Ink Review #765: Lamy Obsidian


Today’s ink is Lamy Obsidian from the Crystal collection. This color is a bit unique, it’s not quite black, almost a dark dark green. Pen Chalet has some in stock.


The color:

Obsidian is a dark black with a heavy green undertone.



In large swabs you can see 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: 20 seconds

Water resistance: Low

Feathering: None

Show through: Medium

Bleeding: Low-just a little bit on Leuchtturm.

Other properties: low shading, high sheen, and no shimmer. The sheen is subtle because it’s black on black, but it’s there. You can see it in all nib sizes on Tomoe River paper, and in the flex nib on Leuchtturm and Rhodia.

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

Comparison Swabs:


Obsidian seems the closest to Colorverse Sunspot, but it has a stronger green undertone instead of Sunspot’s purple undertone. Click here to see the Lamy inks together, and click here to see the black inks together.

Longer Writing:


I used a Lamy Safari Petrol with a medium nib on Tomoe River paper. The ink had a thick, sticky flow, it reminds me of the flow of Organics Studio’s monster sheening inks like Walden and Nitrogen.

Overall, the color is unique, and you can see a bit of the green undertone in writing. The flow was a bit sticky feeling for me, and it is a bit hard to clean out of pens. I don’t love it. It’s interesting but not one I would reach for often.
