Hardness : it barely scratches glass, can't scratch gorilla glass of my lg g2
Transparency : translucent, you can see the flashlight of a smart phone.
Luster : it has glassy luster. Shiny surfaces.
Density : it is light like a piece of aluminum or even lighter a bit.
Streak : it has white streak. Smells like a matchhead when I slide it through a surface of quartz.
