This 50ml bottle of Jacques Herbin 1670 Émeraude de Chivor (Emerald of Chivor) green-blue ink has intense red sheen and gold flecks, and was originally released in August 2015. This is the fourth ink in the Jacques Herbin 1670 Anniversary Ink series.

Jacques Herbin is said to have kept an emerald in his pocket during his voyages as a good luck charm. These precious gemstones have been treasured for centuries as protective talismans. One of the purest emerald deposits in the world, the Chivor mine was discovered in the middle of the16th century by Spanish conquistadors.

Chivor emeralds were much in demand, and the emperors and royalty of India, Turkey and Persia sought the New World treasures once the gems arrived in Europe. Emeralds were enormously popular with the Mughal Court, whose emperors referred to them as "Tears of the Moon" because of their opaque transparency.

This beautiful emerald green blue ink contains a red sheen with gold flecks throughout, enhancing your writing with an elegance and beauty that is unmatched by other inks. Each 50ml bottle is hand dipped in sealing wax with a stamped "1670" seal on the front and individually packaged in a collector edition box.

Jacques Herbin has been around since the year 1670, hence the name for their premium ink line. The 1670 line launched in 2010 at their 340th anniversary with the ink Rouge Hematite, the first in the 1670 ink series. That ink is a deep red with a gold sheen, and still sells today. They followed up with Bleu Ocean in 2012, Stormy Grey in 2014, and then Emerald of Chivor in 2015. The ink comes in a 50ml bottle with a decorative wax seal on the bottle, and a supple wax cap. The neck of the bottle is fairly narrow, so you may want to decant the ink into a sample vial, another bottle, or use an ink syringe with your big/fat nibbed pens!

It is an ink formulated for use in fountain pens, though Jacques Herbin does put a pretty scary warning on the box about it being highly saturated and how you should clean it out of your pen regularly. The gold sheen is achieved by some sort of fine pigment that is quite visible in the bottle and even in your pen (if you can see in your pen), though we've found that it the Herbin warning is probably a little overstated. You will definitely want to be diligent about maintaining your pens with Emerald of Chivor in it, though no particular caution needs to be taken as long as you're exercising regular pen maintenance.

Due to the amount of particulate in this ink used to achieve the sparking look, you may experience restricted ink flow in some of your pens. We recommend shaking the ink thoroughly before filling and gently rolling the pen in your hands often to keep the shimmer effect consistent. This will also help prevent clogging. You will also want to be diligent about cleaning and maintaining your pen when using this ink.
