Agate and Quartz SiO2 is a hard mineral, still it is my fun to light it from the inside..

Looks to be Quartz combined with a jasper like protrusion both SiO2 and some compacted material that has been tumbled through geological time..

Picture focus does not allow detail analysis..

Other then a minor oddity there is no real value..

Here is a quarter of (an agate) geode that cost $2..

Which was tumbled then cut and finished..

You recognize agate also SiO2 <==> silicone-dioxide by those formation lines which under microscopic examination resolve into the thousands of lines..
