Caveat: this year’s Inkvent appears to have elusive ink colours. I suggest reading my description of the inks and not going by the photos alone, and comparing my results with those of other reviewers.
The Diamine Inkvent calendar is an advent calendar with 24 tiny (12ml) bottles of fountain pen ink behind 24 doors, and a larger, 30ml, bottle of ink behind the 25th door. All the inks are limited edition, and, at the moment, only available through this calendar.
Day 12’s ink is Diamine Stargazer. It’s a navy/denim blue with a red sheen and a blue shimmer.
Shimmer and sheen.
I used a Diplomat Aero Champagne with a fine nib to test out Diamine Stargazer.
Here’s a better view of the red sheen and the blue shimmer:
I decided to draw an astronaut and rover gazing onto a field of random stars to test this ink out. There is some shading, but it’s hard to see it with the sheen and shimmer that’s going on.
This was drawn on a Kanso Sasshi 3.5” x 5.5” Tomoe River Paper notebook (the notebooks I have were bought in 2016, and so they contain the old Tomoe River paper).
Finally, I wrote a page in my Midori Journal:
Diamine Stargazer can pass as a “serious” ink quite easily because of its base dark blue colour. I don’t need another ink in this shade, but if I did, I would probably buy a bottle of this ink, because it’s such a fun twist on a “office appropriate” ink colour.
