50 mm Strawberry Quartz points polished from China.

Quartz and quartz comes from the German "strawberries" refers to the pink color with dark dots of the stone. Good for the heart chakra. Strawberry Quartz is a pink speckled, slightly translucent stone belonging to the macro-crystalline quartz family. Operation of Quartz gemstones Strawberries: Strawberries Quartz promotes love, enjoy small things, humor and joy and is therefore good against inner turmoil and tensions. The stone helps empower positive affirmations and has a positive effect on the heart.

Quartz is a form of silicon dioxide, SiO2, and is one of the most common minerals of the earth's crust. It represents more than 12% of the volume of the crust of the earth (inter alia, in granite, sand). Quartz has two modifications: α-quartz is trigonal, β-quartz (a high-temperature form) is hexagonal. In addition, silicon dioxide is still in many other structures such as α- and β-cristobalite, keatiet, tridymite, coesite, stishovite, melangoflogiet and lechatelieriet. Although quartz is composed of silicon dioxide, it is often considered to be the tectosilicates. The reason for this is that quartz is a network of SiO4 tetrahedra. In which each oxygen atom is shared between two silicon atoms. Individual SiO2 molecules come only with gaseous silicon dioxide for. Quartz may be of high purity, such as rock crystal, but often contains impurities. These impurities can include ions, which are incorporated during growth of the crystal in the crystal lattice. Quartz crystals can contain between 13 and 15,000 ppm Al3 +, of between 9 and 1400 ppm of Na +, is between 3 and 300 ppm of K + and traces Fe3 +, Ti4 +, P5 +, H +, and Li +. The aluminum and iron in combination with ionizing radiation are responsible for the color of a quarter of a number of varieties. Further, quartz crystals grow on other minerals, such as at around Rutielkwarts is the case. Quartz crystals can form both large and form microscopic aggregates. The largest quartz crystals occur in Lost Farm in Namibia. Quartz crystals up to 20 meters, and possibly 50 meters, and up to 2 meters dolomietkristallen come here for. When quartz is melted, it forms a glass when cooled rapidly, many times, because the crystallization process takes quite a lot of time. Quartz is a piezoelectric material, and the vibrations which can induce in the lattice of the crystal are used in electronic equipment such as quartz clocks and radios.
