Fountain Pen Review: Diplomat Excellence A, Rhombus Guilloch Lapis in Black

Review by Laura Cameron

A few weeks ago, Ana told me she had a pen for review that she thought I would like.  She brought me the Diplomat Excellence A, Rhombus Guilloch Lapis Black Fountain Pen ($225MSRP).  I’m not going to lie; when I first saw the pen I thought “now THAT is a fountain pen!”

When I received the pen, it was truly like opening a present.  The pen comes in a white cardboard box bearing the Diplomat logo. Once “unboxed”, there is a metal sleeve that slides aside to reveal the gorgeous pen sitting on white satin, again with the logo.

The Diplomat pen body is an all-metal casing with a multi-layered lacquer finish and laser engraving.  The nib is a fine steel nib and bears the Diplomat logo.  The postable cap is a screw cap, and the very top of the cap also bears the Diplomat logo as well.

One of the reasons Ana thought I might like to review the pen is because of its weight.  This is a metal pen and has a very pleasing heaviness to it.  The body itself, with converter filled, weighs 29gms and, with the cap, it weighs 45gms.  While the cap is postable, I found that posting the cap made the back end of the pen fairly top heavy, so I preferred not to post it.

This pen was a joy to write with.  The ink filled quickly and the pen itself wrote very smoothly.  The fine nib is more of a Western fine, so not as fine as a Japanese nib, but still very nice.  I really enjoyed the quantity of ink that the pen put down; it gave excellent coverage without being too wet.  I was able to test this pen on both the Crossfield Journal and Field Notes Byline and it performed very well.

To be honest, my favorite thing about this beautiful pen is the thought put into all the little touches, specifically the aesthetically pleasing logo tying all the elements of the pen together. They are executed in a way that isn’t fussy, but really lend an air of elegance to this pen.

  1. I’d first fill it with Bookbinders Snake Ink Ground Rattler. What a lovely shade of purple, and just different enough to be distinctive rather than crazy in a business environment. In fact I think I’d keep filling it with that ink.

  2. Such a smart looking pen. So many fine inks. I’d love to try either the diamine night sky, or pilots kon-peki.

  3. A fill of Herbin Violette Penssee is a great introduction to the world of distinctive writing. My first fine fountain pen was a Diplomat that I wrote out wedding announcements with, on the train to Niagra Falls on February 29, 1980. I use it every anniversary to write a love letter to my wife we are still adventuring together and the Diplomat is a great punctuation point.

  4. I would use Noodler’s Blue Ghost, because I’ve watched people use it and it was the most serene sight I’ve ever watched.

  5. I would be filing that with Pilot Iroshizuku Syo-Ro, dew on pine tree.

    This is an incredibly generous offer for a giveaway, thank you!

  6. I would fill this pen with Kobe #8, Arima Amber because it seems like a festive fall color that would carry well in October and Halloween season.

  7. I have a bottle of Diamine Oxford Blue that is perfectly suited to this pen. I’d fill it and write for hours!

  8. Id make this sexy pen my daily all day work horse pen and fill it with a noodlers dark matter ink and let the pen make the ink better all on its own.

  9. Being a lefty, I have my sturdy Noodler’s 54th Massachusetts to fill it with. If that doesn’t suit me, it at least gives me an excuse to get some new ink haha!

  10. I originally said I’d use Oster’s Moss, but I just got a sample of Kyoto Kokeira and I think it would look awesome with this pen!

  11. I just got in some diamine oxblood, and was going to use it this weekend but i think i will wait and see if I can use it in an awesome new pen!

  12. Ooh…so many inks…and I don’t yet own enough pens…anyhow, Platinum Citrus Black to begin with… Such a beautiful pen deserves an equally stunning and striking ink flowing from it!

    Thank you for such a wonderful opportunity!

  13. Parker Quink, black.

    First, because that’s a classic looking pen, and needs a classic ink.

    Second, I’m away from my ink stash for a few more days and that’s the only name I remember that I’m sure I can spell correctly.

  14. I Wohle fill in the Iroshizuku Yama-Budo, as it is a noble color which fits to the pen, business and shows a different thinking

  15. I think I would fill it with Diamine Oxblood. For whatever reason it seems like it would suit the pen well. Thanks for the chance.
