Hi Ben,/p>
The smallest size I have of this ring at the moment is a size L and we are unable to adjust it any smaller.
To get this ring for you in a size J will take around 6 weeks I am afraid, you can of course buy the size L to make sure it's a ring she likes and then if she gives it the thumbs up we can then make the ring for you in the size you require and swap it over.
