April Brown Diamond Birthstone Ring
Ring Size Guide
Golden Horn rings are listed in US sizes. Start with the finger you will wear the ring on and check the sizes available on that product page. A ring should sit securely at the base of your finger and pass over the knuckle without force.
UK, US and EU ring sizes
UK sizes use letters; US sizes use numbers. The EU/ISO convention is based on inside circumference in millimetres. For example, a 54 mm inside circumference is approximately EU 54. Regional charts and rounding can differ, so compare the actual measurement rather than assuming an exact conversion.
| UK | US | Inside circumference (mm) | Inside diameter (mm) |
|---|---|---|---|
| F | 3 | 44.2 | 14.1 |
| G ½ | 3.5 | 45.5 | 14.5 |
| H ½ | 4 | 46.8 | 14.9 |
| I ½ | 4.5 | 48.0 | 15.3 |
| J ½ | 5 | 49.3 | 15.7 |
| L | 5.5 | 50.6 | 16.1 |
| M | 6 | 51.9 | 16.5 |
| N | 6.5 | 53.1 | 16.9 |
| O | 7 | 54.4 | 17.3 |

The table is an approximate reference, not a measurement of every Golden Horn ring. Millimetre dimensions and UK/US equivalents follow Tiffany & Co.'s published size guide. Band width and handmade variation can affect fit. If your size is between available options, contact us with the product name and your measurement before ordering.
How to measure an existing ring
- Choose a round ring that fits the intended finger.
- Measure straight across its centre from inside edge to inside edge, in millimetres. Do not include the metal band.
- Compare that figure with the inside diameter column above.
How to measure your finger
A jeweller's ring sizer is preferable when accuracy matters. A narrow, non-stretch paper strip can give a rough starting point: wrap it comfortably around the finger, mark the overlap, then measure its length in millimetres. This is circumference; compare it with the circumference column, without dividing it.
Repeat at a comfortable room temperature. Allow for your knuckle and for changes in finger size during the day. Do not pull the strip tight or choose a size from a single uncertain reading.
Before choosing your size
- Measure the correct finger and hand.
- A wide band may fit differently from a narrow ring. Compare with a similar band where possible.
- Do not assume a ring can be resized: the design, stones and finish determine what is possible.
- Available sizes vary by product. The table does not indicate stock availability.

Diamond, April's birthstone, is cherished for its clarity and strength properties. In ancient traditions, wearing your birthstone was believed to bring good fortune, resilience, and amplify your natural gifts.

We recommend that you store handmade jewellery in the original box, a soft pouch, or wrapped individually in non-abrasive fabric.
Remove sterling silver and gold-plated jewellery before exercising, showering and swimming. Make sure you allow body lotions and fragrances to dry on the skin before wearing jewellery.
From time to time wash your jewellery in soapy water, using a soft brush to remove dirt. You can use a jewellery polishing cloth to restore its original shine.
