Obsidian

per 6mm bead
Volcanic glass — the oldest edge humans ever made.
Obsidian is lava that cooled too fast to become a crystal, which makes it glass rather than mineral. Knapped obsidian blades are sharper than surgical steel, and people were making them long before they were writing anything down. In crystal tradition it is the boundary stone: worn to mark where you end and the rest of the day begins.

5.5 Mohs and it is glass: it scratches easily and can chip to a genuinely sharp edge. Store it alone, and retire a bead if it chips rather than wearing it.
