Rock crystal
Main Deposits
We find them scattered all over the planet, but it must be said that the most precious quartz crystals are those found in the mines of Brazil, without forgetting the specimens from China or the famous Herkimers from the United States.
Description and Characteristics
Rock crystal is hyaline (transparent and colourless) macrocrystalline quartz. It forms from silica-rich solutions that crystallise within cavities in igneous or metamorphic rocks, or in hydrothermal veins. Due to the absence of chemical impurities, it is perfectly colourless. It grows in hexagonal prisms terminated by pyramids and is the standard of purity in the mineral kingdom. It has been used since prehistoric times to make tools and, later, sacred and optical objects.

Did you know...?
The name ‘quartz’ derives from the Greek word ‘kristallos’, meaning ‘ice’.
The ancient Greeks believed that rock crystal was eternal ice that had frozen in such a way that it could never melt again (hence the name krystallos, meaning ice). This also gave rise to the tradition of “crystal balls” for seeing the future, due to their ability to clarify vision.
