delivery only issue is there doesn't seem to be an option on chain thickness (unless I missed that)
there decent for the price :)
The recipient loved this gift
Great item. Matched pictures perfectly
There was a complication with my order, nothing major, but the seller was so kind and quick to communicate with me (despite the ungodly hour I sent her a message). She helped me immediately get the problem resolved. The necklace was meant for Christmas but ended up being a great surprise gift for a night at the ballet. It’s absolutely gorgeous, I don’t think the pictures do it justice. My expectations were completely blown away and I couldn’t be happier.
Beautiful, gets me so many compliments
Beautiful necklace! item was even better than expected, recommend highly!
lovely seller, very helpful. love the items and enjoying wearing them. would recommend and would buy again. thanks x
The necklace and matching earrings were beautiful, came in cute/careful packaging, arrived on time, and made a great gift!
Looks amazing, i kind of want to keep it for myself now...was buying for a friend.
Einer der Ohrringe war defekt und wurde anstandslos ersetzt. Toller Service!
They fit well together! Beautiful
The items are beautiful and as described
The seller was communicative and pleasant to work with!
Exactly as described and I love them
