Anyway, I inked up the pen without any mishaps. Finally, after writing a few more lines, I could see the shimmer. It takes a few seconds for the glistening bits to show up — it must have something to do with the ink drying. Once they show up, they are subtle and require good lighting. For Night Sky, the flakes are silver instead of gold.
The nice thing about the Night Sky ink is that you can still use it in an office setting because of how subtle the shimmering effect is. Unless you're using a large-nibbed, wet fountain pen, it can be easy to miss it. To me, this is a desirable feature since it doesn't completely take over the ink. It's there, but it's not in your face about it. However, if you want the sparkles in your ink to actually light up like a disco ball, this one will disappoint.
That being said, this is a solid ink. The sticker on the bottle is pretty, the price is fair, and it has a neat trick up its sleeve. I'm not sure I'll delve any deeper into Diamine's Shimmering line of inks, but the Night Sky is one that I'll probably dip into every so often to add some flair to an otherwise boring black ink.
The Diamine Shimmering Night Sky comes in a 50 ml bottle for around $20. There are several other colors to the Shimmering series, and feature silver or gold flakes depending on the ink color.
