Ink Review #807: Diamine Graphite


I’m on a grey ink kick this week, and the last two I reviewed are way too light for my tastes, so let’s take a look at a darker grey, Diamine Graphite. I purchased my bottle of ink from Cult Pens.


The color:

Graphite is a medium grey that can appear much darker in a wet nib. It has a slight green undertone to it.



In large swabs the green undertone is easier to see, as well as some of the black 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: 40 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: None

Other properties: low shading, low sheen, and no shimmer. The sheen was only visible in large swabs and flex nibs on Tomoe River paper.

On Staples 24 lb copy paper the ink feathered and bled in all nib sizes.

Comparison Swabs:


Diamine Graphite is lighter than Robert Oster Graphite but darker than Lamy Agate. Lamy Agate has a green undertone, similar to Diamine Graphite’s. Click here to see the Diamine inks together, and click here to see the grey inks together.

Longer Writing:


I used a Visconti Homo Sapiens Bronze Age with a medium nib on Tomoe River paper. The ink had an average flow. Because this pen has a wetter nib, the ink appears much darker than it is in the other writing samples.

Overall, it’s not my favorite grey ink, mainly due to the green undertone, but it is a good solid performer.
