Help with Stone Check - Lab OMC Cushion (4.03 F VS1)

[idaman]

Hi, I’m not exactly sure what to look for so I was hoping someone could help point me in the right direction. In person under bright lights it produces big bright flashes. Does it look normal for these dimensions? Does this look good, or can I do better? Price is $5073 USD.
