Flower/Fireworks Obsidian Rough Chunk! Gary Green This fossil is perfectly stable

This fossil is perfectly stable as is

this beautiful and stunning jasper could no longer be mined

with the bone cell structure often present and well preserved

and it also takes a mirror grade polish as it is a volcanic glass

Each one in this is a high potential cutter rough chunk

Flower/Fireworks Obsidian Rough Chunk! Gary Green This fossil is perfectly stableFireworks Obsidian also goes by the name of Flower Obsidian. It is a very rare form of natural volcanic glass Obsidian found in Mexico. It has a very high mineral content, which gives this material its gorgeous pattern and colors! It often has chrysanthemum like flowering with a black or pink backdrop. It can take a decent polish, but with the impurities giving it this crazy display, it can often be fractured and pitted and may need to be stabilized
