My thanks to Danny for the ink sample.
Montblanc Emerald is Montblanc’s 2018 Colour of the year. It is a delightful colour. The green is bright and it pops right off the page. It shades well, going from a dark saturated green to a bright blue-green colour. But with the price of Montblanc non-standard inks going up, I’m not sure I’ll add it to my collection even though I really enjoyed this ink.
