Ink Review #778: Diamine Steel Blue


I love teal inks, especially in the summer so I checked for teal inks I haven’t reviewed in my ink drawer and came up with Diamine Steel Blue. It’s a gorgeous bright teal. I purchased my bottle of ink from Cult Pens.


The color:

Steel Blue is a bright, medium teal.



In large swabs the ink has a little bit of 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.

Longer Writing:


I used a Pelikan M600 Turquoise with a broad nib on Tomoe River paper. The ink had an average flow. I really like this pen/ink combo.

Overall, I really like this ink. Diamine does a great job with teal inks, and this one is another winner.
