well i am mostly interested in what the density is and the hollow feature is natural, and not from casting or man made operations. And there seems to bee a white crystal inside the hollow feature. But again how big is the chance you find a round meteorite.
Do you have any meteorites that you have purchased? You know, some certified meteorite with an entry in the bulletin. It would be a pity if, being so enthusiastic about the subject, your life goes away and you waste it without ever having had a real meteorite in your hands. It would be a pity considering how easy it is to get an authentic meteorite these days.
The amount of time you invest in searching for the bottle cork in the ocean could be invested in learning the theoretical and academic side of meteorites. Learning under what physical and chemical processes they are formed would help you realize why your guesses are wrong from the beginning.
Take my advice:
1.- Buy your meteorites. Don't waste time looking for what doesn't exist or seeing evidence where there isn't any.
2.- Invest part of your free time to learn about planetary formation, basic astronomy, basic chemistry, basic physics
3.- Once both things come naturally to you and if you still have the interest in finding meteorites, save money and take a travel to the deserts to look for meteorites. There are people in Africa and South America (Chile) dedicated to doing meteorite search tours. I know Chilean people who are meteorite hunters. Some of them have findings classified in the Meteoritic Society bulletin.
