Now, one of my favorite qualities of this ink is the shading. If you look at an amethyst gem, you don't see a single shade of the color. You see several different shades since there are different angles, thicknesses, and gem qualities. The Amethyst ink captures these qualities beautifully. The shading properties aren't incredibly dramatic, but they're beautiful and striking without being flamboyant. This is an ink that does extremely well in a broad or flat nibbed pen (like a stub or italic).
This is an elegant ink with some great surprises in store. People definitely notice the character.
Color
The color of the ink is very similar to the gem. Pelikan did a fantastic job matching the color. In use, it's a medium purple. If you're using it in a smaller nib, it looks entirely professional for most things. In a wider nib, it exhibits a nice range of light to medium dark purples. In any nib, it looks great and shows its character well.
