Besides, they are crystal, you are losing money!

It is said that many young girls now say "playing gems" is to buy some crystal bracelets, but for the word "crystal", do you really know what crystal is? Can not listen to the word or the online store a treasure of the gemstone classification.

Gemstones are valuable, beautiful and durable. Although it is also divided into high, medium and low grades, but it is the first-class price of the first-class goods, can not be charged to raise the price, can not be self-deprecating.

Usually we have a verbal statement, like to call the crystal gemstones crystal. But those who really understand the gems still have to have a very clear concept, knowing the correct binning, categorization and value of each gems. It is a misunderstanding of many beginners to treat many high-quality semi-precious stones as crystals. Today we must clarify this concept.

Semi-precious stones

Gemstones - Premium Gemstones - Organic Gemstones

Among all gems, there are generally classified high-grade gems and semi-precious stones, and one type of organic gems.

High-grade precious stones are the "world's top five gems" of diamonds, red sapphires, emeralds and gold emeralds.

宝石

Organic gemstones are pearls, corals, beeswax and amber.

In addition to these two, there are many mid-range gemstones such as tourmaline, tanzanite, garnet, etc. The scientific name of this part of the gem is "semi-precious stones".

*Note: Semi-precious stones are not half-gems, so semi-precious stones must also be pure natural gemstones that are completely free of artificial processing.

Quartz crystal "silica" ≠ other semi-precious stones

The real crystal should belong to only one of the semi-precious stones. Mineralogy is the crystal of quartz, and the chemical composition is pure silica. Of course, if it is mixed with other trace elements or color defects, it will also have different colors, which is why amethyst, citrine, tea crystal, amethyst and other colored crystals appear; The minerals are in the interior, and may become hairy, ghost crystal, rabbit hair crystal and so on.

宝石

Crystal for the above reasons, there will be different varieties of different prices, but without exception, the bulk chemical composition and crystal formation will not change. In theory, the chemical formula and mineral crystal composition of each semi-precious stone are different, so as long as it does not conform to the crystal, it cannot be called crystal.

The general "crystal" in the eyes of the business

Quartz crystal "silica" + non-organic gemstone "semi-precious stone"

The average merchant likes to use crystals and semi-precious stones that are as transparent as crystals as "crystals". It is the wrong attitude of people who do not understand gems to see what gems are crystal.

宝石

The semi-precious stones that are most often introduced and sold by crystals as merchants include tourmaline, garnet, aquamarine, topaz, peridot, opal and so on. Anyone who knows a little about these gems knows that these gems have different chemical and mineral names, and they are far removed from the "crystal". How can they be labeled "crystal"?

For example, tourmaline is a common name for tourmaline. The surface has micro-current and thermoelectricity. If it is the same kind, how can crystals have these characteristics? Aquamarine is clearly the same as the beryl family of high-grade gemstone emeralds. Is it also the beryl family? Impossible...

宝石

So many semi-precious stones called "crystals", as long as they are understood, can understand that they are not a substance.

宝石

Why do merchants generally refer to the general semi-precious stones as "crystal"? Because there are too many varieties in semi-precious stones, in order to be more simple to classify and operate, the sellers will first have natural crystals and other semi-precious stones. These can be directly distinguished from high-grade precious stones, but the people who buy them do not understand. There are so many doorways inside, and the gems are treated as natural crystals over time.

* Hina has something to say: You see the semi-precious stones that the boss can sell as crystals. In fact, they are all of a relatively good quality. The real quality is a good semi-precious stone. They are still honestly called the variety name, and they sound taller. Selling high prices can also reflect the true value of these semi-precious stones. Therefore, in fact, some semi-precious stones are sold as crystals. Instead, they are self-sufficient, and many people mistakenly use the valuable semi-precious stones or popular semi-precious stones as ordinary crystals.
