This Volcano Agate sphere 65 mm weighs 248g. This rarer form of Agate 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.
This Volcano Agate sphere has patterns, colors and features that owe to its formation in a volcanic environment and the fluids and minerals present in the lava from which the rock formed. This results in its striking appearance. It also shows colors in both natural light and UV light that reflect its fiery origins. Its strong UV reaction, with a deep Emerald Green is particularly striking.
