Agate is a mineral formed by tiny little layers of cryptocrystalline quartz, chalcedony and opal. The product represents a rough piece of agate cut in half; the front side has been polished and the bottom side has been cut and smoothed out in order to make stone stand solidly. Thanks to this treatment, the unique patterns and regular banded lines typical for this agate can stand out. Some varieties also have tiny cavities filled with little crystals of quartz. Our agates are from large mines in the state of Rio Grande do Sul in Brazil.

The intensity of agate patterns is often boosted by dyeing. Agates are porous and have good ability to absorb liquids. During the dyeing process, the liquid soaks into individual layers of agate according to the level of their porosity. The blue-green colour is a result of chromium oxides’ absorption and heat-treatment. The original technology of dyeing is usually replaced with cool-dye, resulting in a blue-green shade, also known as teal.

Use: Agate with cut base can be a charming interior decoration or an original paperweight.
