It sounds like a cymbal either played veeeery quietly with a soft mallet drumstick, or a gong that's digitally modified into a more spacious sound. Those are my guesses.

What instruments were used for Final Fantasy X OST - Wandering Flame - YouTube ?

There's definitely an organ in there, and maybe some kind of flute. But everything else is still a mystery to me. Violins maybe?
