My latest ink is Diamine Ruby

Diamine Ruby is another very good red ink. It's not quite as bright or as eye-catching as Wild Strawberry, or Classic Red, but Ruby is still a nice, red. It's a well behaved ink in all of the pens and on all of the paper I tried it with. It's not overly saturated but I saw plenty of attractive shading. It goes even further towards the pink end of the colour spectrum, and could easily be described as cherry or dark pink. It is certainly the colour of rubies though, so it's another ink that does exactly what it says on the bottle.
It wrote straight away without any hard starts or skipping. The flow is very good and so is it's lubrication at the nib. Although the flow feels slightly different to Wild Strawberry and Classic Red, it didn't feel at all dry. The dry time was quite quick and there were no smears after it was dry. However, it was a warm day when I did the review.
It has virtually no water resistance at all. The red inky water spread very quickly.
I think it's a very nice pink/red ink, especially if you prefer pink leaning reds. Kaweco Ruby Red was the most similar colour, but that leans more purple than Ruby, and is less saturated.


  • This isn't sold as a waterproof ink,and shows no noticeable water resistance.
  • Bearing in mind the paper I use is thick with a shiny surface, and I used a Lamy M nib, a Parker B nib and a Waterman F nib this ink only took 14-15 secs to dry. No smear when dry.
  • It exhibited very good flow and lubrication and I found it well behaved to write with. I saw no skips or hard starts while I did my swabs and dry time tests.
  • It is currently available in 80ml glass bottles or 30ml plastic bottles
  • Diamine sell it directly to end-users on their web-site.
  • It's a reasonable price.

Thanks for your nice review. I really like Diamine Ruby but being an Ink addict I'm also looking for similar inks. Out of the 4 inks in your comparison looks like the closest to Ruby is Diamine Classic Red.

Can you please elaborate a bit on which differences you see between the two inks?


Thanks in advance

My two ten fingers on a typewriter computer keyboard have never connected with my brain heart.

My hand on a pen does. A fountain pen, of course.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
