Uruguay
South America
From the basalt beds of the Artigas Department to the hidden veins of agate and amethyst, Uruguay is a quiet powerhouse in the world of gemstones. Known for its deep-violet geodes, rich agates and quartz clusters, every piece from this land carries the light of ancient volcanics and time.
fun fact
A naturally heart-shaped amethyst geode was discovered in the Santa Rosa mine (Artigas), creating a viral mineral moment among collectors.
MINING REGIONS
Los Catalanes District (Artigas)
Recognized as a Geological Heritage Site, this is Uruguay’s most famous mining area and the source of many of the world’s finest amethyst and agate geodes. Within the district, Catalán Grande yields both amethyst and agate, while La Bolsa produces intensely colored, high-quality amethyst crystals.
Santa Rosa & San Eugenio Mines
Smaller but historic quarries known for unique formations — including the discovery of a famous heart-shaped amethyst geode. These localities contribute to Uruguay’s reputation for rare, museum-grade specimens.
Rivera Region
Located near the Brazilian border, Rivera hosts smaller basaltic veins producing clear quartz and occasional amethyst pockets. Its proximity to Artigas makes it part of the same volcanic belt that birthed Uruguay’s signature purple geodes.

Founder’s Note
Collected with Intention
Every crystal begins as an encounter shaped by time and human touch. I personally source each piece, working closely with miners and artisans who handle them with care.
As a photographer and lifelong lover of design, I’m drawn to light, color, and form, the same elements that make crystals feel like natural works of art.
Each piece is photographed in natural light to honor its true texture and energy, a quiet balance of beauty, material, and meaning.

Most are from the Artigas Department in northern Uruguay — particularly the Los Catalanes mining district, known for world-class amethyst geodes and agates.
The deep, rich violet hue of Uruguay amethyst is notable for its uniform saturation and clarity, often surpassing comparable stones in color intensity.
Rinse with cool water and let air dry. Avoid prolonged direct sunlight to preserve the deep purple color of the amethyst geodes.
Gently rinse under cool running water and allow to air dry. Avoid using harsh chemicals or saltwater, especially for softer minerals like selenite or malachite. Regular cleansing helps restore their natural brilliance.
Amethyst geodes (deep violet quartz) are signature. You’ll also commonly see agate, chalcedony and clear quartz clusters from the same volcanic flows.
These geodes developed in basaltic lava flows (part of the Paraná-Etendeka large igneous province). Groundwater entered cavities in the basalt, and over millions of years, silica-rich fluids crystallized quartz then amethyst.
