You can commission a ring as a gift even if you do not yet know the size. The design and the stone can be agreed first, and the size can be settled as soon as you have a reliable measurement, or after the ring has been given if the design can be resized.
This comes up often with anniversary gifts, birthday gifts, and surprises where asking directly would give the game away. A missing size should not stop you starting the conversation. It only needs to be resolved before the ring is made, or handled honestly afterwards if a resize is possible.
Start with the piece, then close the size
The part that takes time is agreeing what the ring should be: the shape of the stone, the metal, the setting, and any engraving. We work by video consultation and message, with no showroom, and we can look at stones in our diamond collection with you. Making takes 5 to 6 weeks after written approval of the CAD and the stone, with a 70 percent deposit at that point and the remaining 30 percent before dispatch. The size is part of that written approval. If you are still waiting on a measurement, you can get the design to a point you are happy with, and hold the final approval until the size is clearer.
For Christmas, the design must be complete and the 70 percent deposit paid by Thursday 19 November 2026. If that date is close and the size is still unknown, tell us as soon as you can, so we can be honest about what is still possible.
Ways to get close to the size without asking outright
Borrowing a ring they already wear on the same finger, or asking someone who knows, is often enough to get close. Our guide to finding a ring size without ruining the surprise is written with proposals in mind, and the same methods can help with a gift. You can also look at our guide to checking a UK ring size at home if they can take a measurement themselves later. A close estimate is better than a guess, but it is still an estimate. Hands change, and a gifted ring may need a small adjustment.
Giving the ring, then arranging a resize
If you would rather give the ring and settle the fit afterwards, that can work when the design can be resized. We include one free resize within 1 month, provided the design allows it. Some styles, including many full eternity bands, cannot be resized in the same way, and we will say so before making begins. If the ring does not go on easily on the day you give it, do not force it. Leave it in the box, as we suggest in our guide to what to do if a ring does not go on, and come back to the fit when you are both at home.
If you would like help planning the gift
If you are choosing a gift for an anniversary, our guides to first wedding anniversary gift ideas and to anniversary gifts by year may help with the occasion, even if the size is still open. For a gift that is a stone rather than a finished ring, we also have a short guide to buying an unmounted diamond as a gift. Get in touch when you are ready, and we will talk through timing, design and what we can do about size.
Frequently asked questions
How can you commission a ring as a gift if you do not know the size?
You can still commission the design and the stone, then settle the size as soon as you have a reliable measurement, or after the ring has been given if the design can be resized. A careful estimate is useful, but it should not delay the conversation about the piece itself.
Can you give the ring in its box and have it resized later?
Yes, if the design can be resized. We include one free resize within 1 month, provided the design allows it. Some styles, including many full eternity bands, cannot be resized in the same way, which we will discuss before making begins.
Is it better to wait until you know the size before you approve the design?
You can approve the look of the CAD and the stone, and hold the final size until you are more sure. Nothing is made until the design and the stone are approved in writing, along with the size we will make.
How can you estimate a size without spoiling the surprise?
Borrowing a ring they already wear on the same finger, or asking a family member who knows, is often enough to get close. Our guide to finding a ring size without ruining the surprise is written with proposals in mind, and the same methods can help with a gift.
