Seamed: A seamed edge (not shown) has been sanded and it may be rough, but it will not be sharp. It is the most economical edge but it's not recommended if the edges will be exposed.

Polished: There are two types of polish - flat and pencil. A flat polish is
generally used on thicker glass and tempered glass. A pencil polish is often
available on glass up to 3/8" thick and some stock sizes. A polished edge is
smooth and shiny. It is relatively economical and is suitable for most
applications where the edge will be visible.

Bevel: Beveling creates a decorative angle starting near the edge of the
glass. The actual edge will usually have a pencil polish. Beveled edges are
very economical on stock sizes, however, pricing becomes higher for custom
cut sizes and is especially expensive on curves.

Other Edges: There are other edges available such as ogee, triple pencil polish (waterfall), wave, or chipped. Sometimes these edges are available on stock items but they normally have to be custom fabricated and are therefore very expensive.
