The ink is very well-behaved. It's well lubricated and glides easily across the page. At the same time, it isn't overly wet, which can cause feathering and bleeding. The only bleeding I've observed with this ink was when I used a watercolor brush to glop ink onto the Rhodia paper for a test. When writing, there have been zero issues. It doesn't even show through on the back of the page as much as I'd expect from a darker ink. Once again, incredible!
In all, I'm really impressed by Healing Stone. It's not my favorite color, but I've enjoyed using it due to the shading variation and crisp lines it achieves. Add in the quick dry time, and it's a complete winner.
I wish I could point you to a link to buy your own bottle of this fantastic ink, but it isn't current for sale. I don't have the details about when/if this in will be available for sale (or what other plans Vanness may have for the ink market), but I hope that this isn't the last we hear from Vanness in terms of interesting inks.
