So I received the “natural” sapphire. Just at first glance (I know that’s not an accurate way of seeing whether it’s natural or not BUT) there is no way this stone is natural. It’s bubble gum pink under my indoor lights.
... I'm confused - are you wondering whether it's natural because of the color indoors?
Because it's a totally normal, common, standard color that medium pink sapphires show. And the ones with more pink actually go even pinker, and hot pinks turn into rubies in yellow light. There's nothing at all strange about the color itself on my monitor.
The report, on the other hand, well. Might as well not have one if they can't even spell corundum right..
I do see what looks like abraded facet edges in the second photo though and that might be a cause for concern. Glass filled corundum shows those because of the low hardness of glass; it's uncommon in natural stones (does happen, but very rarely and to a very small degree). If it was for a very low price on top of that - a 4 carat would be in thousands even if light pink - then yes, it's probably some funny business.
