Gmail – How to move Google contacts between two different accounts

There is no such thing yet, but in order to speed up the process you can do the following.

For example if you have 5 e-mails for one contact.

1. Add 5 new empty e-mail fields
2. Click on the first e-mail and then press Ctrl+A to select all and Ctrl+X to cut the selection
3. Click on the first empty field and Ctrl+V to paste
4. Continue with the rest
5. Don't delete the empty fields, they will be removed automatically once you hit the save button

(If you are on a mac use Cmd instead of Ctrl)

It appears that Google Contacts is one of the services which does not have a sharing option, but does have a data transfer option.

Transferring data between two Google accounts would involve exporting and importing.

Update: One alternative would be to set up a Google Apps account and use one of the workarounds to share contact information.
