Monteverde Olivine from the Gemstone Collection is a dark olive green fountain pen ink with medium shading and a little bit of black sheen in large swabs. It dries in 30 seconds in a medium nib on Rhodia paper and has a wet flow. Monteverde inks feature ITF, which drastically improves ink-flow quality, extends cap-off time, and lubricates and protects the ink feeding systems from corrosion and clogging.

Traditionally used as a form of jewelry or other adornments, gems have always captured the eye of men and women alike. With this in mind, Monteverde USA has created the Gemstone Ink Collection, a line of brilliant fountain pen inks that are rich in color and vibrancy.
