On December 28, 2024 my Jade TWSBI Diamond 580ALR (Extra Fine) joined its comrades when it was filled with Lamy Turmaline. The pen was in use for about 11 months and was emptied and cleaned on November 25, 2025, saying good-bye to its fellows.

Thoughts Before Filling

I picked up this pen because I wanted it for my collection, but I also wanted to write with the onyx nib. The pen makes me think of jade more than the Caribbean, and it took me some time to find an ink that I felt was a good match. I’m going to give Lamy Turmaline a try. I have only used this ink once before, so it’s time to give some attention.

Thoughts After Cleaning the Pen

I’m afraid there’s not much to say here. The pen performed admirably and the ink was quite nice. Nothing stood out, however, which is why this took nearly a year to write dry: I kept forgetting I had this one as an option, even though it was resting next to my other pens.
