Diamine Ink for Fountain Pens - 80 ml Bottle - Sargasso Sea Blue

This is a deep blue ink with a GORGEOUS golden sheen. It's truly reminiscent of the light from a sunset reflecting off lazy ocean waves.

I find Bilberry Blue to be a very attractive dark blue ink. It satisfies my desire for an ink which is truly blue, although very dark, with no overt evidence of black or teal. The color delights me. Worth the buy if you feel strongly about dark blue ink. For example, if you think Sheaffer blue is a very nice color, but not quite dark enough for all purposes, this might be what you're looking for.

Flows very well in my Plaisir and Lamy pens and I used this ink with a glass dip pen. A wetter nib might show color variation more easily but I have not observed much variation on the few pages I have written so far. A 'fun' purple for happy correspondence - if you prefer a more subdued, 'conservative' color that is purple I have tried the J. Herbin Poussiere De Lune and it is much less 'showy' than this color.

Diamine's "Oxblood" is a very dark maroon/burgundy color. On glossy bright white paper, it'll be an amazing nearly-dry blood color, especially if your pen is wet enough to have it bead up nicely at the ends of strokes. On matte paper, where colors always look darker, it'll be a reddish-black (the color of a ripe dark cherry's skin.)

It reminds me of the "Burgundy" color of the Marvy/Uchida Calligraphy markers. It's darker than the Kuretake Zig Letter Pen CocoIro's "Bordeaux" color (which JetPens sells as "blood red".)

I think this is the darkest red in the current Diamine range. If you want a red that's a little more vivid, you might consider Diamine's "Maroon".

The bottle is, as expected, heavy glass with a hard plastic cap, but note that you might not get the marbled green cap shown in the photos here -- my bottle has a solid black cap.

Lovely smooth flowing ink. Be advised this is not true blue black but that's not what I wanted. I would say it is more of a deep dark teal color (again exactly what I was looking for). I think the picture of the inks is very accurate for the color. I ordered this after a reccommendation from jetpens and it was just what I was looking for. LOVE this ink. LOVE jetpens!
