Diamine Steel Blue Ink Bottle

Diamine Steel Blue Ink Review & Giveaway!

Diamine Steel Blue ink is a turquoise blue ink from Diamine ink Company based in the UK. Diamine Inks, first made in 1864, offer a wide variety of inks, colors, and options such as the very popular Diamine shimmering inks. Diamine inks are known for simple bottles with tons of colors. Their inks have great flow and are inexpensive.

Diamine Steel Blue ink is a nice blue green turquoise color ink. It is definitely not blue enough to be a true turquoise, like Lamy Turquoise, but is more of a light teal ink. The color is similar to Kobe #48 Marche Blue ink and a little lighter than Pelikan Edelstein Aquamarine ink.

Diamine Steel Blue Ink Review

Diamine Steel Blue Ink Review

During our review we found the following traits when testing Diamine Steel Blue ink that you may find useful:

Testing Factors

For this review of Diamine Steel Blue ink we used a glass dip pen manufactured by French Company, J. Herbin on Rhodia dot pad paper. The glass dip pen is equivalent to a fine tip fountain pen nib.

Bottle Sizes

Diamine Steel Blue ink comes in a large regular sized 80 ml. glass bottle as well as a smaller sample size plastic 30ml bottle. The distinctive glass 80ml bottle allows for the user to obtain those last few drops of ink. Another great option though is Diamine’s “sample” sized bottle option, which is a smaller 30 ml. clear plastic bottle. This smaller bottle allows the consumer to purchase a less expensive bottle of ink so they may try it without committing to a larger bottle. The smaller bottles are very popular and are able to travel quite well due to being made of plastic.


Diamine ink is a great value for this historic UK imported ink. The large 80 ml. glass bottle retails for $15.00, which is well in line with most large capacity economy inks of this size. The smaller 30 ml. plastic bottle retails for only $7.00 per bottle.

Dry Time

We found a quick dry time of approximately 5 seconds while testing Diamine Steel Blue ink. This makes Diamine Steel Blue ink viable as an everyday all purpose ink.

Bleed Through

During our review of Diamine Steel Blue ink we found absolutely no bleeding on Rhodia dot pad paper. Even during the cotton swab test, we found no bleeding through on Rhodia paper.


During normal use, we found no feathering with Diamine Steel Blue ink. During the water test we did see some feathering, but only at the wettest part of the water test.

Water Test

During our water test, where we run a wet cotton swab over a dried ink sample of Diamine Steel Blue ink, it created some feathering and significant color smearing. However, although they were smeared with color, the lines for the most part remained very clear and distinct. Our tests confirmed that Diamine Steel Blue ink is not a waterproof fountain pen ink.


Diamine Steel Blue ink will produce some nice shading with a light and dark shade mix while using this fantastic teal/blue-green color.

Conclusion about the Diamine Steel Blue Ink

Diamine Steel Blue ink is a nice unique blue color. It has great characteristics such as quick drying with no bleeding or feathering and is fairly inexpensive. The color of the ink is dark enough to use at home or office, but is unique enough to use for letter, note and journal taking for those that love unique coloring. Diamine Ink company produces many unique colors and have been a dependable staple in the ink community for more than 150 years. Happy writing.

While this ink color seems interesting, it’s really close to Diamond Marine… not entirely sure why Diamine made it.

Thanks for another awesome giveaway!

It’s a beautiful blue/green color. Diamine always has such great colors and quality. I’ve loved the other colors I’ve gotten from them—most recently Earl Grey.

The majority of my High School years and the decade or so following I used Skrip Peacock Blue. I still love turquoise and have at least five different turquoise inks. An example by Diamine would be most appreciated, and I might just buy it later in the year.

I’ve only recently started following reviews, so if you haven’t already reviewed De Atramentis Mint Turquoise, I would love to take turquoise even more to the green side.

What a gorgeous color! I love blue inks; all shades! I*ve been using Lamy blue in my Lamy Vista EF for every day use. I suppose some might find it boring, but I used blue ink in my fountain pens when I was in high school, so I guess it is the comfort of something familiar that I enjoyed I find attractive, now. Keep up the good work. Pen Chalet is my favorite online store. I am hoping to get to your store at some point this year! HAPPY NEW YEAR!!

I have a sample of Steel Blue ink but haven’t tried it yet. Perhaps that needs to change; a full bottle would be nice to have. Would you please review sets of colors: blues, blacks, reds, etc.?

I love Diamine and I’ve only tried their brown shades like Ancient Copper. This Steel Blue would certainly be a good everyday drawing ink. I have a use for non waterproof ink.

How “wet” is this ink? I have a KWZ ink that I love because it flows so nicely, but the dry time is ridiculous!
