Hi David
Thanks for your enquiry.
We actually have that ring in stock, so if you knew of her finger size roughly, you could order it and we could send you a ring sizer meanwhile to get the exact measurment, and then send you a ring of the exact size she requires afterwards. As 19th is soon you would need to order by tomorrow.
Please call me if you like anymore help on the direct line 0208 457 3362
Kind Regards
Debbie Fisher
