2ml sample of Diamine Night Sky shimmering fountain pen ink, in a labeled plastic vial. Black with silver shimmer.

Due to the amount of particulate in this ink used to achieve the sparking look, you may experience restricted ink flow in some of your pens. We recommend shaking the ink thoroughly before filling and gently rolling the pen in your hands often to keep the shimmer effect consistent. This will also help prevent clogging. You will also want to be diligent about cleaning and maintaining your pen when using this ink.

friendly a.
talented brilliant incredible amazing show stopping gorgeous

This is not the silvery-gray glitter bomb that you'd expect in the swatch, but a rich and saturated black with just enough glitter that it looks, well, like the night sky. I would swear that the "silver shimmer" has ever-so-subtle green and purple specks in it. This is a well-behaved, well-lubricated ink that flows great even when I was drawing with my broad nib upside-down... effectively a fine nib at that point and not a single clog or stutter.

good shimmering ink

For me it comes out as a medium grey color with nice shimmer to it. It's kind of a subtle shimmer but nice effect.


The items ordered arrived in a very timely manner. The packaging was very nice! They took the extra step to make me feel appreciated and cared for as a new costumer. I will definitely be buying from Goulet again!

Very wet, good line, and subtle sparkle

My daughter was interested in this color, and I picked some up for her to try. The ink was very nice, but the shimmer is pretty subtle, so if you aren't laying down swatches of the stuff, don't expect a high silver look. Instead, you can expect a solid, saturated black with a silver-ish sheen to it.

More black than grey.

A little darker than I thought, but still a beautiful ink. This looks black in person with some silver shimmer in it. I thought it would be more grey than black, but still worth investing in!

FAQ about Ink Samples

How do I fill my fountain pen from an ink sample vial? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the fountain pen's filling mechanism.

Check out our blog post on How to Fill a Fountain Pen from an Ink Sample Vial.

How much writing can I do with 2ml of ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It really depends on how big or small you write, and the nib size you’re using. We find that usually you can get 2 good fills for a typical converter with our Ink samples, or one good fill with a piston-filling pen. How much writing depends on you more than anything else, so we recommend experimenting with different nib sizes to find what works best for you. 

What is shading, sheening, or shimmering ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Shading - A common (and often desired) result of a fountain pen ink pooling in certain parts of a letter when writing, so that the color and saturation of the ink appears different within a single letter or word. This characteristic cannot be achieved with ballpoint or rollerball pens and is a very appealing aspect of fountain pen use for those particularly drawn to all the pretty ink colors.

Sheen - Characteristic of a fountain pen ink where when ink pools another color can be seen on top of the ink, especially when looked at in different light angles using certain paper types. There is no way to guarantee an ink will sheen, but using a larger nib on a pen will help obtain sheening results in your writing.

Shimmering - Fountain pen ink that has small particles of glitter mixed in.

Is shimmering ink safe to use in fountain pens? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

Yes! Shimmering ink is a great way to add some flare to your writing. We have found that a larger nib will showcase more shimmering particles while writing, but you can use any nib size and shimmering ink. All the ink we sell is safe for use in fountain pens.
