75 Natural double terminated pendants

Double enders of rock crystal have clear points at both ends. Some stones are naturally formed, a double terminated distributes or absorbs energy simultaneously at both ends and channels her in two directions at once. A stone with a double ended integrates mind and matter and can form a bridge between two energy points. These crystals are useful in healing, because they absorb negative energy and break old patterns. You can also use them to integrate previously blocked parts of the self. If doubl Leinders be placed on the third eye, they can strengthen telepathy.

Tourmaline (quartz) is a group of minerals, all cyclo silicates. The minerals in this group share a characteristic chemical formula: AX3Y6 (BO3) 3 Si6O18 (O, OH, F) 4. The A may contain calcium or sodium. The X can consist of aluminum, iron, lithium or magnesium. The Y is typically aluminum, but may also be chromium or iron. At the position of A may be some potassium, manganese can be in X and vanadium can be found in Y, but these elements are not common in the formulas of the tourmaline group. Tourmaline is found in pegmatites, metamorfieten, magma tits and alluvial deposits. Although tourmaline was known already in antiquity in the Mediterranean, he was only in 1703 from Sri Lanka by the Dutch introduced in Western Europe. They named the new gem of a Sinhalese word "Turmali" which means "stone of mixed colors". If gemstones were used traditionally Rubel left - they were by artists like talisman, because they would increase creativity of artists. Tourmaline have certain unique properties. They are piezo-electric, which means that if a crystal is heated or compressed, different electric charges are formed at the both ends of the crystal. This creates an electrical potential. If an external electrical potential is carried out on the crystal, it vibrates. The minerals are pleochroïsch, which means that the crystal darker in color is viewed along the longest axis of the crystal, considering than perpendicular to that axis. The four best-known and most abundant tourmaline minerals have different colors and transparencies. ELBAITE is transparent and valuable gemstone. Schorl, which is rich in iron, is the most abundant mineral in the tourmaline group, and is black and opaque. It is mainly formed in pegmatites, the extreme slow cooling gangues of a magma. The other two tourmalines are regularly encountered draviet and uviet. Draviet is usually brown translucent and may be very large. Uviet green translucent to opaque. Tourmaline is found in the sands of Dutch Quaternary river sediments. Among others it is a characteristic component of Maas Zanden. In the heavy-mineral analysis as in the Netherlands at the Geological Survey during the second half of the twentieth century took place the mineral is classified in the so-called stable group

The garnet group comprises minerals of a cubic crystal system, and crystals in the form of rhombic dodecahedrons and trapezoëders. The nesosilicaten are of the general formula A3B2 (SiO4) 3. Shells may contain the chemical elements calcium, magnesium, aluminum, Iron2 +, + ijzer3, chromium, manganese and titanium. Grenades show no cleavage. The hardness is from 6.5 to 7.5, and shells can be transparent to opaque. The name "garnet" comes from the Latin word granatus, and refers to malum garanatum (pomegranate) is a plant with red seeds resembling found on many garnet crystals. Garnets are contrary to what is commonly believed, and the name suggests, is not always red, but may purple, red, orange, yellow, green, brown, black or colorless. In 1998 Bekily, Madagascar, for the first time found a blue-pink garnet. This variant is considered very rare. The six most common variants are pyrope, almandine, spessartiet, grossular, uvarovite and andra diet. These occur in two solid solution series: 1.De pyralspiet Group: pyrope-almandine-spessartiet 2.De ugrandiet group: uvarovite-grossular-andra diet. Grenades are very common in the lower crust and mantle, thus playing a major role in chemical understanding of the Earth. The grenade is one of the "nine gems" in Thai Order of the Nine Gems.
