![]() This crystal is said to have the ability to boost the male and female reproductive organs, putting them in good condition for reproduction. The crystal is formed with hematite and water. Tangerine quartz comes from the Santinho mine in Minas Gerais, Brazil's mining capital, and in Madagascar. Quartz sand is used in producing fiberglass, container glass, flat plate glass, and specialty glass. Quartz crystals are used in creating radios, transistors, microphones, digital watches, computer chips, and electric guitars. ![]() Today, the mineral remains to be an indispensable component in creating electronic devices due to its ability to convert electrical energy into mechanical energy. In ancient Egypt, the mineral was an important material in making beads, amulets, impression seals, and various jewelry pieces. ![]() They may have also used it as a stamp for producing written impressions in clay. The Sumerians fashioned quartz into cylinder seals and ring seals. The use of quartz traces back to ancient times. The name quartz comes from the old German word querkluftertz meaning cross-vein ore. The name was first used in 1530 by Georgius Agricola, the father of mineralogy.Īncient Greeks and Romans referred to quartz crystals as krustallos meaning ice. They believed that the mineral was ice that never melted because it was created by the gods themselves. Tangerine quartz was named after its colour which can vary from red to orange. It easily forms rounded or shell-like conchoidal fractures when subjected to impact This is why quartz crystals naturally have marks or grooves on their surface. The crystal may be durable but it's also very brittle. Unlike other minerals that dissolve in weaker acids, quartz is only soluble in hydrofluoric acid. It remains very stable even when exposed to extreme temperatures and harsh chemicals. Quartz has a Mohs hardness rating of 7 making it a highly durable mineral. Tangerine quartz specimens can be light yellow to a deep rusty orange (almost the colour red). As it precipitates, hematite creates a rusty coating inside or on the surface of the clear quartz crystal. What gives the crystal its red to orange colour? This colouration is the result of the mineral hematite being encrusted in the quartz crystal.Īs an iron stone, hematite rusts when combined with water. Naturally occurring tangerine quartz is a silicon dioxide mineral and a variety of quartz. The Physical Properties of Tangerine Quartz
