Geology collection

This set includes eight different quartz varieties, each with its own unique color and properties, presented in a practical box. Quartz is one of the most abundant minerals in the Earth's crust and consists of silicon and oxygen (SiO₂). Traces of other elements give quartz its wide range of colors.

Inside the box, you will find:

Milky quartz
Rock crystal
Amethyst
Citrine
Smoky quartz
Agate
Aventurine
Rose quartz

Each stone measures approximately 3–3.5 cm at its longest, and an included fact sheet provides insight into quartz's properties and uses. Did you know that quartz is used in everything from watches to the production of glass and ceramics? This set is perfect for curious minds eager to learn more about geology and mineralogy.
