Ink Review #775: Diamine Aurora Borealis


Diamine Aurora Borealis is the second ink created for Reddit’s r/fountainpens. I really like the first one, Diamine Earl Grey, so I decided to give this one a try too. You can find this ink at Pen Chalet.


The color:

Aurora Borealis is a beautiful dark teal.



In large swabs the ink has some pretty red sheen.


Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 30 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: Low-there was just a little bit of bleeding on Rhodia.

Other properties: medium shading, low sheen, and no shimmer.

On Staples 24 lb copy paper the ink feathered in all nib sizes and had a little bit of bleeding.

Comparison Swabs:


Aurora Borealis is closest to Robert Oster Deep Sea. Click here to see the Diamine inks together, and click here to see the teal inks together.

Longer Writing:


I used a Lamy Safari Petrol with a medium nib on Tomoe River paper. The ink had an average flow. I really like this pen/ink combo.

Overall, I really like this ink. I have a weakness for teal inks, and this is a good one. Robert Oster Deep Sea is very similar to Aurora Borealis, but Deep Sea has just a little bit more sheen.
