Diamine Blues


Aqua Blue

Aqua Blue

Aqua Blue is very similar to Turquoise but with a little more blue tones.

I have found this colour looks good at work when I was signing a letter or document, but on some days when I looked back at a full page of writing with this ink, I thought it was a bit bright for my liking. When I have used the ink for personal notes, where there is less text, it is a great colour. So it is really a matter of personal peference for this ink.

Performance is good. I have used it in various pens and the flow and dry time seems very reasonable. Depending on the pressure with which you write, and the amount of ink that hits the paper, the ink was dry within five seconds. I only found some smearing after five second where with my broad nibs there are very heavy strokes and especially in the area at the end of the stroke where the pen rested on the paper there was additional ink on the paper. To me, this is one of the aspects with writing with a broad nib and not something fo which that I would downgrade the usability of this ink.

Asa Blue


Asa Blue


I loaded my pen with the rich Asa Blue ink, and as soon as the first letters were being formed on the paper I knew this one was going to very popular. I am really enjoying using this colour.

Rich blue, some see teal in it, however, it is a good bright blue in my books.

Performance has been very good. I have tried it in various pens and the flow is good, the drying time very reasonable.

There is no significant shading. I saw that as I have used it with pens fitted with both Stub and Italic nibs so there would have been lots of opportunity for shading to take place. The sample that I have added to this page is written with a Broad nib in the Montegrappa Espressione pen. That is a big nib, and it places a fair amount of ink on the paper. Good performance.

Asa BlueThe colour sample on the Diamine website is a good representation of the colour of this ink.

All I can say is get yourself a bottle of this ink and enjoy!

Blue Black

Blue Black

I really enjoy using this colour.

I found that business writing looks very strong and easy to read because of the depth of colour. It is dark and photocopies very clearly - always a good consideration for letters etc. that you are signing at work.

The deep blue-black colour has an interesting undertone of gray-blue and this gives the ink a very interesting tone or shading. The colour is a bit similar to Noodler's Navy, but that colour has its own unique look.

Diamine Ink - Blue-Black

Good flow in some pens, and a rich dark saturation. It would call this a wet ink, and it does take more than 5 seconds to dry on paper.

The ink is made for business writing. I have received notes, however, where the ink was found to be a poor performer. Some have written me asking about feathering. I have not found that to be an issue, but it may be the type of paper that I use.

Color swatch from the Diamine website is a good representation of the colour of the ink.


China Blue

Diamine Ink - China BlueChina Blue - the colour swatch on the Diamine web site shows this colour of ink to be a very light blue. But, when when I loaded up one of my pens with this ink, it had far more punch than the colour swatch.




Diamine Ink - China BlueI liked the crisp blue look and the ink has enough colour saturation for my liking. Now over time, this is one of the inks that I come back to a few times.


Diamine China BlueColour swatch from Diamine website is not a good representation of the colour. Usually broad nibs can make colours look lighter, but all my writing seems to come out much darker than the colour sample shown.


Florida Blue

Florida Blue - Diamine InkFlorida Blue - is what I would call a good middle range blue.

Of the various blues produced by Diamine, this is not one of the colours that that I have used a lot. I tend to lean towards bolder more saturated colours and this blue would be more for those who like a lighter tone of blue.

On the times that I have used the ink, the performance was good. It has a reasonable dry time and it worked well in various pens I used.

Florida Blue - Diamine InkColour swatch from Diamine website is a good representation of the colour of the ink, although my writing always seemed to be coming out lighter in colour density.


Havasu Turquoise

Havasu Turquoise

This is a very appealing colour, a rich blue with some green to go it a turquoise tone. The blue in this colour gives it a richer tone than the Turquoise colour that Diamine also produces.

There is a distinctive look to this ink. The color swatch on this Diamine site is not a good representation of this ink.

I like the colour of this ink, but must put a warning about the staining of this ink on celluloid pens. This ink left ink stains on the outer body of one of my celluloid pens after a very short use. So I have stopped using it in that type of pen.

I was surprised at how quickly the ink stained the celluloid. Simply ink, after a fill-up, was in the cap section, when I posted the cap section on the body of the pen, where, an hour or so later was the staining.

The colour is good and I am limiting its use to my all metal pens or resin pens.

Havasu TurquoiseThe colour swatch from Diamine website is not a good representation of the colour as it has too much blue compared to the actual colour of the ink.

WES Imperial Blue

Imperial Blue


If you looked at the colour swatch from Diamine web site you would think of this as a blue ink.

When you look at the ink, and write with it, it has a very definite purple/violet colour tone.

But, despite the variance between the colour of the ink and the web site colour swatch, it is a very bold, bright, solid ink. When I go back and look at notes I took at meetings it the colour looks fine once I get over the fact that this is not a blue ink. I now refer to this ink as a bridge colour, one that bridges between blue and purple.

WES Imperial Blue - by Diamine InksPerformance of the ink is good. I have used it in various pens and have not encountered any problems.

