The nature of the stone and portions of its history are observable facts a skilled observer may use to direct the conclusion, often using Occam's Razor. However Occam's Razor may not be flung at the stone like a blanket to describe it's history.

Now a number, but limited number, of other natural process could create the stone. But it is not random it is wholly dependent on the nature of the stone and the environments through which it traveled.

shore as in the final portion of the above purely geological scenario.
Now which is a simpler process.

Or She Who Nets Fish could find a stone that she knows she can work with another stone she knows is harder. Drills a hole, slides it a cord of a fish net which is used for years until it wears out or breaks or most likely is lost with a break in the net or in a storm and the stone roles along the

and that the water course empties into a waterbody with the proper wave energy and accompanying particles to erode and polish the stone but gentle enough to avoid destroying the fragile wings surrounding the boring until it is found on the beach by our friend in the original post.

which cracks the local rock, or a magma intrusion near by who's heat cracks the matrix and that the rock containing the boring falls into a water course large enough to carry it during flood and with co-occurring particles of the proper size and hardness to slowly and smoothly erode that rock

from the liquid flow and swirled into the bedrock drilling out a hole and than the area of bedrock containing the boring was separated from the matrix by say, the presence of pre-existing cracks expanded by frost and than seasonally freezing and thawing water wedges, or through a tectonic process

be able to date the time of the stones exposure (release from parent rock) and be able to identify the likely location it was excised from. Now if the rock was from a glaciated region and experience a high energy outwash flow over bedrock which occurred in a shallow basin where a stone was dropped

gathering and solve daily survival problems while 99% of people walking around today, including working stone. To apply Occam's Razor you would first need to know the type of stone, understand it's most likely cleavage planes, be confident of the erosive environments it was exposed to,

Here in the Upper Great Lakes that would most likely be an eroded fishing net weight. Pre-industrial people were highly intelligent. Any individual from a few thousand years ago, although they would be baffled by trying to predict stock fluctuations, would be much more likely to be able to solve

I guess I need to increase my screen time. I just missed my Tea Time.
