Hi Jane,
We can make the ring for you in yellow gold, no problems, it would be the same price and would take 4 - 6 weeks to complete.
A couple of things though...as we would be making the ring for you it would become non refundable, it's still covered by our 5 year guarantee etc, it's just non refundable.
You also need to be sure of your finger size as it's a ring that once it's made needs to stay that size.
If you would like to chat this through please do call us on 0845 084 1200 and we would happily answer any questions you have.
