When most people hear the word "apatite," they likely think of the mineral that makes up our teeth and bones. While it's true that apatite is a crucial component of these structures, there's more to this mineral than meets the eye. In fact, apatite is a diverse group of minerals with a wide range of uses and properties, from gemstones to fertilisers.
The Chemistry And Biology Of Apatite.
Let's start with the basics. Apatite is a calcium phosphate mineral with the chemical formula Ca5(PO4)3(F,Cl,OH) - looks very confusing! It comes in a variety of colours including blue, green, yellow, brown and even colourless. Its name comes from the Greek word "apate," meaning deceit because it was often mistaken for other minerals (due to its varying colours).
One of the most interesting things about apatite is its role in our bodies. As mentioned, apatite makes up about 70% of the mineral content of our teeth and bones. It provides the strength and rigidity that allow these structures to support our bodies and protect our organs. Apatite is involved in the regulation of our metabolism, and the storage and release of calcium and phosphorus.
But apatite isn't just important for humans. It's also a critical component of many other organisms including fish, birds and reptiles. In fact, some animals use apatite to create biominerals which are minerals that are formed within living organisms. These biominerals can serve a variety of functions, from providing structural support to aiding in digestion.
Other Applications Of Apatite.
Outside of biology, apatite has many other uses as well. It's a common mineral in igneous rocks and is often used to date the age of these rocks through radiometric dating techniques. Apatite is also a valuable mineral in the mining industry because it can contain significant amounts of rare earth elements which are essential for many modern technologies.
The Beauty Of Apatite As A Gemstone.
Perhaps one of the most fascinating aspects of apatite is its use as a gemstone. Apatite is a relatively soft mineral with a hardness of 5 on the Mohs scale. This makes it a popular choice for jewellery because it can be easily cut and polished into a variety of shapes and sizes. Apatite gemstones come in a range of colours, from a vibrant blue-green to a soft yellow, and can be found in many parts of the world including Brazil, Mexico and Madagascar.
Apatite's use as a gemstone is not just limited to its beauty. Some people believe that apatite has metaphysical properties that can aid in emotional healing, creativity and self-expression. While there's no scientific evidence to support these claims, it's clear that apatite has captured the imagination of many people throughout history.
Apatite and Sterling Silver Earrings.
Apatite is also used in the production of sterling silver earrings because it’s a popular choice for use as a gemstone in jewellery. It is often found in pendants, earrings and rings. Apatite is often set in sterling silver which complements the stone's vibrant colours and adds a touch of shine and elegance to the piece.But the benefits of apatite and sterling silver earrings go beyond just their good looks. Sterling silver is a durable, long-lasting metal that won't corrode or fade over time. This means that your apatite earrings will stay looking beautiful for years to come. And because sterling silver is a hypoallergenic metal, it's a great choice for those with sensitive skin who may have trouble wearing other types of earrings.
Overall, apatite is a beautiful and versatile gemstone that is popular for use in a wide range of jewellery styles and other applications. Its vibrant colours and durable nature make it a perfect choice for use in sterling silver earrings and other types of jewellery. Whether you are looking for a statement piece or a subtle and elegant accessory, apatite is a gemstone that is sure to make a stunning addition to any jewellery collection.
