Question 2: Is zircon worth it? How to sell it in the market! There are two kinds of natural zircon and synthetic zircon. The price of zircon is very low, except for exquisite workmanship, which is thousands of dollars, generally ranging from tens of dollars to 300 yuan. Zircon is a silicate mineral and the main ore for refining zirconium. Zircon widely exists in acidic igneous rocks, metamorphic rocks and other sediments. The chemical properties of zircon are very stable, so gem-grade zircon can also be seen in river gravel. There are many kinds of zircon, and different zircon will have different colors, such as red, yellow, orange, brown, green or colorless and transparent. The cut gem-grade zircon looks like a diamond. Zircon used to be called zircon or hyacinthus orientalis. Zircon can withstand high temperature above 3000℃, so it can be used as thermal insulation material for spacecraft.
Zircon, also known as zircon, is the birthstone of December, symbolizing success. (Birthday stone in December, turquoise and lapis lazuli) Its English name is zircon. Zircon is a mineral name, which used to be called zircon and hyacinthus orientalis, and transparent zircon gem.
Chemical composition of zircon: zirconium silicate; The chemical composition is Zr[SiO4], and the crystal belongs to the island structure silicate mineral of tetragonal system. Crystals are short columns, usually square columns, square bipyramids or complex square bipyramids. Zircon has a variety of colors, such as colorless, purple, tan, light yellow, reddish, green, and generally colorless, blue, red and other varieties. High dispersibility and diamond luster. No cleavage. Mohs hardness is 7.5-8 and specific gravity is 4.4-4.8.
Theoretical composition (WB%): zirconia 67. 1, silica 32.9. Sometimes it contains mixed substances, such as MnO, CaO, MgO, Fe2O3, Al2O3, TR2O3, ThO2, U3O8, TiO2, P2O5, Nb2O5, Ta2O5 and H2O. The contents of impurities such as H2O, TR2O3, U3O8, (Nb, Ta) O5, P2O5 and HfO2 are relatively high, but when the contents of ZrO2 and SiO2 are relatively low, their physical properties also change, their hardness and relative density decrease, and they often become amorphous. Therefore, many varieties are formed: Shankoushi, TR2O3 10.93%, P2O517.7%; Dashanshi, TR2O3 5.3%, P2O5 7.6%; Miaomushi, TR2O3 9. 12%, (Nb, Ta)2O5 7.69%, with high uranium and thorium content; Cyrtolite with high contents of TR2O3 and U3O8 is named after the crystal plane bending. Hydrated zircon containing H2O2 ~10%; Beryllium zircon, BeO 14.37%, HFO 26.0%; Hafnium-rich zircon, HfO2 can reach 24.0%.
Zircon is an accessory mineral in various igneous rocks. Alkaline rocks and alkaline pegmatites are rich in comprehensive minerals, which are famous in southern Norway and Urals region of Russia. Zircon is also often enriched in placer. The world's important gem-grade zircon is produced in Laos, Cambodia, Myanmar, Thailand and other places. There are also gem-grade zircon in alkaline basalt in eastern China. Zircon is the most important mineral raw material for extracting zirconium and hafnium, and it is also used in national defense and aerospace industry.
Zircon is a silicate mineral, which can be divided into two types according to its physical properties and chemical composition: high type and low type. Most of the crystals with complete crystallization are "high type"; Those with poor or no crystals are "low type". There are also three types: high, medium and low. But in terms of gem value, high-type zircon is more valuable.
Zircon is a kind of natural gem with high dispersion value and refractive index second only to diamond. Colorless and transparent zircon resembles diamond and is a good substitute for diamond. Commonly used stones are colorless, reddish brown, chestnut, green and so on. However, the most popular colors are blue and colorless, among which blue is of high value and generally undergoes artificial heat treatment. Many zircon on the market are sold after heat treatment. This is because the treated gemstone is more beautiful and more marketable than the original gemstone.
Zircon crystal belongs to tetragonal system, a0=0.662nm, c0 = 0.602nm；; Z=4. In this structure, Zr and Si are alternately arranged along the C axis to form a tetragonal body-centered unit cell. The crystal structure can be regarded as a combination of [SiO _ 4] tetrahedron and [ZrO _ 8] triangular dodecahedron. [ZrO8] triangular dodecahedron is closely connected in the direction of B axis in the form of * * * ribs.
Complex tetragonal biconical crystal, D4h-4/mmm(L44L25PC). The crystal is square, biconical, columnar and plate-shaped, and its shape is closely related to its composition. Principal simplex: quadrangular column M, A, quadrangular bipyramid P, U, complex quadrangular bipyramid X. Knee twins can be formed. You can connect with xenotime regularly ... >>
Question 3: Is zircon valuable? About how much? What are the prices of natural zircon and artificial zircon respectively? The price of 10 zircon is not high, and now the market is full of artificial zircon. A few dollars to a hundred Dockwra. Natural zircon is only a little blue (hyacinthus orientalis East). Natural zircon is radioactive and used as jewelry.
Question 4: What color zircon is good? Valuable only natural zircon that reaches the gem level is valuable. But this is not enough.
At present, the colors are white, light yellow, light red and pink.
Common ones are man-made.
Question 5: Which is more expensive, zircon or diamond? Diamonds are much more expensive than zircon in value.
Diamonds are also much rarer than zircon.
It is recommended not to buy zircon when buying gems. The contents of radioactive elements U and Th in zircon are very high, so wearing zircon is not good for your health.
Question 6: Is natural zircon valuable? Natural zircon is widely used to embed jewelry and handicrafts because of its similar color and clarity to diamonds. However, due to its large reserves, there are many kinds of similar gems, which are of little value.
Question 7: Is white stone valuable ~ How much worse than diamond ~ What's the difference between white stone and diamond? White stone has no value at all, so it can't be compared with diamonds.
Zircon diamond-cubic zirconia scientific name:
Cubic zirconia is the most beautiful artificial product.
Because it is the same as baddeleyite in nature, it is also called baddeleyite.
Zircon. CZ drill was drilled by Russian scientists in 1975.
It was successfully developed because its properties are very similar to those of natural diamonds.
Close, so it is still often used to make diamonds.
The best substitute.
CZ diamond not only has hardness (9 degrees, CZ is 8.5 degrees) second only to ruby and sapphire, but also has birefringence and high dispersion (0.044 for diamond and 0.06 for CZ) that natural diamonds do not have. Due to birefringence, zircon diamonds show natural diamond luster in any light or even sunlight, and due to its high dispersion, zircon diamonds show gorgeous fire color (also known as fire color) when worn.
Zircon has a variety of colors, including blue, black, red, purple, yellow, green and other colors. Innocent luster and beating bright colors make every gem as bright and pure as the eyes of an idle angel. Therefore, in recent years, it has been widely favored by western jewelry designers and created a beautiful life for her. Let me tell you a little secret. In the eyes of westerners, wearing red zircon can not only play a hypnotic role, but also drive away the plague and defeat evil. Zircon and turquoise are the birthstone of December, symbolizing success and victory.
Question 8: Hello, I want to ask if zircon is expensive. Natural zircon still has some value, and you can buy it for hundreds of pieces. However, most of the zircon mentioned by many merchants is actually CZ, that is, synthetic cubic zirconia, which is of little value. It is ok to wear it as a trinket at ordinary times, but don't buy it expensive. Natural zircon is called "hyacinthus orientalis" in the market. You can ask hyacinthus orientalis when you ask, so the probability of being cheated should be lower. Of course, the value of a gem depends on the degree of personal love. As long as you think it is worth it, don't care too much. Hope to adopt.
