Birthstones are gems that are associated with each month of the year. For the month of December, blue topaz is the birthstone. Blue topaz is a beautiful gemstone that is admired by many. It is unique compared to other birthstones because of its vibrant blue color and the way it is formed. In this article, we will explore how blue topaz is formed and what makes it unique compared to other birthstones.
Formation of Blue Topaz
Blue topaz is a silicate mineral that is formed from the mineral topaz. The process of formation begins with the dissolution of aluminum and silicon in the earth’s crust. The dissolved minerals then travel through the earth’s crust and react with other minerals, such as fluorine and hydroxide, to form topaz.
Topaz can be found in a variety of colors, including blue, pink, yellow, and brown. The blue color of topaz is caused by the presence of iron and trace elements, such as chromium and cobalt. The blue color can range from a pale blue to a deep blue, depending on the concentration of these elements.
After the topaz is formed, it undergoes a process of crystallization. The crystals are formed when the molten rock cools and solidifies. The crystals can take on a variety of shapes, such as prisms, pyramids, and rhombohedra. The shape of the crystal is determined by the arrangement of atoms in the crystal lattice.
Types of Blue Topaz
There are three main types of blue topaz: natural, irradiated, and heat-treated. Natural blue topaz is formed in nature and has a blue color due to the presence of trace elements. Irradiated blue topaz is created when colorless or pale topaz is exposed to radiation to enhance its color. Heat-treated blue topaz is created when colorless or pale topaz is heated to a high temperature to produce a blue color.
