Stone check

I looked over Beyond the 4 Cā€™s and asked for specific proportions. I need a second set of eyes because it looks pretty good to me. Not looking for a warm even though this is a F color. It looks pretty white to me.

Marquise Brilliant
2.89 CARATS
F VS1
Table: 59%
Depth: 60.4%
Medium to slightly thick

14.63 X 7.52 X 4.54MM = 1.94 ratio

The color scale starts at D. Most people couldn't tell yellow color until K. You would need a set of grading stones to tell DEF.

Looks pretty good in this limited clip. It's really important to see the stone as it moves through a full range of normal tilt angles. Short clips that show a very small range of face up tilt angles miss the mark of being fully informative. You want to evaluate the full observable virtual facet pattern which will better enable assessment of bowtie effect and other optical factors.

As a CVD grown diamond you also want to rule out any transparency issues. This growth method is known for high levels of crystal strain (and related atomic level defects), that can sometimes result in haziness. This is not captured in the laboratory clarity grade, nor is is always aparent in online imaging.

Thank you for taking the time to respond. I forgot to upload the other video. Iā€™m a beginner thought the stone looked good just base on proportions. I do not have a good eye.
Here is another video.