WES Imperial BlueThe colour swatch from Diamine website, shown to the left, is not a good representation of the colour of the ink as it shows the ink as having much more of a blue tone.

Indigo Blue

Diamine Ink - Indigo Blue

Indigo Blue is one of the blues by Diamine that I must admit I do not use that much. After trying it out for a few days I found it to be too washed out. It looks like a faded blue-black. The broader the nib you use, the wide and weaker the strokes are in terms of color concentration.

Indigo Blue by Diamine InkIn terms of performance, it has good flow. Dries to a nice flat, non-shinny or sticky finish. After about five seconds the ink is dry on the paper. Colour swatch from Diamine Web Site:


Majestic Blue

Majestic Blue

Majestic BlueWhen I first tried this ink I thought I had found the ink I was always looking for in terms of the perfect blue. The ink had a very good rich blue, with just enough black to give it character but not be a anything in the black tones.

I like it so much that I order six bottles of the ink. But, as I used the ink more and more I found there were significant performance issues. So my conclusions on this ink are not based on a single bottle. I have used ink from various bottles, and still use the ink, but with caution.

From my experience, the ink does not work well in some pens, namely Montegrappa and OMAS. I have talked with others who also say they have a similar experience. I have written Diamine Ink about this problem but I never received a response back to address the question. There is something about the chemistry of this colour.

The other issue I find with this particular ink is the time it takes to dry.

Majestic BlueThis colour takes considerably longer time to dry and even after that, there is a raised feel to the ink. There is a stickiness. I have hard from others who have commented that of all the Diamine colours, if any will be sticky, this is the one. Although, after saying that, I found the some of the Private Reserve inks smear well after you have left the page.

Diamine Ink - Majestic BlueThis ink is wetter than some of the other colours Diamine produces, that means great flow, but a fair amount of ink hits the paper.

Colour swatch from Diamine website is a good representation of the colour of this ink.

So, if this ink works for you, then you got yourself a great blue. The time to dry is a concern

Mediterranean Blue

Mediterranean Blue

This is an interesting colour, a light, soft tone but with a bit of character. It looks very good on personal notes or cards. I have received some emails from individuals asking why I have not said more about this ink. My comments are limited as my use of the ink is relatively limited. The limited use is because I lean towards inks with darker blue tones.

Mediterranean Blue work well in a variety of pens. The performance was good, and the ink had a reasonable dry time on most papers with no smearing issues.

Marine Blue

Marine Blue

This is part of the turquoise group of blue inks. It is a little lighter in tone that the Havasu Turquoise but the ink has what I call an "easy on the eye" look to it. I have used it in both business and personal note purposes.

Performance of the ink was fairly consistent with the Diamine line. It has worked well in a variety of pens, has a reasonable dry time (under 5 seconds) and does not end up sticky.

The one bottle I have was used at the office for a couple of days. Rather than use this colour, I found that I was using the Havasu Turquoise which has much punch in terms of colour tone.

Havasu Turquoise vs Marine Blue

Midnight Blue

Midnight Blue

This is another colour that I have like because of the rich dark tones. It came out in 2009 and is probably my replacement of Majestic Blue.

Diamine - Midnight Blue InkA very dark, rich blue, black. Leaves a great dark solid line of ink on the page.

Not much shading, despite the width of the nib that is being used to write.


Presidential Blue

Diamine Ink - Presidential BluePresidential Blue has a darker tone than say Royal Blue or Washable Blue, and has what I would call a solid look to it.

Darker in colour tone than Florida or Royal Blue. Because of the toner, this ink, from my preference, stands on the paper better. I look at a page of notes and they look good and strong.

Diamine Ink - Presidential BlueThe colour is not as dark as the web HTML colour for Presidential Blue, but overall the ink has a good look.

I have had limited use of this ink using it for a day at the office.


Prussian Blue

Prussian Blue

Prussian Blue is close to a lighter blue-black colour. When I gave this ink a full day's test at the office I concluded it was really a gray ink. In fact one day I held asked for feedback from a co-worker and it was a resounding: gray not blue black.

When I have scanned ink samples there are hints of blue that come on on the scan, but not so in actual writing. I think this is more of a personal stationery ink. In the office, I noticed that because of the gray tone, for letters I signed with this ink, the signature did not photocopy very well.

The ink has good performance, it dries very quickly, a little quicker than some of the other colours.

Despite the various pens I have used, the ink just never looks as dark as the colour swatch on the Diamine web site. I have written with a Pelikan M1000 with a Broad Nib, now that is a pen that really drops a fair amount of ink on the page. Still, no where near the color swatch.

Royal Blue

Diamine Ink - Royal BlueRoyal Blue is an easy-on-the-eye blue with good colour although this ink is what I refer to as a very light blue.

I have used this for personal writing and it looks very good on a card for a few lines of text. But when I have used it at the office for meeting or hearing notes I have found that pages of meeting notes look pale to my liking. There is not enough punch to the colour. I lean towards a darker, stronger colour.

Generally the performance was good and I did not encounter any problems with any particular brand of pen I used for the day's test (Waterman, OMAS). The dry time for the ink was reasonable.

