This is the first ink I’ve tried in the Diamine “Forever” series of water-resistant pigment inks: Cherry Red
It is very bright and seems to be “true” red. Not too dark or too pink when dried. Neither are bad just not what I’m after sometimes.
There seems to be a bit of gold sheen, too, which I didn’t expect (but should have, seems like almost all reds have gold sheen)
Water resistance seems great so far, I’ve had a water drop sitting on a letter until it evaporated with no change. Rubbed a few letters with a wet finger and nothing moved. Had to really exert a bunch of pressure to even get a tiny faint smear but it didn’t affect readability.
Writes a bit on the wet side, especially compared to typical Diamine inks. Could be the pen, though.
The Diamine Forever line of inks are water-resistant pigment inks. Take care when using pigment inks! Use a pen that seals very well or write the pen empty in a short amount of time and clean the pen out promptly, otherwise the pigment particles may cause a clog.
Scans
The scans lack the sheen, as usual, but they make it easier to see shading in some of the lettering and the large swatches.
Photos
These photos show off its sheen. It’s not overpowering, but it is there. The ink is shiny in general, but there is gold sheen among the reflections.
Writing Samples
Writing sample below is on Iroful (top, first) and MD (bottom, second)
Microscope
The gold sheen is even more visible in the microscope photos, along with some shading.
Chromatography

The chromatography is pretty much all red and pink and mostly near the start. That’s to be expected, I suppose, given that it’s a water-resistant pigment ink.

Nothing too noteworthy under UV light, but there is a slight blue halo past the leading edge.

Verdict
This is a great color, one of the brightest and reddest inks I have. It being a pigment ink somewhat limits its utility for me, but occasionally the water-resistance is necessary.
