Does a perfect appearance mean a better walnut?

The central idea

Unusually round or uniform forms can merit further questions about treatment and source. They are neither automatic evidence of quality nor proof of intervention. Check the shell, surface and natural transitions, then consider appearance as part of personal preference after the foundations are established. This opinion piece questions a market in which regular, enlarged or artificially altered forms can make natural growth seem undesirable. It asks collectors to return to source, risks, shell quality and surface condition. Natural variation needs understanding, but it does not excuse structural damage or an unverified pair.
