Mi Note 3 broken screen

[Sebassth]

Hi. I've a blue Xiaomi MI Note 3. The screen is broken and need to be changed. I'd like to know if there is an original screen for the phone because the replacement I saw once, had a different kind of blue (not original blue) and also no curved edges. It was a crappy replacement.
Also if someone knows where to buy on internet.
Thanks very much
