Found it while digging the ground. This stone is very heavy, I checked if it was gold, it turned out not (I checked it with a magnet, it doesn’t magnet. What could it be? It doesn’t look like a simple stone.
I urge you to take your rock to a recognized institution that identifies meteorites. Doing so will get you a professional opinion. An Internet search should help you find one nearby.
If it's non-magnetic then, for a meteorite, it would need to be an achondrite, or a very low metal chondrite. I see nothing that resembles chondrules, so the latter is really unlikely. Neither type of meteorite is renowned for being 'very heavy for its size'... at least not beyond the density of ordinary earth rocks such as basalts.
