Ink Review 

Supplies Used:

Smear Test (Dry Time):

  • 15-20 seconds – This ink has as a medium to long dry time. It shouldn't be an issue for writing in your journal! 

Drip Test (Water Resistance):

  • Low – This ink is not water resistant at all, but if you do care to dilute it you can get a wide range of green shades from it.


  • High – It's a very dark green; one of Diamines darkest greens in their traditional line of inks. With the right pen and paper you will get a nice touch of red sheen.

Ease of Cleaning:

  • Easy – It may linger on the fingers but cleaning it from a pen is a breeze. 


  • Medium/High – The ink delivers some shading where the ink pools to a very dark deep green. It will give you some great color variation but still yields a consistent line.


  • Medium – It's not one of Diamines wettest writing inks but it's certainly not dry. Flow is medium, with a slight nod toward the wet side. 

 Packaging and Aesthetics:

  • 30ml plastic, 80ml glass bottles and cartridges are available. 
  • The larger bottles are easy to fill from.

Diamine Sherwood Green is a great standard dark green that yields a lovely rich color. It's dark enough to be easily legible but still has a slight touch of shading and with the right nib and paper, you'll get a nice red sheen in certain spots. It's not water-resistant so be careful with the grocery lists or your morning cup of coffee. Besides that, it's one of Diamines best greens and would compliment any collection nicely!
