What are the misunderstandings in choosing tourmaline?

Myth 1: blindly pursuing the perfection of tourmaline, there is no room for any flaws.

Consumers are cautious when choosing tourmaline, fearing that there are some impurities, ice cracks and even tiny cracks inside tourmaline. In fact, the real natural tourmaline will also have some flaws, and the fly in the ointment is the real charm of tourmaline.

Myth 2: tourmaline is hard and not afraid of breaking.

In fact, this is a very big misunderstanding. The hardness of tourmaline is about 7~7.5, but it does not mean that tourmaline is not afraid of falling. The hardness of tourmaline is determined by its scratch resistance and corrosion resistance, and the key factor whether it is easy to crack is its toughness. The higher the hardness of tourmaline, the smaller the toughness, so it is easy to break.

Myth 3: I think tourmaline is expensive and can't afford it.

In fact, tourmaline is classified as a diamond. There are three grades of high school and low school, and the price difference is also great. Therefore, when choosing tourmaline, you can choose tourmaline according to your actual economic ability.

Myth 4: Buy high-grade tourmaline at a low price.

Everyone has the psychology of being greedy for petty gain and cheap. It is impossible to buy high-grade tourmaline at a low price. Some sellers will take advantage of consumers' psychology to sell artificial tourmaline to consumers at a low price. Therefore, when buying tourmaline, you must buy a reputable seller supported by a professional jewelry appraisal agency, and at the same time you must be able to issue detailed invoices. In this way, once the problem of cheating is found, there is a basis. Reference: cnartn.org/8/5284.html
