Heat treatment is also used to improve the hue of blue apatite. Because apatite is so plentiful and inexpensive, synthetic equivalents are uncommon. Where color quality is important, such as in jewelry, only the highest-quality materials can be used.
Blue apatite is a rare mineral with an array of intense colors that depend on its chemical composition. It can be red, purple, black, yellow, or white. Although blue apatite was first discovered in 1721, it is still being found today. Some deposits contain large amounts of blue apatite while others seem to be almost completely gray even when fresh. The rarity of blue apatite leads to it being more expensive than other colored minerals.
Apatite is a general name for compounds containing calcium phosphate. Its chemical formula is Ca5(PO4)3X, where X is either 0, 1, 2, or 3.
Apatite is primarily used in the production of fertilizer; it is a phosphorus source. It is sometimes used as a gemstone. Green and blue pigments in finely split form have high covering power.
Apatite is used for making jewelry. The color of some gems comes from small amounts of other minerals, usually metals. For example, citrine is a green gem with some yellow bits added to it. But most gems are just different forms of apatite. They may be white, brown, black, or various shades of red or orange.
Apatite is used in medicine as a supplement and antacid. It helps control acid reflux disease and ulcers by neutralizing stomach acids.
Apatite has many names including: hydroxylapatite, hydrated calcium phosphate, calcium phosphate, Ca5(PO4)3X (X=hydroxide, alkoxide), beta-Ca3(PO4)2, beta-phosphate, calcaemic glass, and eggshell powder. Its chemical formula is Ca10(PO4)6(OH)2. It is often found in nature combined with silica or alumina as corundum or zeolites.
Apatite can be made in the lab too!
Blue apatite promotes the creation of new cells and assists in calcium absorption. It aids in the healing of bones and teeth, the restoration of cartilage, and the treatment of rickets, joint disorders, arthritis, and motor skills. Blue apatite can be used to relieve headaches and vertigo or dizziness. It can also be used as a calming agent for anxiety and panic attacks.
Apatites are mineral forms of phosphorus and alkaline earth metals with an overall composition of P5O12(3+), where "P" stands for phosphate. The most common form is Apatite, but it can also be white, yellow, green, red, or brown depending on its content of other elements.
People often call all forms of apatite "rock salt", but that's not correct. Only sodium phosphate (NaPO4) is called "salt of rock phosphate". Other minerals containing phosphorus such as pyrophosphate, phytic acid, and phospholipids are not considered salts because they do not contain any free sodium ions.
Apatite is found in many natural substances including tooth enamel, bones, fingernails, hair, shells, some rocks, and some foods. It can also be manufactured into beads for jewelry or paint additives.
Uses. The color comes from chromium oxide, which can be extracted with nitric acid.
Apatite occurs naturally in the form of grains or crystals in rocks. It is also found commercially. The most common source is phosphate rock, which is mined to obtain phosphoric acid for use in fertilizers. Other sources include bonelike materials called apatites that are found in some fossils and bone tissue of living organisms, such as fish scales and turtle shells.
People have been using apatite since at least 600 B.C., when Chinese scientists discovered how to extract calcium from it. The Chinese were also the first to discover its usefulness as a pigment for paint and lacquer. In the 17th century, French chemist Antoine Lavoisier established that apatite contains more oxygen than other substances. This fact led to its use today as an indicator material in blood tests to show the amount of oxygen present in the bloodstream.
In addition to fertilizer and paint, apatite is used in medicine as a supplement to treat osteoporosis.
Blue topaz is exceedingly rare in its natural state. As a result, nearly all blue topaz used in jewelry has been heated or irradiated. Heating or irradiating the stone changes the color of the stone and makes it more visible. Heating also changes the chemical composition of the stone; therefore, any jeweler who says that he can restore the color of your stone or change its color to another hue is lying.
In nature, topaz is only colored in certain locations where there are large amounts of iron present in the soil. These locations include Brazil, India, Russia, and South Africa. Other gem-quality topazes are available at much lower prices. They are colorless or have very faint colors that do not include much of a red component.
Most blue topaz that you see in jewelry stores has had some type of treatment to make it more attractive to consumers. The most common method for doing this is heating, which transforms the dull brownish orange mineral beryl into a sparkling blue gem.
Blue Apatite stimulates the throat chakra. It improves group communication and makes public speaking easier. It soothes the heart and the emotions. Blue Apatite is associated with a very high level of spiritual guidance. It can also be related to the color blue, which represents truth, heaven, and faith.
As far as its health benefits are concerned, blue apatite is used in the treatment of bone cancer, because it promotes bone growth. It can also be used for preventing osteoporosis, since it helps prevent calcium from being lost through the urine.
In addition, blue apatite is recommended for people who have problems with their voice due to its vocal hygiene properties. It increases the strength of the muscles involved in speech production without causing them to grow too big or too heavy.
Furthermore, it has been suggested that people who wear jewelry made from blue apatite have fewer cases of urinary tract infections. This is probably because of how well it fits against the skin and how easy it is to take off and put back on when you want to go out or stay in bed.
Finally, some studies suggest that wearing jewelry made from blue apatite can help reduce stress and anxiety. This is probably because it's such an attractive stone that it can give you a feeling of peace and tranquility whenever you look at it.
