Trancas Geodes Blue Chalcedony Crystal Quartz
Trancas Geodes Blue Chalcedony Crystal Quartz Scepters
Trancas geodes with blue chalcedony can contain scepters, a clear to slightly sky blue color, light smoky quartz, and a clear to cloudy calcite lining. About 85% of the Trancas geodes fluoresce a bright green (under shortwave ultraviolet light which is caused by very small trace amounts of uranium – not enough to hurt life).
Some of the Trancas contain calcite, fluorite or additional quartz growths like scepters (which are worm-like structures), banded/circular quartz, and coated agate.
In addition to their fluorescent abilities, these geodes are highly sought for their quartz scepter growths.
