The crystals pictured at the right are of basic fuchsine, also known as basic violet 14, basic red 9, pararosanaline or CI 42500.
Their structure differs from the structure shown above by the absence of the methyl group on the upper ring, otherwise they are quite similar.

They are soft, with a hardness of less than 1, about the same as or less than talc.
They possess a strong metallic lustre and a green yellow color.
They leave dark greenish streaks on paper and when these are moistened with a solvent, the strong magenta colour appears.
