All of these whole (uncut) agate geodes are from the Salto do Jacui region in Rio Grande do Sul province in extreme southern Brazil. This particular region is known throughout the world for containing arguably the largest agate deposits on Earth. All of these agates will contain some degree of banded agate in their skins and we guarantee 90% of these agate geodes to contain a quartz or chalcedony lined interior that may also contain additional minerals such as goethite, other iron minerals, and very infrequently calcite or gypsum. Also note that some of the geodes below contain water (see note below)! All of our agates are imported directly from a mine owner in Brazil. These geodes run approximately 5-10% light to dark amethyst but this is highly dependent on the mine that the agate geodes came from.
IMPORTANT NOTE ON OPENING THE AGATE GEODES: Given the harder skinned banded agate nature of these geodes, it is strongly recommended that these geodes be cut open versus cracked open. They are more difficult and time consuming to crack open with a hammer and chisel and may be more difficult to polish given rougher edges compared to a saw cut so please keep this in mind before ordering. They do take a very good polish when cut open and are among the most popular agate to cut and polish given their banding and ability to take a good polish.
WATER FILLED GEODES: Some of the geodes below contain water! The water can be felt or heard when shook, and virtually all of these geodes will contain banded agate in their skins and a fine, drusy quartz lined hollow that is usually smoky quartz but we have also found clear, lavender, amethyst, and light pink or blue colors in these geodes in addition to various iron minerals. These are the highest quality agate geodes coming out of Brazil right now. In our experience, the water filled agate geodes hold their water for a very long time (many years) even under higher stress conditions (such as high heat) and this may indicate the water is very old inside.
