Hey there, ink lovers! Madigan here, reviewing a brand new addition to the Diamine line, Diamine Oxford Blue. As an ink addict, I’m always intrigued when companies come out with new inks. Diamine has been especially innovative in the past couple of years with their line of Anniversary inks, followed up by the Shimmertastic collection. So when Diamine Oxford Blue was announced, I couldn’t wait to get my pen inked up. I instantly fell in inky love. Diamine Oxford Blue is a classy, dark, and sophisticated blue with enough saturation to make it incredibly beautiful. On top of all that goodness, it has some red sheen! Read on to discover all the ins and outs of my new favorite blue ink.

Supplies Used:

Smear Test (Dry Time):

  • Medium– This ink was dry in 20+ seconds, making it an average ink. It would be good for every day writing, but will not be ideal for lefties or for lighting fast page turning.

Drip Test (Water Resistance):

  • Low-This ink blurs quickly when water hits it. I can see it being gorgeous in ink washes, but if you are looking for your writing to stick around for awhile, look elsewhere.


  • Medium-While this is a dark hued ink, you can certainly see a difference between the first and second swabs. The second and third look the same, however.

Ease of Cleaning:

  • Easy-Since this ink has no water proof qualities and has low water resistance, it is easy to clean out of your pen!


  • Medium-While I’m generally a sucker for shading, I liked that this ink had a bit of shading, but not so much as to be distracting.


  • Medium– Fantastic flow! It flowed smoothly from the pen with no hard starts or gushes. In terms of flow, this would be a great every day writer.

Packaging and Aesthetics:

This is truly a singular ink, and is my new favorite blue! It’s somewhere in between royal blue and navy, making it a beautiful and classic hue that will go with just about anything. The saturation coupled with the slight amount of shading make it incredibly pleasing to look at. It looks fantastic on both white and cream paper. It’s work appropriate while being pretty enough to make you look forward to filling your fountain pen. It’s well behaved with great flow- perfect for long writing sessions.

You can find Diamine Oxford Blue at GouletPens.com in an 80ml bottle for $14.95 or a 2ml ink sample for $1.25.
