Most of the crystals are colorless and transparent. Además, there are pink hibiscus stone, amatista morada, yellow topaz, brown citrine (also called smoke crystal) and black smoky crystal. Although the price of natural crystal has been very low, since the invention of artificial crystal technology, its output has increased rapidly and the price has become lower and lower.
The more special thing is: the value of natural products of colorless transparent crystal is lower than that of man-made ones! The price of natural products is very low, but because there are some impurities or blemishes inside, although it is not a hindrance to the manufacture of jewelry such as necklace beads, it cannot be used for advanced technology applications, such as the manufacture of quartz watch movements and high-end watches. Advanced technology must use artificial colorless crystal without impurities and blemishes. Due to the high production cost, the market price of artificial colorless crystal is more expensive than natural crystal, and it is generally not used as a raw material for jewelry.
Natural colored crystals are much more expensive than colorless crystals. Artificially produced colored crystals, such as amethyst and topaz, are cheaper than natural ones. Además, there are no green and blue natural crystals, but artificial crystals can be produced. Por lo tanto, any jewelry that sees green or blue crystals must be artificial. Due to the high cost, their prices are more expensive than amethyst and topaz.
Regardless of the fact that natural crystals and artificial crystals are not expensive, it is difficult to distinguish between them. Even gem experts or testing agencies sometimes cannot identify them with simple and rapid methods. If accurate identification is necessary, sometimes large-scale identification instruments are used. The identification fee of such instruments is relatively high, but crystals are worthless gems. Sometimes the price of a ring or even a necklace is not worth the identification fee. Sky crystal and man-made crystal are not different in nature. They are only produced in the natural environment of nature, while the latter is produced by artificial devices. Al mismo tiempo, the price difference between the two is not too big, so it is not necessary. To distinguish them.
