This Volcano Agate sphere is 63mm in diameter. It weighs 362g. This rock formed within a cavity in a volcanic environment. This gives it some features that differ from other 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. Its strong UV reaction is particularly striking.
