Tri-Flow Obsidian Rough Chunk! Larsonite The last time a chunk

The last time a chunk of Crayola was found was in 2011

and is of course excellent for knapping as well

but the color and wood pattern usually make it well worth while to work around

It typically takes a decent polish

It is a pretty hard jasper

Tri-Flow Obsidian Rough Chunk!

Tri Flow can make some designer grade cabochons, as the obsidian between is often pure and almost completely see through when held to light or cut thin enough, and the waves of pattern are often in layers! The color generally comes from Magnetite that was present in the lava flow! Tri Flow Obsidian is
