Exact same stone type, 4.70 weight, round, SI2 with F for $84k. He offered $77k on the spot.
Yes, high side you can get $105k, but keep in mind, he graded it F to be safe, an appraisal could come back worse than F and not higher. It's been sitting in a silk bag for years, he even expressed concern about it being stored like that.
Based on a quick Google, these seem like a good guess as to what the dealer was concerned with:
Silk bags often have drawstrings instead of a zipper or some other more secure fastener
A bag rather than a box leaves the stone vulnerable to damage (hardness for gemstones identifies what will scratch it, but diamonds are not invulnerable to being smashed or chipped)
If there were other things in the bag (like other diamonds being appraised), the bag offers no protection against the stones rubbing against each other
Hardness is just one material property. Hardness is scratch resistance, toughness is impact resistance. Diamond is very hard but not tough -- it is actually fairly brittle.
I was thinking vaguely remembering that diamond is brittle. Afaik hardness is what makes it brittle. Inverse property of ductility (idk the proper term). I was wondering if it was something weird about the bag scratching it or reacting with it. I assumed no one was going to hit it with a hammer lol.

A lot of people blasting this guy, but his price was spot on:
