Crystals and minerals are naturally occurring substances that form through geological processes and have been valued for their beauty, rarity, and metaphysical properties for millennia. They are often distinguished by their chemical composition and atomic structure.
Crystals vs. Minerals
Minerals: Naturally occurring inorganic substances with a defined chemical composition and internal crystal structure. Examples include quartz, calcite, and fluorite.
Crystals: When minerals form in specific geometric shapes due to their atomic arrangement, they are referred to as crystals. For example, quartz is a mineral that forms hexagonal crystals.
Formation
Crystals and minerals form through various natural processes:
Magmatic Processes: Minerals crystallize as magma cools, forming igneous rocks. For example, feldspar and quartz are common in granites.
Metamorphic Processes: Heat and pressure deep within the Earth can cause minerals to change form, such as graphite transforming into diamond.
Sedimentary Processes: Minerals can precipitate out of water in sedimentary environments, such as halite (rock salt) forming in evaporating lakes.
Popular Crystals and Minerals
Quartz:
One of the most common minerals on Earth, quartz comes in many varieties like clear quartz, rose quartz, and amethyst. It is used in jewelry and for its purported spiritual properties of clarity and energy amplification.
Amethyst:
A purple variety of quartz, amethyst is often associated with spiritual growth, protection, and healing.
Tiger's Eye:
A chatoyant gemstone known for its golden to brown stripes, tigerโs eye is believed to bring balance, confidence, and courage.
