Rough Stone Section
The specimens in this section weigh an average of One pound, unless noted otherwise. In this section we feature our Agates and Jaspers.
Agates are a cryptocrystalline variety of silica, mainly chalcedony. They are characterized by its fineness of grain and brightness of color. Although agates may be found in various kinds of rock, they are classically associated with volcanic rocks and can be common in certain metamorphic rocks. Agate was given its name by Theophrastus, a Greek philosopher and naturalist, who discovered the stone along the shore line of the river Achates which is located in present-day Sicily, sometime between the 4th and 3rd centuries BCE.
On the Mohs scale, Agate has a hardness of 6.5 - 7.
Jasper, an aggregate of microgranular quartz and/or chalcedony and other mineral phases. The name "Jasper" means "spotted or speckled stone", and is derived from Old French "jaspre" and Latin iaspidem (nom. iaspis). Jasper has a hardness of 6.5 - 7 on the Mohs scale.
Cold Mountain Thunderegg: When split open, Cold Mountain Thundereggs offer a bright
range of colors. The thundereggs can contain water banding and features red, mauve, or black
“webbing.” While technically a rhyolite due to its thunderegg nature, Cold Mountain
Thundereggs are highly silicate and filled brecciation. This material takes an exceptional polish
which makes it ideal for both cabochons and specimens. The average size ranges between
3 – 4 inches.
