Frequently asked questions

Ring resizing is free to all clients who have created the ring in question with JCO London, as part of our lifetime care package.

The fewer sizes the ring is resized to, the better. Typically, rings can be altered up or down by 3 ring sizes. Any more than this, and the ring would have to be entirely remade.

No, but there is a limit to how many times you should resize your ring. If possible, try to stick to less than three resizes throughout the ring’s lifetime. If a ring is resized any more than this, it is likely to become weaker and less durable to withstand life’s daily activities. If you’re looking to resize an antique ring, consult an expert to ensure the ring is sturdy enough to withstand alterations.

Resizing your ring isn’t always the best option - and in such instances adding what we call ‘speed bumps’ may do the trick. These small additions (to the inside of the band of the ring) can help to create a more comfortable fit that ensures your ring won’t twist around.
