Having a diamond irradiated (white to pink).

I hope this is in the right section.

Has anyone ever sent out a white diamond to be color changed by irradiation?
I contacted a company called PrisimGem and they said that the coloring process is $90 per carat.

Hello, while I cannot speak from experience I suggest that you take a look at these two threads, they discuss color treated diamonds and briefly mention the company you are referring to:
