Ink Review: Lamy Crystal Obsidian

By Jessica Coles

When I first heard about Lamy’s new Crystal ink line I was excited because, hey, new ink! Even when the Lamy showed the colors of the ink line in their advertising, I remained excited.  But when I started to see swabs of the colors, my enthusiasm started to wane since the colors seemed to have issues: one was a repeat of a special edition (Rhodonite), another missed the purple mark (Azurite) or colors that are very close to other brands (Amazonite). However, there have also been winning colors in the line (Agate) that are quite original.  I would place Lamy Crystal Obsidian ($14 for 30mL at Vanness) in the latter category.

The band at the bottom of the cap blends in with the black ink of the bottle, but I appreciate the detail. The is packaged securely within the box and should have no trouble with broken bottles during shipping.

I love the look of the bottle and they store nicely next to one another, but the bottle itself is not particularly shaped well for filling a pen. If you are filling a converter, the shallow bottle is quite nice.  Filling directly into the pen, whether it is a converter pen or a piston filler, the bottle presents a challenge.

Lamy Crystal Obsidian is a lovely ink that gets the deep black from the blue section of the spectrum.  However, during normal writing, there was no indication of the blue undertones.  Obsidian is a deep, true black.

The dry time is longer than I usually see with Lamy inks, taking about 30 seconds to dry.  You can see where I became impatient above! 

The only time I experienced any indication of possible bleed-through was when I dropped water on a heavy patch of the ink.  Although some of the ink did wipe away, this was excess dye.  Lamy Crystal Obsidian should be quite readable even after a liquid dunk.

Obsidian is a semi-precious volcanic glass that can hold an incredibly sharp edge.  There is no sheen with Obsidian, although the edge could be said to be present in the crisp writing – in other words, no feathering.


I found Lamy Crystal Obsidian to be a delightfully black ink that needed to be a part of my obsession collection. True black inks are hard to come across, especially one that is easy to clean out of a pen.

My favorite black has been Sailor Kiwa-guro even though it can be difficult to fully clean out of a pen.  Since it is pigmented, it is water-resistant but needs extra attention while cleaning. Kiwa-guro also has a bit of a sheen which keeps it from looking truly black in some lighting.  I’ve also had the same issue below with Platinum Carbon Black – some lighting makes the black look faded (although it doesn’t appear so in person). Lamy Crystal Obsidian, however, seems to absorb any light thrown it’s way.

I highly recommend Obsidian as a valuable addition to your ink line.  I have kept a pen inked with it since purchasing my bottle – I always seem to find a need for black ink throughout my day. Plus, how hard can it be to use up the smaller 30mL bottle!

  1. Hi, Jessica! Thanks for the review. I just got my first gold nib pen, a Lamy 2000 in medium, and I’m struggling to decide on a black ink. I like ‘em dark, so I’ve been looking at this, Aurora black, and a few others. I have and love Platinum carbon black, but don’t want to do extra maintenance on a pen that isn’t meant to be disassembled. Any favorites you can suggest for my new setup? Thanks!
