How do you detect tourmaline?
Tourmaline is a valuable gemstone that is used in jewelry as well as for its unique physical and electrical properties. Detecting tourmaline can be done through a variety of methods, including visual inspection, using a gemological refractometer, conducting an electrical test or using a UV lamp.
The first and simplest method to detect tourmaline is visually inspecting a sample of the stone. Tourmaline has a unique structure and color that is easy to recognize. It typically exhibits a columnar structure with vertically arranged striations, and has a color range that includes pink, green, blue, yellow, and black.
However, this method alone is not enough to accurately determine the genuineness of the stone.
A more accurate method to detect tourmaline is to use a gemological refractometer. A refractometer measures the degree of refraction of light passing through a gemstone. Tourmaline has a high refractive index and birefringence, which are characteristics measured by the refractometer to determine if it is a genuine tourmaline.
Another approach to detecting tourmaline is by conducting an electrical test. Tourmaline has one end which is positively charged and the other end is negatively. When a voltage is applied across the crystal, it creates an electrical current, which can be measured. A genuine tourmaline gemstone will produce electricity, which can be proof of it being a real gemstone.
Lastly, the use of a UV lamp can indicate the authenticity of tourmaline. Most tourmaline gems exhibit fluorescence. When exposed to a UV lamp, a genuine tourmaline gemstone will emit colorful fluorescence that can be seen with the naked eye. However, this method is not entirely reliable as other gemstones like sapphire and spinel also exhibit similar effects.
Overall, detecting tourmaline requires a combination of these methods. The refractometer is the most accurate method, followed by electrical testing and visual inspection while the UV lamp method is a supplementary tool. By combining these methods, gemologists can accurately determine the authenticity and quality of a tourmaline gemstone.
What does real tourmaline look like?
Real tourmaline is a mineral that comes in a range of colors and may be transparent, translucent, or opaque, depending on the type. Tourmaline is a boron, aluminum, cyclosilicate, and is typically formed in granite and granitic pegmatites. It is a complex mineral with a long crystal structure, which causes it to be available in various shapes and cuts.
Moreover, the mineral has a trigonal crystal system that produces stony hexagonal tubes with vertical striations and grooves.
Tourmaline appears one distinct color, which depends on the minerals that pair with it during its formation. Some of the most common tourmaline colors are black, brown, green, pink, blue, yellow, and red, among others. Additionally, some tourmaline may change color depending on the angle at which it is viewed, which is known as pleochroism.
In some instances, it is also possible for a single crystal of tourmaline to show multiple colors at once, which is known as bicolor or tricolor tourmaline.
One of the most striking features of real tourmaline is its transparency, which ranges widely. Some varieties of tourmaline, such as the pink and green ones, are mostly transparent, while others, such as the black ones, are opaque. Furthermore, tourmaline crystals could be clear or contain inclusions that appear like polished glass or delicate fibers that seem to form a pattern vis-a-vis the crystal structure, which gives the stone its visual allure.
Real tourmaline gemstones can be identified by their complex crystalline structure, pleochroism or the capacity to show multiple colors, transparency, and a range of colors, such as green, blue, pink, and black, among others. And whether opaque or translucent, tourmaline’s unique patterns and textures make it an eye-catching and attractive gem that is valued by many.
