This big Volcano Agate sphere 119mm weighs 2167g. This Volcano Agate was formed in a volcanic environment. This formation gives it features that differ from more common agates, which formed in more sedate metamorphic rock.
Its unique patterns and striking appearance are due to its volcanic formation and the minerals present in the lava from which the rock formed. It also gives it a show of colours in both natural light and UV light that reflect its fiery origins.
