Each year Pelikan releases a new Edelstein ink. This year the new ink is Pelikan Edelstein Olivine. I purchased my sample of ink from Vanness Pens.
Olivine is a dark green. It's not quite an olive green, but not quite a forest green either.
In large swabs you can see a little bit of a blue undertone.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 50 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper the ink behaved well.
Ink swabs for comparison, left to right (top to bottom for mobile RSS): Diamine Green Umber, Pelikan Edelstein Olivine, and Diamine Green/Black. Click here to see the Pelikan inks together. I think Diamine Green/Black is the closest in color.
I used a medium Pelikan M400 White Tortoise on Tomoe River paper. The ink had an average flow.
Overall, it's an interesting color. It's well behaved, but the dry time is just a bit long.
