many pressed glass surfaces appear shiny and polished, and was this ability to mimic cut glass that brought into being much of the trade in pressed glass in the middle of the C19 - although the sharp 'edges' of true cut glass probably always defeated the makers of moulded work.
The sharp edges of cut glass were lost after the 1920's as a result of acid polishing which was a more economical and rapid method of removing grinding marks. Run your fingers over a piece of mid C20 cut glass and the smoothness is very apparent, usually.
The intersection of two flat surfaces - form an arris - or edge as you say, and on older glass these raised features are vulnerable to damage although far less so the newer the piece.
If you can get alight source to provide a raking effect on the sides, and get your eyes really close (or use a loupe) you should be able to assess whether this is pressed or cut.
If cut, then you should see, albeit faintly, the shadowy remains of grinding marks - the merest hint of lines running at ninety degrees to the axis of the obelisk - if pressed then no matter how close you look you will never find even a hint of these lines.
If the inclusions are mica, then under a decent light individually they should give a hint of sparkle, especially as mica flecks usually show flat planes - according to Wiki the word mica is derived from the Latin word, mica, meaning a crumb, and probably influenced by micare, to glitter.
If the inclusions are a dull white, then not really sure what they'd be - sorry.
Now off for more chocolates, beer and tv. merry Christmas all.
