Blue tourmaline Crystal - Height: 20 mm - Width: 5 mm- 10 g - (1)

Blue tourmaline, also known as indicolite, is a rare and prized member of the tourmaline mineral group, renowned for its deep blue to sky-blue color range. Tourmalines are complex boron silicate minerals whose colors are influenced by trace elements such as iron and titanium in the blue varieties. This crystal specimen, modest in size, showcases the elongated prismatic form characteristic of tourmaline crystals, often with vertical striations along their length. Blue tourmaline crystals are celebrated by mineral collectors for their vibrant color and clarity, and they are also fashioned into fine gemstones for jewelry. The mineral's piezoelectric properties (ability to generate an electric charge under pressure) make it scientifically interesting, although this specimen’s primary appeal lies in its aesthetic and collector value.
