At what point does a red/pink sapphire become a ruby? I am curious because I have seen stones listed as ruby that looked identical to one listed as sapphire elsewhere, and vice versa. Can someone with expertise explain the criteria for a stone to be officially designated/ certified as a a ruby? I am not currently looking for a ruby- just curious and in need of education.
