Gemstone Ink Collection Traditionally used as a form of jewelry or other adornments, gems have captured the eye of men and women alike, expressing through their beauty what our words cannot. 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. Each ink will add a layer of expression and value to your handwriting. Included in this gift box is a representation of the Gesmstone Collection, our top 10 favorite colors: Sapphire, Olivine, Topaz, Fireopal, Amethyst, Charoite, Erinite, Ruby, Garnet, and Onyx. Each ink is made with Monteverde USA’s European ink treatment formula (ITF), which drastically improves ink-flow quality, extends cap-off time, and lubricates and protects the ink feeding systems from corrosion or clogging.
