Ink Review #1231: Diamine Sargasso Sea

Now that we’ve finally made it through the Diamine Inkvent Calendar we can get back to regular reviews, starting with Diamine Sargasso Sea. I purchased my bottle of ink from Cult Pens, but you can find this ink for sale at most US retailers, including Vanness Pens.

The color:

Sargasso Sea is a bright royal blue.

Swabs:

In large swabs on Tomoe River paper the ink has some pretty coppery sheen.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 5 seconds

Water resistance: Medium

Feathering: Low

Show through: Medium

Bleeding: None

Other properties: no shading, high copper sheen, and no shimmer.

On Staples 24 lb copy paper there was some feathering and bleeding in all nib sizes.

Comparison Swabs:

Sargasso Sea seems like a darker version of Diamine Royal Blue. Click here to see the Diamine inks together, and click here to see the blue inks together.

Longer writing:

I used a Bonecrusher Studios pen with a Regalia Writing Labs Crossflex nib on a Taroko Enigma notebook. The ink had a wet flow.

Overall, this is a fun sheeny ink but it is prone to a bit of smearing on Tomoe River paper. It’s a fun ink, but it’ll never be an everyday ink for me.
