Love this color but cartridges I bought were defective. Manufacturing error. Some were clear, some blue and some red. Buy bottles and fill your own cartridges.

Very nice color out of all the turquoise inks you had that was my favorite

Very consistent color, what you see is what you get. Its a little more green that a turquoise, however it is still very, very blue. Diamine makes very consistent and standard style of inks. Flow is average, dry time is average, and this comes with no complaints! At the price point a better deal is hard to find. Its a great every-day ink for jotting things down or for taking notes.

This ink is drier than any other Diamine ink I've used, or even the famous dry Pelikan 4001 series inks. It looks fine when used on absorbent sketch pad paper, but if you try to use this on normal run of the mill paper with a 1.4mm stub, you will be surprised at how much it skips. You have to write very slowly or else it will skitter and lay down a very faint, invisible dotted line if you try to write speedily. After testing with various paper types and different nibs and pens, I realized that the problem was the ink, and put it into my Pilot Parallel hacked pen that gushes and burps like crazy. And lo and behold, it has tamed the Parallel! If you need a VERY dry ink to tame uncontrollable gushing on a very wet nib/pen, use this ink. If you want ink that you want to be able to write on a normal sized (or normal stub) nib, or tend to write quite fast, this ink is not for you. This is not a verdict on all Diamines; Marine, in particular, is very dry, but other Diamines seem to be average wetness that can handle fast writing just fine. The color is bright and vibrant. Not something I'd use every day but it's a nice change of pace if you're tired of dark inks. It's a true turquoise with a neon sort of brightness.

I was looking for a greenish-turquoise ink and this did not dissappoint! It has lovely shading and is exactly what I was looking for.

Lovely color, sorry I waited so long to order a bottle!

I love all of Diamine's ink. This is a gorgeous shade that leans more blue than Diamine's Soft Mint. I think I prefer this over the soft mint. Nice wet writing ink in my Lamy 2000!

Loved it! Wish I had gotten some other colors.

Good quality ink. Very nice color - a nice change of pace for me (distinctive). Flow seems a bit less pronounced vs. Diamine blue velvet. Seemed to improve with time in the pen.

This is probably my favorite ink in the greens. The color is so beautiful and it has a wonderful flow.

What a gorgeous color! A perfect neutral teal with wonderful shading. Also, it performs well in the pen. I keep this in a Kaweco Sport that I converted to an eye dropper. It's a demonstrator so I love being able to see this ink through the body. Looks great in the pen and on paper. I see why Brian loves this so much! A must have for your collection!

Works beautifully in my Waterman pen

I love this color and shading. My go to color on the regular.

I grabbed this bottle as an impulse to bolster my ridiculous collection of inks. I'm extremely happy with it.

Really nice turquoise ink, a bit more green to it than Diamine Aqua Lagoon. Nice flow and good shading.

It is a majestic beautiful ink that is 10 times better than any other blue i have seen.

I think Diamine is my favorite ink brand so far! They have so many nice colors, and the ink seems to flow really well. Marine is no exception. I bought this to go with my Pilot Metropolitan Retro Pop Turquoise. It's a *pretty* good match, not absolutely perfect, but it's close! I really like that this ink seems to have a lot of green in it.

I was torn between the huge selection of inks in this general color that are available from this site, so I took a shot in the dark after spending way too much time thinking about it. This ink is so good. This brand is always a pleasure to write with. The color is exactly the same as it's pictured here, and it behaves beautifully. I intended to use this ink for work purposes, but I've decided it's much too pretty to be wasting on silly work forms.

I finally was able to buy a bottle Diamine Marine ink - it had been out of stock for a while. I am addicted to the various Blue and Turquoise colored inks. The Diamine Marine is just wonderful and it has that blue-greenish shade to it that is just fantastic! I am currently using it in my TWSBI Vac Mini and my Pilot E95s; the Diamine Marine flows evenly and consistently. Dries quickly and has some nice shading with the wider nib's. I have used Diamine Marine in 4 different pens and each pen presents with distinctive differences that add to the allure of this magnificent fountain pen ink.

This is a great color. Has a great flow in my Lamy Safari. It is a very distinct turquoise. You can tell there is green in it. A great bottle as well.

Like this color a lot as it reminds me of carribean waters; it flows great withPreppy fine nib, and even better with a Sheaffer 100 medium nib;

Excellent bright color...easy to read but stands out

I am a blue-green ink enthusiast, so I decided to add Diamine Marine to my (quite large) ink palette. It is a very nice relatively light blue-green, with a very nice shade, depending on the wetness of your pen. It is actually very similar to Diamine Steel Blue, but a little bit darker and leaving a darker shade. Also similar to Private Reserve Blue Suede, but lighter; in the same range of blue-green though. As most Diamine inks it dries reasonably fast and does not produce feathering. With the right paper It is a real nice ink for notes and general writing purposes. I use it also for correcting and grading papers, which gives a very attractive highlight to the corrections in papers that are generally written with dark inks.

I love this ink. So dark that it can be used where black or blue black would be, but much more interesting. Has turquoise depths like a moonlit sea. Some lovely shading with a flex nib. Very well-behaved.

I had a new pen and, of course, I wanted a new ink to go with it. It's hard to choose sometimes because you never know what the actual ink will look like compared to what you see on your monitor. Fortunately, I was going through some old bills and found one of Brian's handwritten thank you notes written in this color. Beautiful looking, easy writing - everything you'd want in an ink!

Right away, this was my favorite sample from the April Ink Drop and I was in suspense waiting to find out what it was. I love the brilliance of the color and the subtle shading, and it flows well in all of the pens I've tried so far. Normally I am not a fan of blue inks, but this one is more on the aqua or teal side and it reminds me of a summer ocean breeze. Or the sea glass one might find on the beach. Lovely.

I find the ink is less smooth with some bleeding on a bond paper than some other brands I've used.

First, the chemistry: Flows well in several pens. I write almost exclusively with italic nibs & this ink shades beautifully. I'm reporting that after using it on Clairfontaine and the Rhodia Webnotebook. No feathering or bleed through on either of them.Second, the aesthetics: I'm not sure I like this incredible color. I can't book a trip to Micronesia or the Caribbean and when I use it that's all I can think of. It's stunning. I've had too many what Scheaffer used to call Peacock Blue. This is a bit more green than the majority of turquoise inks. I really can't liken the color to anything other ink color. Marine is an apt name as it is like one of the colors in tropical oceans (Very close to the swab as my monitor shows it - as usual, kudos to Brian and his staff.) I'd never use it for any business purpose tho'. I hear that Polynesians have one hundred or more words for blue. Sad that English is so limited. This color would surely have a unique word for it.

I love my new ink color - it's beautiful! My husband and son love it, too, and are using it as well!

I love how this ink behaves. It is a beautiful color that is exactly as advertised. I will buy it again in the future.

I have grown to really like Diamine ink. This is a beautiful color and I'm really enjoying it. I'm currently using it in my Lamy Safari with a 1.1mm nib and love the shading it produces. I was looking for a turquoise similar to an old peacock ink I remember from long ago and this one fits the bill.
