Tourmaline is a kind of precious stone, which contains a small amount of natural inclusions. These inclusions are impurities wrapped in mineral crystals during the formation process. The soaking of different minerals in cracks may cause tourmaline to show various colors. Tourmaline with natural inclusions is rare in the market, because the tourmaline with natural inclusions is soft, has inclusions, is not restrained enough, and is easy to scratch the surface, leading to cracking or deformation, so it is fragile.
Although tourmaline with natural inclusions has some shortcomings in appearance and hardness, if you are interested in the collection of tourmaline, you can choose it according to your personal needs and preferences. At the same time, the synthetic tourmaline is more stable and durable in appearance and hardness, and the price is more affordable. You can also consider synthetic tourmaline.
