hi my name isXXXXX can help you
you will need a pair of small pliars to remove the spray arm, and a phillips and a number 15 an 20 torx to remove the cover off the pump
using the pliers you rotate the spray arm support counter clockwise and the spray arm once loose comes right off the support
to pull the cover off the pump you take out the torx screws that hold the cover in place, not sure were your jewelry is but if you can see it thats probably as far as you need to go
hope this helps if you need further assistance le me know otherwise don't forget to press the accept button and leave a comment, thank you, Tim.
I was able to remove the spray arm but could not remove the cover. Since then we purchased a fexible grabber which enabled us to retrieve the pearl. Thank you Frances Lynch
