Ooh, such a beautiful colour! The base colour is similar but brighter than Robert Oster True Blue and Bondi Blue, and not far from Kobe #58 Hyogo Canal Blue.
Kyanite du Népal has a magenta sheen in heavily saturated areas where the ink pools, and also when writing with wet pens in all nib widths, as an outline though—with my pen and paper combos. It also has silver shimmer. It’s a saturated ink but cleans out well from converters, with a few extra flushes to remove the sparkles. I obtained dark, contained, crisp lines with my Sailor 1911L 21 kt H-EF, and the ink is readable in nibs of all widths. My Sailor 1911S 21 kt H-M, my driest pen, played well with this ink, and I actually enjoyed writing with this pen—for once! No feathering, no bleedthrough, some ghosting.
I don’t care much for shimmering inks, so I decanted a few of my samples and discarded the sparkles, after first trying it out as is with my H-EF nib: the ink flowed well and it didn’t clog the pen, even after letting it sit in the pen for over a week. I had to shake the pen to evenly disperse the shimmer; the pen started right away.
Kyanite du Népal coats the nibs extremely well, and feels smooth even on textured paper; writing with this ink feels like applying silicone-based cream on the skin, where the fingers glide across it like they would on silk; a little goes a long way.
I’m head over heels for this ink! It calls to me just like the singing of the Sirens, but I have no Orpheus to save me…
