Diamine Ink

Diamine inks have been produced since 1864, making it one of the older ink companies.

The company makes drawing inks, which should not be used in a fountain pen. It was in 1864 that the company was founded in London when the company was founded as T. Webster and Co. In 1925 the company moved to Liverpool. In was in 1964 that the company changed its name to Diamine. The ink has history and points of fame. For example, Monaco Red was formulated for Prince Rainer III of Monaco - appropriately named. Royal Blue was used by President Obama and Medvedev for the sighing of the nuclear arms treating at Prague Castle in 2010.

The ink is reasonably priced and of a high qualify. I can only remember one ink that did not work well in a Montenegro Pen. It was not only me, as at the time, other members of the Vancouver Pen Club reported the same difficulty. Havasu Turquoise is a colour to take care with as I found the ink did leave a stain on light toned celluloid.

I have been buying Diamine ink for as long as I can remember and I do so with confidence. Quality and colours are very good. There are numerous colours do you should not have a trouble finding one that is right for you.

In 2010 Diamine changed the brand naming and packaging of its ink. Gone are the Old English and New Century designations. Now it is simply Diamine Fountain Pen Ink.

The standard glass bottle is large, 80 ml of ink, which is a third bigger than what many consider a standard size of 50 ml. There are other bottles, The Anniversary Line comes in a 40 ml triangular bottle. The company also issues a 30 ml plastic bottle - kind of like a tester bottle. They also make a 50 ml line of shimmering inks in an oblong bottle. Finally, they also make a 50 ml inkvent selection. That ink I have not tired and can not make any comments.

The 80 ml Bottle

For me, this is the main line of inks. The last time I looked at their web site there were 110 colours! The bottle looks good on the desk. It is very stable and taller than wider so a good bottle design for filling a fountain pen and getting access to the ink when the level starts to go down.

Blue Moon - Diamine Ink

Blue Moon, Diamine Ink

Blue Moon

I was drawn to this colour as it was different than the typical blue. There is a dark teal tone to the ink giving the colour just that little different look. The ink is great for both business and personal writing. After I got the ink I started to see web postings that this ink was exclusive to the Philippines. Other notes about the ink referred to Blue Moon being almost the same as Diamine's Skill & Roses, an ink that was produced for German retailers. All I will say for sure is that ink does not look anything like the label on the bottle.

Performance is very good. The ink has good flow. I have used it on various papers and there is no bleeding or feathering. Likewise, I have been using the ink in various pens and performance is good across all the lines.

Jet Black

I like this colour. It has good flow and a good dark tone. This colour is not as black as some of the super blacks such as J. Herbin Perle Noire or Aurora Black, but of the blacks that Diamine produces, this one has the blackest look. There is no gray tones to the strokes.

In testing this in with various pens it is a very good performing ink.

I gave the ink a water test and I was impressed, the ink held to the paper. There was some smearing, as to be expected, but all of the ink did not just lift off the paper.

I wrote a line of text, waited five seconds, and then dipped my finger into a cup of water and ran the wet finger across the text. Not bad. I notice that others have felt that the ink takes a little too long to dry - around 10 to 12 seconds.



I was thinking of a but it is almost a very dark grey. As I wrote with this ink, the gray-black tones are you see as the ink hits the paper and when it dries.

It may be me, but I kind of see a bit of green in this ink also.

Good performance in a couple of different lines of pens. It dries within a reasonable time frame. I have been using it in OMAS and Pelikan pens with Broad nibs. No shading in terms of colour. The line of ink seems very consistent on all the strokes.

For those who want to use a gray ink, but want a little more character to the colour, then this is an option to consider.


Diamine Grey

Grey, Diamine


For this particular colour they name as it is, Grey.

2020 was the search for the perfect grey. I tried grey inks from just about all the brands. I needed something that had enough presence on the paper that it look good, yet was distinctive. Diamine Grey came out near the top. Good flow. It performs well. Good ink flow and the colour dries just a tad lighter. 

Diamine Earl Grey

Earl Grey, Diamine

I could not find Earl Grey anywhere and then on Amazon I found some 30 ml bottles. So I bough a number of them, and because the little bottles can not take the full nib section of my fountain pens, put the ink in a more versatile bottle. I like the ink, especially for business. It is a grey that leans to the black.

Earl Grey and Grey Comparison

Earl Grey, Diamine and Grey, Diamine side by side. Early Grey is closer to a black.

Earl Grey and Grey compared

In trying out the various grey inks made there is usually only a subtle difference between the colours/brands. Some are not distinctive, for example the Caran d'Ache Infinite Grey is a very light silvery colour But for the two Diamine inks, the Earl Grey tends to lean a little to the grey/black; and the Grey has its own distinctive tone.

150th Anniversary Line

The sixteen colours in the line were issued in 2014, and they are still available on the company's website as well as retail stores. The ink comes in smaller (40 ml) triangular glass bottles and sells for basically the same price as the 80 ml bottles. Unfortunately I do love a few of the colours. When eight of the bottles are placed side to side, they form an attractive circle. Still working toward my eight.

Blue Velvet, Blood Orange, Dark Forest, Regency Blue, Safari, Silver Fox, Terracotta, Carnival, Burgundy, Tropical Green, Golden Honey, Expresso, Purple Dream, Lilac Night, Tudor Blue.

Diamine Blue Velvet

Diamine, Blue Velvet

Blue Velvet

This beautiful blue is found in the 150th Anniversary Line of inks by Diamine.

Blue Velvet is a rich, dark and smooth-toned blue ink. Ever since I have started to write with it. I must say the smooth, deep toned song "Blue Velvet" instantly starts playing in my head. Good choice as this ink writes with a smooth colour tone rich and for me, addictive. I think the ink can be referred to a cornflower blue.

Very good performing ink on good paper like Rhodia, Fabriano etc. but more important, even on everyday office copy/printer paper..

Diamine Salamander

Diamine, Salamander


I love the olive-toned greens, and Salamander is one of my most used Diamine inks. I also use Safari, the colour that pointed me in the end to Salamander. A well performing ink. Smooth flow, reasonable dry time. The Salamander is a bit darker than Safari but both have the warm olive colour tone. I have used this on Rhodia, Clairefontaine and Fabriano paper all with great success. Heck, this ink even writes well on cheap office quality photocopier/printer paper. Some times it has a bit of a brown tinge to it, but overall it stays true to being a member of the green family.
