Diamine Blue Pearl is from the original 2015 Diamine Shimmertastics Collection. I purchased my sample of ink from Vanness Pens.
Blue Pearl is a dark blue with silver shimmer.
There is a lovely red sheen that shows up in the ink drops.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper there was a little bit of feathering but other than that the ink performed well.
I used a Pelikan M400 White Tortoise with a vintage 400N nib on Tomoe River paper. I really enjoyed this ink/paper/pen combo.
The ink had an average to slightly wet flow. The shimmer in this ink felt a little more consistent than some of the other Diamine Shimmertastics.
Overall, I liked this ink. The sheen is nice, and I like that it has silver shimmer, which I prefer most of the time over gold shimmer.
