This kind of synthetic gemstone that has been used as diamond substitutes since 1976, referred to as CZ (full name Cubic Zirconia). The cost is low, and it is very close to the diamond in optics. It has high refractive index (2.15), high -color dispersion (0.060, diamonds 0.044) and high density.

Because the Chinese name of the synthetic cube oxidation is relatively mouth, most merchants simplify its name and call it “vermiculite”, but in fact this title is irregular.

Synthetic cubic oxidation is not only used to imitate white diamonds, but also can make various colors. Advanced CZ also often uses CVD diamond plastic to increase luster.

why?

Add a small knowledge here:

There are three types of vermiculite, which are divided into high, medium and low type according to the degree of crystallization

Essence Gem -class vermiculite is basically high -type vermiculite. Low -type vermiculite is approximately amylum. Even when it is gemyt, it is usually turbid and there are a lot of cloud -like buns.

Most of the low -type vermiculite is dark green, so people think that the green vermiculite thinks it is a low -type vermiculite, and it has entered a misunderstanding.

In fact, the green vermiculite is not all low -type vermiculite. The pure and bright, high -net green high -type vermiculite is a unique color in the vermiculite family, and it is also the heart of the gem collection clip.

Radiovisal radiation

Many people have heard of rumors of radiation in vermiculite, but in fact

Each of us lives in radiation.

亮度火彩堪比钻石,被名字耽误了的“背锅美人儿”:天然锆石

According to the effect, radiation can be divided into two types: ionizing radiation and non -electrical ionization radiation. The radiation of people’s discussions, in fact, it should be said that it should be

ionizing radiation

And the radiation generated by common mobile phones, microwave ovens, and infrared rays in our lives, and the radiation of common gems that everyone worry about, belongs to low -energy electromagnetic radiation, and have strong ultraviolet radiation when you are in the sun.

Natural vermiculite contains radioactive elements: uranium (U) and 钍 (TH), which will produce very, very slight ionizing radiation, but will not pose a threat to health.

Depending on the degree of destruction of radioactive elements to internal structure, vermiculite can be divided into high -type vermiculite, medium vermiculite and low -type vermiculite. The use of jewelry is generally radioactive.

Moreover, before the listing, it will be tested to ensure that the radioactive activity is lower than the residual radioactives in the national radiation protection regulations to be sold in order to be sold.

Wearing a pigeon egg size, the radioactive activity is lower than the exemption value stipulated by the state, and the radiation dose cumulative for one year is equivalent to the effective dose of your 10 -hour aircraft finger.

Wearing and maintenance of natural vermiculite jewelry

亮度火彩堪比钻石,被名字耽误了的“背锅美人儿”:天然锆石

Although the vermiculite is strong, high -colored, rich in color, and good hardness, there is a fatal weakness -crispy.

The vermiculite is very crispy, and a slightly knocking out will drop a corner or even the overall division. In addition, the face edge of vermiculite is easily damaged, and it will even be damaged due to the friction with the wrapped paper. This phenomenon is often called “paper erosion effect”.

Therefore, it is necessary to wrap the floppy paper when packaging is packaged; the vermiculite jewelry must avoid bumps and impacts in daily wear, and place it alone when not worn. Do not throw a bunch of other jewelry.

Mr. J said:

The rich color, dazzling, pure and translucent natural vermiculite is a beautiful colorful gemstone that is “misunderstood” due to the name. Compared with the horizontal direction of gems similar to physical properties, its price is also very reasonable. For gem collection enthusiasts, gathering different colors is a pleasant process.
