Large, unique amethyst cutbase from Uruguay. With an impressive height of 23 cm and a weight of 4.52 kg, this specimen is a true eye-catcher.

Formation: Amethyst, a violet variety of quartz, forms under specific geological conditions:

  1. Magmatic activity: In volcanic regions, hot magma flows through the Earth's crust and forms cavities in the rocks.
  2. Hydrothermal solutions: Hot, mineral-rich solutions containing silicon dioxide (SiOβ‚‚) and iron fill these cavities. Iron compounds are responsible for the purple color of amethyst.
  3. Cooling and crystallization: As the solution cools, the silicon dioxide crystallizes and forms amethyst crystals. The slow cooling process allows for the growth of large, clear crystals.
  4. Calcite formation: In some cases, as in this particular piece, additional calcite crystals grow in the cavity.

Special features:

  • Beautiful and unique: Each amethyst is unique with a fascinating structure and intense violet color.
  • Calcite Points: The natural formation of calcite points adds an additional aesthetic dimension to this piece.
  • Sugary Calcite Formation: Inside you will find a rare, sugary sparkling calcite formation that beautifully reflects the light and gives the amethyst a special depth.

The fascinating formation of crystals

The formation of crystals is a fascinating process that takes place deep within the Earth over millions of years. It begins with a highly concentrated solution of minerals in rocks or liquids. Under specific conditions such as high pressure and high temperature, these minerals react and arrange themselves, forming the first crystal nuclei. Gradually, other molecules attach themselves to these nuclei, forming a crystal lattice. The composition of the minerals, the cooling rate, and environmental factors influence the size, shape, and clarity of the crystals.


During this slow crystallization, breathtaking shapes and colors emerge, giving the crystals their characteristic beauty. Rock crystals, amethysts, and rose quartz (to name a few) are the result of this impressive natural creation process. Each crystal is a unique work of art from nature, bearing the history and conditions of its formation within itself. The variety of colors and structures reflects the various geological processes that have taken place over millions of years, making each crystal a fascinating testament to the natural world.
