✅ SOLVED Strange rock in sphere shape

[Fodegrass]

It is a sphere rock except for that small part in the left side of the image. It is also heavy compared to its size and it is non magnetic.

Not a lot to go on here.
Some background info on where and how you found it might help.

My first thought, was that it's a Whopper!

I found it in a lake in madurai tamilnadu india

Could be a large worn almandine garnet. That would be heavy and non magnetic.

So it's a petrified whopper?

I would lean toward lead fishing weight. Found in a lake, non magnetic, heavy for it's size, and appears to have a loop.

It has a dull surface completely without any Lustre, is it possible for almandine garnets to be like this?

A friend of mine told me it is usually found in red soil but he doesn't know anything about it.

Yes, they can be very rough and crude.

It looks like to me as Moqui Marbles, as I have several in my mineral collection. Here is a bit of info about them. https://rockseeker.com/moqui-marbles/

Strictly speaking, 'Moqui Marble' is a colloquial name that applies only to concretions from the Navajo Sandstone of America (principally in Utah).

That doesn't mean it's not a similar concretion from elsewhere. They're composed of a mixture of the oxides hematite and goethite and there should be enough hematite to give a distinctive red or reddish brown streak on the back (unglazed) side of a porcelain tile.
