Diamine Ink: History & Cult Pens Deep Dark Blue

When it comes to choosing a new ink for your fountain pen, the name that nearly always comes to mind, is Diamine. But what is the history of Diamine, when was it established and just how many ink colours have they developed? We took the opportunity to ask Christine & Phil from Diamine these questions as well as putting them to the test by creating Cult Pens Deep Dark Blue. Read on to find out more...


Diamine Inks

Cult Pens: What's the history of Diamine, how did it all begin?

Diamine: T.W. Webster Co. Ltd., was established in 1864 with Diamine as their trade mark. Ink for pens was supplied in stone jars to all the schools and banks at that time. After the introduction of the ball point pen, the company went in other directions producing alternative ink products for industry. You can find out more about the history of Diamine on the website.

Diamine BuildingCult Pens: Diamine has gone through a lot of transition, what do you think have been the key factors in its revival?

Diamine: Diamine Inks is experiencing a very exciting revival, the late 1990's showed renewed interest in fountain pen ink products and as a result the Diamine fountain pen ink brand was re-launched with the sole purpose of introducing a more exciting range of colours than had previously been available.

Cult Pens: How have the processing techniques changed or are elements still incorporated in the factory today?

Diamine: Our inks are manufactured using traditional methods, only changing the original formulas where necessary to comply with current legislation.

Cult Pens: How many colours do Diamine offer?

Diamine: We currently offer 110 colours under the Diamine Brand and many more as exclusive/own brand to other companies.

Cult Pens: Does Diamine have a favourite ink colour, or one they are most proud of?

Diamine: The ink colour which we are most proud of is Ancient Copper, this ink has no exciting story behind it but from a popularity point of view it has been a massive success. It is at the moment the best-selling Diamine ink on the market.

Cult Pens: How do you go about choosing/selecting a new colour?

Diamine: We try to find out what customers actually want, this plays a large part in which direction we go in when choosing a new ink.

Diamine's Famous ColoursCult Pens: Who are some famous Diamine users?

Diamine: Not sure, but hopefully there are some well known faces out there who use it!! We do have three famous colours:

  • Monaco Red: Specially formulated for his Serene Highness Prince Rainier III of Monaco and the Grimaldi family in conjunction with a presentation of a limited edition fountain pen.
  • W.E.S. Imperial Blue: This special edition colour was introduced on request for the 25th anniversary of the Writing Equipment Society
  • Royal Blue: This ink was used on April 2010 by Presidents Obama/Medvedev in the signing of the nuclear arms treaty at Prague Castel.

Cult Pens: What was the inspiration behind the Music Collection Ink Set and do you have plans for other collections in the future?

Diamine: We wanted a set of inks with an inspirational feel. The Music set is the 1st in a series of themed sets that will be available over the next few years the 2nd will be launched Autumn 2013

Cult Pens: What is the future for Diamine?

Diamine: Our aim for the future is to continue to supply a high quality, affordable fountain pen ink product which meets the expectations of all our customers.

Thanks to Diamine for taking the time to answer our questions.

Cult Pens Deep Dark Blue - Special Edition Diamine Ink

We have always liked the deep, dark colour of the Cult Pens logo but have struggled to find an ink that matched it for depth. Sure there are plenty of blues out there, but a Cult Pens blue? No. That however, is now no longer the case!

We are pleased to announce that Diamine have concocted... Deep Dark Blue, a special edition ink that we think matches our logo down to a tee.

Deep Dark Blue

We only have a limited amount of Cult Pens Deep Dark Blue bottled (80ml) available, go get yours while stocks last! Who knows, if you like it, we might stock it permanently :)

**Update - Thankfully you really liked our Deep Dark Blue, so we now stock it permanently, and have added more colours to the Deep Dark range. You can see them all here.**
