Looking for around 1 carat, H-SI1 or higher with excellent cut.
The proportions on this diamond seem pretty good to me. Hard to tell if this is eye clean or milky.

This one looks cloudy.
I had a hard time finding a diamond with your specs, at that price, that was eye-clean. The option below is the closest I saw.
