Diamine Blue Black Ink Review

Diamine Blue Black Ink Review

It's been quite a while since I've had the inclination to reach for a blue black ink for one of my fountain pens, but I've had a resurgence of interest lately and have decided to go with it. The first ink on my list of blue blacks is from Diamine. This is the standard variant, not the special 1864 150th-anniversary or registrar's versions.

Diamine Blue Black is something that I consider to be a very solid blue black ink by definition. The color is dark but still obviously blue, there's a nice level of shading, and there aren't any purple undertones present. With any blue black, the color is important and often a point of intense opinions. I'm not a fan of blue blacks that are so black that you can barely see any blue, but I'm also not a fan of washed-out, light blue black variations that look more like a watered down black. Diamine's interpretation of blue black makes my heart happy. It's a dark navy with plenty of inky mystery, but it also lets the lighter side show through on lighter strokes. It strikes the crucial balance of darkness and blue that meets my individual expectations.

Diamine Blue Black Ink

Like all the other Diamine inks I've tried, this one is very well-behaved. I haven't noticed any feathering or bleeding, regardless of the paper I use. It's a dark ink, so there's a fair amount of show-through on the back side of the page I write on, but it's not too bad and it's easy to ignore if I'm using a nib that's under the bold size.

One thing that I did not expect about this ink is how wet it is. Especially in the 1.1mm stub nib I used for this review, the ink just flows out of the nib with ease. It doesn't seem to affect the line crispness, but it certainly increases the dry time. In my tests (in the very humid southeast US), it takes anywhere between 20 to 30 seconds for this ink to fully dry on Rhodia paper. It's a little quicker on uncoated paper, but not by much. If you want a quick-drying ink, look elsewhere!

Several other blue black inks I've tried in the past have a significant sheen that you can see in certain lights. I haven't noticed any sheen in Diamine's version. If you want an ink with a lot of fancy sheen, you should also look elsewhere.

Even though this ink is wet and doesn't have any sheen, I can't help but love the subtle amount of shading it presents. This looks particularly great in a large nib because you see a variance of dark, dark blue and medium blue as you write. What I really appreciate is that I can't see any hint of green, purple, or gray in the lighter shades of this ink. That's something I've noticed in other blue black inks that I don't like. Again, this is what makes Diamine's blue black a true standard for my book of inks.

Diamine Blue Black Ink Swab

And as you might expect with Diamine, it's also a great value. The 30ml bottle I picked up is less than $8, and the whopping 80ml bottle is less than $17. If cartridges are your thing, then an 18 pack of cartridges is only $8.25. If you only want to try this ink out first, I think the smaller 30ml bottle is a good choice.

Aside from the really long dry time, this ink is a stellar performer. It nails the definition of a solid blue black ink for me, and I'm looking forward to using it more in the future as I rotate more dark inks into my pen usage.
