1. Common Minerals
Some minerals are abundant and form the backbone of the Earth's geology. These include:
Quartz: A highly abundant mineral that comes in many varieties, including amethyst, citrine, and rose quartz. Quartz is widely used in construction, electronics, and as a gemstone(Webmineral).
Feldspar: Making up about 60% of the Earth's crust, feldspar is found in igneous, metamorphic, and sedimentary rocks. It’s used in ceramics, glassmaking, and as a building material(Minerals.net).
Calcite: Known for its white or transparent appearance, calcite is a common mineral that forms in many geological environments. It’s primarily used in construction materials like cement and as a neutralizer in the chemical industry(Amethyst Galleries).
2. Rare Minerals
While some minerals are common, others are much rarer and are often sought after by collectors and gem enthusiasts:
Benitoite: A rare blue gemstone found only in California. It’s highly prized for its deep blue color and is California’s state gemstone(Sandatlas).

Crystal Structure: Examine the shape and pattern of the mineral's crystals, as each mineral has a unique structure.
These properties can help you identify common and rare minerals alike, whether you're in the field or examining a specimen at home.
