This Large Volcano Agate sphere 154mm weighs 4980g. This large sphere was shaped from rock formed in a volcanic environment. This formation gives it features that differ from more common agates, which formed in sedimentary or metamorphic rock.
The Volcano Agate sphere has unique patterns and colors due to the volcanic activity and minerals present in the lava from which the rock formed. This results in its striking appearance. It also gives it a show of colors in both natural light and UV light that reflect its fiery origins.
