A bit of history to understand the underground remarkably unique conditions of this particular land. About 280 to 230 million years ago magma from below the earth’s crust began pushing upward separating what we now know as Africa and the Americas.

In the small territory of what became the Uruguayan land, magma flowed reaching a layer of arid, desert-type sand creating gas filled bubbles in the underground. With all the right chemical conditions, slowly flowing lava started the process of the quartz and crystals formation. A touch of water to cool the high temperatures was needed seeping through small fissures on the geode walls. Through much research, it's now known the Guarani aquifer supplied that necessary water containing high levels of iron resulting in the most stunning purple amethysts in the world. An impressive mix of different chemicals in this area, combined with certain impurities and other minerals in the sand, resulted in the formation of amethysts of other shades and colors. The locals call these extraordinary pieces "Rainbow Amethysts".

The Uruguayan land is also strikingly abundant with stalactites found in caves. All to do with the richness of the chemical composition in this area, gifted by our planet as it formed hundreds of millions of years ago. Stalactites in this exclusive area of the world can be found as an embellishing garnish to the amethysts or just as impressive, extracted by itself. As stand alone pieces, they are delicately sliced to display their staggering beauty. Uruguay sources the most remarkable colors, shapes and impressive large sizes available in stalactites.  

The unique conditions of the earth in this region left the Uruguayan land rich with formations of these semiprecious stones of unrivaled quality. They formed 140 to 120 million years ago. Uruguay’s quality in its stones is world renowned. The country also holds the record for the largest amethyst geode ever excavated, the “Empress of Uruguay” which stands 11 feet tall and weighs 2.5 tonnes.
