Aquamarine forms when magma under the Earth's crust interacts with mineral-rich rocks under mountain ranges. The magma cools as it enters fissures and crevasses of rocks called pegamites. The minerals in the pegamites heat up when they interact with the magma, forming the gemstone.Know More
Pegamites are a type of rock that is formed primarily of mineral crystals. Almost all aquamarines are formed in pegamites. Aquamarine is a type of mineral called beryl. Beryl can be many colors, but when it is blue or blue-green, it is called aquamarine. Another common gemstone with beryl composition is morganite, which is pink. The color the beryl takes depends on the minerals it interacts with. Aquamarine is a combination of beryllium and aluminum silicate.
Aquamarine can be found in many places around the world where there are mountain ranges. It is mined in Africa, India, South America, Russia and North America. The quality of aquamarine depends primarily on its color. The gem is more valuable the deeper the blue-green color. Most aquamarine jewelry has lighter-colored stones. Other rare aquamarines have a cat's-eye effect, which is a line of shimmering light that can be viewed from different angles. Unlike many gemstones, most aquamarines are flawless, making them a good choice for rings and pendants.Learn more about Precious Metals & Gems
Granite and gabbro are igneous rocks formed through the cooling and crystallization of magma in the Earth's crust. They are identified by their specific mineral content and composition.Full Answer >
The rock cycle explains the changes rocks undergo from the time they are expelled from the earth's mantle in the form of magma to the time that they return to the mantle and become magma once more. This process takes place over millions to billions of years, depending on the conditions the rocks are subject to. Weather, heat, water and pressure are all forces that affect the rock cycle.Full Answer >
Each month has at least one official birthstone, beginning with January, which is garnet, and followed by amethyst for February, aquamarine for March, diamond for April and emerald for the month of May. The birthstone for June is pearl, July is ruby, August is peridot, September is sapphire, October is opal, November is citrine, and December is blue topaz. The official list of modern birthstones was created in 1912, and has only been altered once since, in 2002, when tanzanite became the fourth birthstone to be associated with December.Full Answer >
