Pyramidal Blue Lace Agate w/ a natural vug containing a druzy crystal form

Blue Lace Agate, a variety of banded chalcedony (microcrystalline quartz). It has been cut and polished into a self-standing "tower" or "obelisk" shape with a flat base and a pointed top. The unique feature is a natural cavity (vug) where sparkling (druzy) crystals have formed, accompanied by natural iron staining, giving it a golden-brown appearance.
