Hi. There are many options that you can choose when greeting your PSAs, CSAs or new Designated Diamonds. For example, if you really don't have any idea about what to say to your new designated diamond, I suggest you to use other tools like e-card. You can directly mail your preferred e-card to your new designated diamond and simply type down something like "congratulations! and wish we can co-operate successfully", or "Welcome, and wish you have a bright future here."
