Is tourmaline a type of crystal?

Tourmaline is also known as tourmaline, and its English name Tourmaline means "mixed gemstone". Although it is a little similar to crystal in color, tourmaline is not crystal, and the price is completely different.

The composition of tourmaline and crystal is different. From the perspective of chemical composition, tourmaline is a complex silicate, while crystal is a single silicon crystal. The two are completely different. Therefore, tourmaline and crystal are two completely different substances. The density of crystal is smaller than that of tourmaline. And the internal structure is completely different. Crystal is a single crystal, and tourmaline is a trigonal crystal. So strictly speaking, tourmaline is not considered a crystal.

What color tourmaline is rare?

Red and blue are more valuable in tourmaline, while yellow and green are more common. When choosing tourmaline jewelry, red, blue and green are good, and the colors should be uniform and bright; in necklaces and bracelets, rich colors are best. If you have to take pictures in an order, it is probably blue>red>green>yellow.

In addition, the more transparent the tourmaline is, the better the quality is. It should not have obvious fog or opacity.

Tourmaline is very brittle and prone to cracks and a large number of inclusions. The presence of these defects will affect the transparency, color and fire of the seal. The fewer internal impurities and defects, the higher the price.

Will tourmaline become more transparent the more you wear it?

Yes.

Since tourmaline will come into contact with human sweat when worn for a long time, the acid and alkali in the sweat will penetrate into it through the gaps in the tourmaline, thus causing a series of chemical reactions, making the water head of the tourmaline become richer and richer, and the tourmaline become more and more transparent.

The longer you wear your tourmaline, the more transparent it becomes, mainly because the tourmaline is polished and waxed.
