Faceted Rainbow Rock Crystal – 5 cm, 84 g, diamond cut, extra clear from Brazil

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.
