Diamond Color Code to represent earring in a pixel art

[sarahnicolls]

What color code as an artist would you recommend to represent a diamond earring (20*20) on a pixelated art? Only one color is allowed.

Thanks

Do you have a working example? Most diamonds are not a single color, their colors are reflections, refraction's, and prismatic.

Art??

Thanks @IamSam
something like this with a diamond earring in one of his ear.

As this would be so small, I think white or light pale blue should do the trick.
