Chopard Repair Happy Diamonds

[Bonsai]

I have 2 chopard rings with happy diamonds. I need to do a small service and am trying to get a ball park.
What's an estimate on cleaning the crystals?
Resizing?
Replacing a scratched crystal? they wont tell me anything without seeing it so I am just seeking a ballpark.

Can you send it in for an estimate? I would definitely send to Chopard and find out. Without a doubt you will be able to have them returned if it is not what you want to pay.
