Ready-to-Ship rings can be resized approximately 3 sizes larger or 3 sizes smaller please allow 7-10 working days.
If you require a different size these can be made through our bespoke service please use the Contact form below.
Although many of our rings can be resized, some of our designs are more challenging than others. These include rings with shoulder stones, channel set diamonds and rings which are patterned all the way around. If you are unsure or have any questions about resizing, please speak to our design team.
Each ring is marked with the 'Jessica' logo, so you know it's authentic and ours.
Would you like to add a personal engraving on the inside of your ring?
Please type exactly what you want in the Engraving box (up to a maximum of 30 characters including spaces). Please, be careful to type in Capitals or Lowercase characters exactly as you wish the engraving to appear on the ring.
The laser engraving on the inside of your ring adds about 1 week to the delivery time.
You could write a special message, nicknames, the date of your wedding or your initials for example. We engraved our rings with a nice, clean, simple font such as Helvetica.
In addition to your engraving, all of our rings are hallmarked to ensure the precious metal used is of the fineness stated in each listing. Our hallmarking guide can be found here.
