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. Whether its adoration, excitement, longing, or honesty, show those closest to you that you care with one of our 11 unique colors: Sapphire, Olivine, Topaz, Fireopal, Moonstone, 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.

Monteverde ink has always been widely recognized as wonderful fountain pen ink, utilizing its trademarked ITF technology (ink treatment formula), which improves ink flow, lubricates the fountain pen feeding system, improves ink dry time and allows for extended cap-off time while using your fountain pen. A great selection of colors is available. Now offered in a new smaller 30 ml. glass bottle, which retails for $8.00, allowing for an inexpensive “trial” of one of these new fountain pen ink colors. Monteverde continues their ink revolutions by also introducing two permanent or “document” inks in blue and black, which allows for those who need a permanent ink for use in their business, work or other purposes.
