Sapphire is blue, so green gems are called emeralds, what a ghost? Some "urban legends" can't be tolerated when they reach the end of the world. When it comes to the name of the gemstones, in order to correct everyone's three views, there are several common sayings today that really want to correct. See how many of you have believed?
Sapphire is blue, so green gems are called emeralds.
Rumors: You can name them directly with "color + gems". Only rubies and sapphires, all other gems have their own professional mineral names and commercial names. You can't scream.
Interpretation: Among the world's top five gems, rubies and sapphires are the most well-known in addition to diamonds. The imperial powers of ancient and modern China and foreign countries love to collect them, and the value is also well known.
Moreover, these two kinds of gems belong to the same kind of minerals as "corundum", and only in the gem-grade corundum, the color is distinguished. So in the strict sense, the name "color + gem" is only found in gem-quality corundum.
Jade is called jade!
Rumors: In a broad sense, "Jade" is the collective name of Hetian jade, the name of nephrite, and the jadeite of the scientific name jadeite. In fact, the "Jade" that people who know how to say refers to Hetian jade, which is called "Jade".
Interpretation: Chinese people especially like to play jade, so naturally think that this category of gemstones should contain jade. However, the Chinese themselves often fail to distinguish themselves. Chalcedony, agate, Hetian jade, and jadeite are often referred to as "jade". The value of this is quite different.
The value of Hetian jade and jadeite is the highest among them, but it is not a kind of thing. In order to distinguish, jade and jadeites generally refer to jade and jade as "Jade", and green and hydrated as "Jade".
The world's top five precious stones are all very expensive
Rumors: One of the world's top five precious stones is called "Gold Emerald". This kind of gemstone can be sheltered because some of them have cat eye effect or color change effect.
Interpretation: Gold emerald is famous for its cat's eye effect, so that "cat's eye" has become the exclusive name for the golden emerald with cat's eye effect. Other gemstones with cat's eye effect are named after "cat's eye + gem name". For example, cat's eye tourmaline.
Cat's eye tourmaline
If there is no special optical effect, these golden emeralds are not popular with the public, and the color is not pleasing, but if you have the cat eye effect or the color change effect, the value will double immediately.
Only the ruby ​​made in Myanmar can become a pigeon red
Rumors: As long as a certain chromatographic range is reached and the fluorescence intensity is recognized, whether it is made in Myanmar or Mozambique, it can be considered as pigeon blood red.
Interpretation: Many people buy rubies and they are superstitious, and the pigeons are bloody and superstitious. Although the blood red of the Mogo pigeon is old, it is not bad, but because of long-term mining, the output and average quality have declined. The red treasure deposit discovered in Mozambique in recent times is a new deposit, and its output is relatively large. Among them, there are many high-quality red treasures that can be selected.
"Dove Blood Red" is a top-grade ruby ​​variety with a corresponding set of identification standards. As long as it meets its standard color gamut range and fluorescence intensity, the ruby ​​can be issued regardless of where the ruby ​​is produced.
The gem that needs water is to soak
Rumors: Water conservation means that some jade-type gemstones need to be replenished, but there is a way to replenish water, and it is not a fish.
Interpretation: Generally, gemstone hydration is to avoid damage caused by long-term exposure. The usual method is to rinse regularly with water. Among the jade-like gemstones, turquoise, sea stones, and opal are all needed, but the longest is no more than half an hour. Do not soak for a long time.
Many gems have a low hardness and a large gap. After soaking in water, it is easier to disintegrate and crack, so even after rinsing, it needs to be wiped clean with a soft cloth. Long-term soaking in water is more likely to cause the deposition of minerals such as calcium in the water, leaving the surface of the gemstone tarnished and finally "necrotic".
Radiation-treated gemstones can cause cancer!
Rumors: The particles used for irradiation and color change are only one of the radionuclides, and the amount is very low. When the jewelry is at hand, the radioactivity has already been exhausted.
Interpretation: There are generally several ways to change the color of the irradiation. The most common way is to use the high-speed particles of the ray to impact the internal structure of the gemstone, forcibly causing the color defect of the structure to produce color or strengthen the color. Although it is a ray, there is no need to worry about it. The amount of radiation used for color change is almost the same as that of the common items such as power stations, mobile phones, and televisions.
The radioactive material left on the gemstone will be dissipated for up to a year and a half, and a piece of jewelry will change from the original color to the processing and polishing, and then the design will be inserted, and the final time limit will be exceeded when the final sale is made. So don't talk about carcinogenicity, but it doesn't have any effect at all. Only high-end collectors sometimes pursue pure, natural, non-colored gems for perfection.
Zircon
To say that there is radiation, some natural mineral stones do contain radiation harmful to the human body, such as low-type zircon, which is rich in radioactive elements and thus has more serious radiation, which can cause damage to the human body. Because the color of low-type zirconium is very beautiful, there are also a few businesses that operate, so be careful.
