This is pretty self-explanatory! Which of the 'Big Three' coloured stones (Ruby, Emerald and Sapphire) do you prefer and in which order? Ruby, Emerald, Sapphire. Ruby, Sapphire, Emerald. Emerald, Ruby, Sapphire. Emerald, Sapphire, Ruby. Sapphire, Ruby, Emerald. Sapphire, Emerald, Ruby. I like them all, but if I had to choose, I think I like Sapphire best, followed closely by Emerald and then Ruby.
