Petrified agatized dinosaur bone 20mm round fully drilled bead gem focal piece
I got this bead back in the late'80s or very early 90's and it has been sitting in my personal collection ever since unused. It is a rare gorgeous 20mm round fully drilled bead made from petrified (agatized) dinosaur bone.
I do not know specifically where the bone was from but but I do know that the lapidarist who cut it was in the US and used US sourced rough. A stunning focal gem bead or just an awesome collectible.
