Introduction to Tourmaline

Tourmaline is an inorganic compound, a complex borosilicate mineral. Tourmaline, also known as tourmaline, is mainly composed of aluminum, iron, magnesium, manganese, lithium and other elements. It is a common gem mineral, and because of its rich composition, it has formed a variety of color variants, and is loved for its unique color and energy properties. In addition, it also has unique electrical and optical properties.

Meaning of Tourmaline

Tourmaline is a powerful crystal stone, unique for its pleochroism, piezoelectricity and pyroelectricity. It symbolizes protection, purification, power, spiritual growth, health, wealth, love and creativity in different cultures and spiritual practices, and is widely used in spiritual healing, jewelry, feng shui and other fields.

Pink tourmaline represents the connection to the heart chakra, promoting love, emotional healing, and improving interpersonal relationships.

Characteristics of Tourmaline

Physical characteristics: Tourmaline contains elements such as iron, manganese, chromium, lithium, and aluminum, making its colors varied, with common colors being black, pink, green, and blue. It has a glassy luster, a hardness between 7-7.5, belongs to the trigonal system, and the crystals are columnar with stripes on the surface.

Chemical characteristics: The chemical formula of tourmaline is Na(Mg,Fe,Li,Al,Mn)₃Al₆(BO₃)₃Si₆O₁₈(OH)₄. It has good stability, but is easily corroded in strong acids and alkalis.

Other characteristics: It generates electric charges when heated and compressed, making it thermoelectric and piezoelectric. In addition, tourmaline is also rare and diverse, from the common black tourmaline to the rare Paraiba tourmaline. In particular, Paraiba tourmaline has become a precious gem with a high price due to its unique color and scarcity.

Types of Tourmaline

Classification by color: red tourmaline, green tourmaline, blue tourmaline, black tourmaline, yellow tourmaline, colorless tourmaline.

Special types: watermelon tourmaline, Paraiba tourmaline, chrome tourmaline.

Classification by composition: lithium tourmaline, magnesium tourmaline, iron tourmaline.

Other types: bicolor tourmaline, multicolor tourmaline.

Uses of Tourmaline
