Most gem stones will scratch glass. The hardness of glass is five and most gem minerals have a hardness between six and ten. A better question would be: Which gem stones won't scratch glass?

lots of rocks can cut mar/cut glass
to note, diamonds dont cut glass.
saws with diamond tips can cut glass but diamonds would only scratch glass if you held one and tried scraping glass.
