Color: A very dark gray blue with bronze-brown sheen, particularly in areas where the ink pools.
Special Note: Although Diamine classifies this as a standard ink, it noticeably very sheen-ie. The sheen can take a long time to dry, especially in areas where the ink pools. Be careful when closing your journal or touching the writing, as it may still transfer or smudge after the base ink appears dry.
Inspiration & Background: Originally released as Day 13 of the Diamine Inkvent 2025 Teal Edition. The name refers to basalt, a dark volcanic rock formed from cooled lava.
