Any small stone anywhere proberly, though one stone out of context is near to not identifiable anymore as lots cross over to nature with near to no recognising.
Example = one cluster of 4, same shine, stonetype, size. One provable, one measurement with a story and one usable, and the forth looks like nothing, I know it belongs because of the other 3.

I have about 5 to 10 small stones ornament style like the large stones, that are provable by the summier modification marks that are known; square, 2 ways of flaking, crushing, sanding/rub, last shine/different grades.

I did find one small stone once long ago in Germany/Duren. But that got lost. I remember it for it's squareness and a lady like head to it. This shows the international character to a same style, though it's just a memory and can't be proven.

What can be proven is the simularities of the small stones to the large stones, and that proberly the small stones are the ornaments that people would have had in their living or pockets. The small stones are hand stones or positioning stones with a few peg exceptions.

As the site we're excavating has the stones together, alot of a picture emerges, 7 square meters over 5 years.
Clusters of the same stone type, earth colourings, etc.