Colour swatch from Diamine website is a good representation of the colour although when I write with the ink it always seemed to come out lighter in tone than the swatch.


Sargasso Sea

Sargasso Sea

I ordered so more ink a few weeks ago, and came across a sample of Sargasso Sea, which looked like a bold blue.

Sargasso SeaWell it has arrived, and I have been using it for a few days and this certainly is a blue that grabs my interest. I am watching its performance carefully. There was a bit of the performance of Majestic Blue, but on the right paper the ink is a winner. Some days in the office, with cheaper copier paper I have not been as happy.

The only caution that I make about this ink is that it dries in the pen. Leave the pen uncapped, especially with a large nib, and it will take a few strokes to get the ink going again


Sapphire Blue

Sapphire Blue

Sapphire Blue - this is a good colour if you like bold colours as the ink stands out on the page. As the ink dries on the paper a bit more of the blue tone comes out, but when you start to write with it, purple is the colour that hits you.

The ink has a good flow quality, it nicely leaves the nib and lays and good line of ink on the paper. There is some bleeding on a range of papers. Of course, your individual experience will be influenced by the paper you use.

Diamine Sapphire BlueMy most recent writing with this ink was with the Pelikan M1000 Broad nib and there was a bit of feathering of the characters of the words - but I must recognize that a fair amount of ink is laid on the paper with the M1000 nib. But to test the ink, I changed inks and the same pen on the same paper did not have that degree of experience.


Steel Blue

Diamine Steel BlueSteel Blue was one of the initial colours I ordered from Diamine.

The colour is not what I expected but it has certainly grown on me and I have enjoyed using it at work and for some personal notes.

My experience with this ink is a bit more green comes across than the colour sample on Diamine's website. The colour sample that is on the Diamine website has a bit more blue than what I have found in using the ink.



Diamine Ink - TurquoiseTurquoise is slightly darker than the Aqua Blue ink.

Overall, good tone, and enough depth of colour that it will "hold a message" as soon brands have a turquoise that seems to visually fade away.

In terms of overall performance, the ink has been working well in the various brands of pens it has been cycling through. There is reasonable good dry time and I have not encountered any problems with smearing.

Diameine Tourquoise InkI have really enjoyed this ink and it will be one of the colours for my next order from Diamine.

The ink does not look like the colour swatch on the Diamine website as the colour sample has more blue tones than my experience with the ink.




I have always liked blue-black ink. This ink I have enjoyed using. I always like richness in the tone. This is good in that aspect. As the ink dries, there is a bit of a blue-gray look that is left on the page. The ink has a soft appearance on the eye. Nothing jarring.

In terms of performance, this ink has been performing very well in various pens that I have been using the ink (OMAS, Mongtegrappa, Waterman, Aurora, Pelikan).

I am using this ink regularly and I show how the ink is in terms of time to dry. On the left I ran my finger across the writing after 5 seconds, and on the right, I wrote again, and then ran my finger over the writing after 10 seconds. So between a 5 to 10 second dry time on the paper. That is not bad, again, I am using a broad or Italic nib so there is a fair amount of ink hitting the paper.


The colour sample on the Diamine web site is fairly good, but it shows more blue than I have experience in using the ink. Interestingly, I also use the Blue Black by Diamine, and these two colours are very close. I show the colour sample from the Diamine website to the right .

Blue Black - Diamine Ink - glennspens.com - Ink ReviewsI look at the Blue Black and it is somewhat darker in tone. My wife, who is an artist, says the Twilight has a green/gray undertone to the colour and finds the Blue Black a darker and more true Blue Black.

So there you go, lots of comparison on this colour.

I am continuing to use this ink and so far enjoying the colour and performance of the ink.


Washable Blue

Diamine - Washable BlueThis ink has a flat soft look. It is easy on the eye, although for my preference, I prefer a blue with a little more punch. In terms of use, I have used this ink to a limited degree.

For many this could be a good mid-tone blue.

I not sure what the Washable really stands for. All the Diamine inks are water based so none or water resistant. Some, I have noticed from getting ink on my fingers need a bit more of a scrub to get off.

Washable Blue - After a Wet Finger'So I took my finger, dipped it in water, and then immediately ran it across the Words: Washable Blue. I was expecting the ink to just lift off and paper and float away. Not so as the example to the left shows.

The colour sample on the web site is a bit darker than what I see in using the ink.


WES Kensington Blue

WES Kensington BlueDiamine made this ink for London's Writing Equipment Society (WES).

This is an interesting blue, although you do no see the tone on the colour swatch on the Diamine web site, when you write with the ink, there is a turquoise tone to the colour.

The ink performs well, although in terms of drying, this colour I found dries quicker than some of the other colours Diamine issues

I have only tried one bottle of this ink, and when I want to use a turquoise ink, this one has been a good choice.

Diamine - Washable Blue The colour swatch on the Diamine website is not a good representation of the colour of the ink because it shows much more blue tones that I found in using ink, from the one bottle that I have.
