This Massive Volcano Agate sphere 185mm weighs 7920g. This sphere has been shaped from rock that formed within a cavity in a volcanic environment. This formation gives it an unusual reaction to ultra-violet light. it gives it other features too that differ from more common agates that have 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 has resulted in its striking appearance. It also shows colors in both natural light and UV light that reflect its fiery origins.
