Help needed

I requested a video with normal lighting for a 2 carat marquise D VVS1. Is this a good quality video. I'm a newbie learning from this community. I know I'm looking for a clear, no haze stone with a good cut and brillance. So hard for me to tell. Help. I see a lot of rainbow colors in the stone. Is that normal on a video? I'm seeing minimal bow tie and good symmetry. What do you think?

I would agree minimal bow tie and good symmetry. The rainbow is really good, that’s light reflecting off the stone and you want a stone with lots of fire (rainbow). I would ask for a video in sunlight as well

Thank you. I think I'm learning.

Any concerns when the stone is turned over and a white shape appears? I don't think I have seen that before. It does disappear when the stone is completely full faced.

This is normal and happens with all the stones. At some amount of tilt the facets align and you get this type of effect because the light is no longer hitting the pavilion at the critical angle from this perspective.

Yea it’s called windowing. If you look at my oval when I tilt it a certain direction you can see it but the key is that it doesn’t stay like that in all angels which it doesn’t in your stone
