How noble are tourmalines and crystals, and are tourmalines crystals

Tourmaline crystals are not very noble.

Tourmaline is not crystal. Tourmaline is a boron-bearing cyclic borosilicate mineral containing aluminum, iron, magnesium, sodium, lithium or potassium.

In the classification of gemstones, tourmaline is a semi-precious stone and comes in a variety of colors. Early Sri Lanka.

Transparent high-quality tourmaline was brought to Europe by the Dutch East India Company to satisfy curiosities and the gemstone market, and at the time iron-tourmaline (black tourmaline) and tourmaline were not considered the same mineral.

Crystal is a rare mineral, a type of gemstone, a quartz crystal, which belongs to the quartz family in mineralogy. The main chemical component is silica.

SiO2), when pure, it is a colorless and transparent crystal, when it contains trace elements.

It is purple, yellow, brown, etc. The hardness is 7, brittle, and the melting point is 1713. Mineral containing associated inclusions is called inclusion crystal, such as hair crystal, green ghost, etc., and the inner inclusions are rutile, tourmaline, actinolite, mica, chlorite, etc.

Tourmaline is not crystal, the main component of crystal is silica, whereas tourmaline is a borosilicate crystal, which is composed of elements such as magnesium, sodium, lithium, chromium, copper, potassium, etc. Tourmaline is a tourmaline, its color is rose red, pink, blue and green, long-term wear tourmaline can supplement the lack of metal elements in the human body, promote human health.

Tourmaline is not crystal Tourmaline belongs to tourmaline, it is not crystal, the composition of crystal is silica, and tourmaline is a borosilicate crystal, composed of magnesium, sodium, lithium, chromium, copper, potassium and other elements. Tourmalines are graded to gem quality, and high-quality tourmalines are rarer than diamonds.

Tourmaline comes in many colors, usually rosy and pink. Blue and green, the tourmaline of our state is mainly produced in Xinjiang and Yunnan. Tourmaline is chemically stable, and its color changes with the change of viewing angle, and is generally used to make jewelry to wear.

If tourmaline is worn for a long time, tourmaline can replenish the missing metal elements for the human body, thereby promoting high health of the human body. Tourmaline, like crystal, contains magnetic field energy, which can improve people's bad mood, and can also increase their own charm and attract the attention of the opposite sex.

1. Most of the crystal is pure color, and tourmaline is multi-colored.

2. The specific importance of tourmaline is greater than that of crystal, and the weight can be judged from the feel, and the gloss can be observed with the naked eye. Imitation shed.

3. The chemical composition of the two is different, tourmaline is a complex silicate, and crystal is a colorless and transparent large quartz crystal mineral. The main chemical component of crystal is silica, when the silica crystallization is perfect, it is crystal, silica gelatinization and dehydration is agate, silica water-containing colloids become opal after solidification, silica grains are less than a few microns, it is composed of chalcedony, flint, secondary quartzite.

The differences between tourmaline and crystal are as follows:

First, the difference in composition.

Tourmaline is a borosilicate crystal, and crystal is a colorless, transparent quartz crystal mineral, the main component of which is silica.

Second, the difference in grades.

Tourmaline and crystal are very similar in appearance, many people can't distinguish between them, although they both belong to gemstones, but tourmaline belongs to the high-end gemstones in the jewelry industry, and crystals belong to general gemstones.

3. Differences in color.

Tourmaline has cochroism, and there are multiple color combinations on a tourmaline, but crystals are generally monochromatic, and there will be no color mixing. Moreover, the color of tourmaline is much richer than that of crystal, and if it is subdivided, it can reach about 15 kinds.

Tourmaline purchase tips:

1. Weight. The greater the density of tourmaline, the greater its weight will be, so when buying tourmaline, you should first check the weight, and the tourmaline that feels particularly pressed is the best tourmaline.

2. Color and luster.

Tourmaline is a type of gemstone, and most gemstones will have a treasure light, and the same is true for tourmaline, a high-quality tourmaline treasure leaks out, and it looks very dazzling.

3. See if there are flaws.

A good quality tourmaline has no blemishes on the surface or inside and can be seen very clearly through the light, while a bad tourmaline is the opposite.

1. The chemical composition is different.

The main chemical component of crystal is silica, and when silica crystallizes perfectly, it is crystal; After silica gelatinization and dehydration, it is agate; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, chalcedony, flint, and secondary quartzite are formed.

The chemical composition of tourmaline is complex, and there is no synthetic tourmaline yet.

2. The color is different.

Crystals are colorless, light to dark purple, light yellow, medium to dark yellow, light to dark brown, brown, green to yellow-green, light to medium pink.

Tourmaline is the most abundant in color of all types of gemstones, and in the same tourmaline crystal, due to the uneven distribution of components, it often leads to color changes, along the tourmaline there are types such as bicolor tourmaline, multicolor tourmaline or infrared green watermelon tourmaline.

3. The performance is different.

Tourmaline is thermoelectric, and when exposed to heat, friction, or the sun, its appearance will have an electric charge. These charges are attractive to the opposite charge in the air, and can absorb dust, paper scraps, etc. in the air with the opposite charge. This is a property unique to tourmaline.

Crystals are piezoelectric, and crystal crystals generate electric charges when they are subjected to pressure; Conversely, when subjected to voltage, the crystal will vibrate at a very high frequency. Crystals have the ability to transfer pressure and charge to each other, which is called piezoelectricity.

Tourmaline is a gemstone.

The English name tourmaline is derived from the Old Sinhalese (Ceylonese) word turmali, which means "mixed gemstone". Tourmaline has a complex composition and a complex and varied color. The international jewelry industry basically divides the commercial varieties of tourmaline according to color, and the more intense the color, the higher the value.

When purchasing, you should pay attention to color, transparency and purity.

At present, many unprofessional merchants in the market sell some low-grade tourmaline and crystal together, and introduce tourmaline to customers as a kind of crystal. Many people think that tourmaline is a kind of crystal that is not high. Actually, this is not true, tourmaline and crystal are two different minerals at all.

In the jewelry world, tourmaline is a mid-to-high-end gemstone, and high-quality tourmaline is rarer than diamonds. Crystals, on the other hand, are ordinary gemstones.

Tourmaline is the name of tourmaline, which is a type of tourmaline family that has reached the jewelry level, is a borosilicate crystal, containing aluminum, iron, magnesium, sodium, lithium, potassium and other chemical elements, showing a variety of colors.
