Differences Between Natural and Synthetic Black Tourmaline
When it comes to black tourmaline, it is important to differentiate between natural and synthetic varieties. Natural black tourmaline is formed under the earth’s surface over millions of years, while synthetic black tourmaline is created in a laboratory.
One of the main differences between natural and synthetic black tourmaline is their composition. Natural black tourmaline consists of complex silicate minerals, including aluminum, iron, and sodium, which give it its characteristic black color. On the other hand, synthetic black tourmaline is typically made from crushed natural tourmaline and various resins, which are then heated and cooled to form a solid material.
Another difference is the appearance of natural and synthetic black tourmaline. Natural black tourmaline often has a rough, jagged texture with natural imperfections and inclusions. It may also have a matte or semi-glossy finish. In contrast, synthetic black tourmaline is usually smoother and more polished, with a glossy finish.
In terms of energy and metaphysical properties, natural black tourmaline is believed to have stronger and more potent energy. It is thought to be more effective in absorbing and transmuting negative energy, and providing protection against negative forces. Synthetic black tourmaline, on the other hand, is believed to have less energetic properties and may not provide the same level of protection.
When it comes to price, natural black tourmaline is usually more expensive than synthetic black tourmaline. This is because of its rarity and the time and effort it takes to mine and process natural tourmaline. Synthetic black tourmaline, on the other hand, can be produced in large quantities and at a lower cost, making it more affordable.
