Diamine Cobalt Jazz is another ink from the 2017 Diamine Shimmertastic collection. I'm so close to having the full collection reviewed. I purchased my sample of ink from Vanness Pens.
Cobalt Jazz is a medium blue with dark pink sheen and gold shimmer.
The ink drops show off the bright sheen and gold shimmer.
Dry time: 45 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper there was a tiny bit of feathering, but other than that the ink behaved pretty well.
I used a medium Edison Nouveau Premier Delphinium on Tomoe River paper. The ink behaved really well, but was a little on the wet side.
Overall, I really like this one-it's nice and bright and has some interesting sheen and shimmer.
