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 4’s ink is Diamine Tempest. It’s a shimmering ink in an indigo/blue black colour with silver sparkles in it.

Here’s a Col-o-Ring swab of Diamine Tempest. It was photographed slightly lighter than it appears in real life. The basic colour is a gorgeous and rich Indigo or blue-black, and the shimmer is subdued enough to allow the ink’s shading to show through.

I used a Lamy Safari Terracotta with a fine nib to test this ink out.

I had to draw a ship in a tempest to test out this ink. It’s quite a dark ink, and the shimmer isn’t in your face – it reminds me of last Inkvent’s Diamine Solstice.

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:

This is not a festive or cheery ink, but I still love it. Something about having such a dark and “serious” colour paired with a subtle shimmer really speaks to me, and I’m quite likely to buy a full bottle of Diamine Tempest should I get the opportunity to.
