Dear chakster, We all can see what we call ''styli shapes'' but
can one see the difference between, say, Van den Hul shape and
Shibata shape? Both got patents for their design. This means that
they are different otherwise patent would be not granted. What we
call ''shapes'' the diamond industrie calls ''facets'' . The more facets
the more expensive (jewel) diamond the color included.
So only some diamond grinder or polisher can explain how those
''one piece diamond styli combo's'' can be made. We have very
similar ''picture'' about MC generators. Those looks like our Eastern
eggs which you in Russia also know. The ordinary eggs look
like twins but painted kinds look all different (grin). Faberge kinds
are the most exclusive and only meant for the kings and the very
rich.
