You will receive the piece pictured.

Obsidian is a naturally occurring volcanic glass that forms when silica-rich lava cools so rapidly that mineral crystals do not have enough time to grow.

Historically, obsidian - including varieties sourced or traded through South America - was prized by ancient civilisations for its conchoidal fracture, which produces edges sharper than a steel razor.

This piece has one face polished.
