What is 3a zircon, and the disadvantages of 3a zircon

Zircon is a silicate mineral, which is the main ore for refining zirconium metal.

Zircon, also known as zircon, is the December birthstone and symbolizes success.

Triple A is the first-level standard:

1. No crooked tip, no loss of roundness, no flower tip;

2. Wireless strip, no trachoma, good brightness;

3. The layout structure is good, and the table size is moderate, about 53% to 57% of the grain diameter.

The disadvantages of 3a zircon are as follows:

1. Zircon is a common gemstone mineral, but some low-type zircon contains radioactive elements.

Therefore, some low-type zircon is radioactive, especially the bright orange low-type zircon, and it is best not to wear it as jewelry, such zircon is likely to be radioactive.

2. Therefore, if it is a zircon for jewelry, low-type zircon is unacceptable, and low-type zircon is a zircon that crystalline becomes amorphous due to radioactivity, which is likely to be radioactive, so zircon for jewelry and jewelry will only use high-type zircon.

AAA grade (3A) zircon is a high refractive index.

Strong gloss, high birefringence, high density, high dispersion.

and zircon with typical spectral characteristics.

Zircon [gào shí] (English name: zircon) is a silicate mineral, which is a refined metal zircon.

The main ore. Zircon is widely found in acidic igneous rocks and is also produced in metamorphic rocks.

and other sediments. Chemical properties of zircon.

It is very stable, so you can also see gem-quality zircon rubbers in the gravel of the river. There are many kinds of zircon, and different zircons will have different colors, such as black, white, orange, brown, green or colorless and transparent. Cut gem-quality zircon is much like a diamond.

Zircon used to be called zircon.

The highest 5A is selected from 3A, and most of the zircons used on the market are 3A, zircons with high refractive index, strong luster, high birefringence index, high density, high dispersion and typical spectral characteristics.

The difference between zircon and diamond.

1. The essence is different.

Diamond is a polished diamond, a natural mineral, an elemental crystal composed of the element carbon; Zircon is a silicate mineral.

2. The lighting is different.

Diamonds are homogeneous, completely black under orthogonal polarizers, and have high hardness; Zircon, on the other hand, appears bright and dark under an orthogonal polarizer.

3. The physical characteristics are different.

Diamonds are lipophilic, there are ballpoint pens that can easily leave uninterrupted marks on diamonds, zircon is not lipophilic, and ballpoint pens cannot leave uninterrupted clarity marks on their surface.

4. The optical phenomenon is different.

Zircon has a strong birefringence, i.e. it has two refractive indexes, and the difference between the two refractive indices is large. As a result, a very special optical phenomenon is produced, when the finished zircon is observed with a magnifying glass, it can be seen from the top surface that there are obvious double shadows on the bottom surface and the ridgeline. Because diamonds are "homogeneous", there is no double shadow, which can distinguish zircon from real diamonds.

Introduction to ZirconZircon is a silicate mineral, which is the main ore for refining zirconium metal. Zircon is widely found in acidic igneous rocks and is also found in metamorphic rocks and other sediments. There are many types of zircon, and different zircons will have different colors, such as black, white, orange, brown, green, or colorless transparent.

Cut gem-quality zircon is much like a diamond. Zircon used to be called zircon.

The origin of zirconZircon is produced as a secondary mineral in various igneous rocks; Zircon is chemically stable, so it is often preserved in sandble, and occurs as detrital in sedimentary rocks and sedimentary metamorphic rocks, and the real mining value of zircon is sand zircon deposits. Mineralization can be enriched in alkaline rocks and alkaline pegmatites, and the famous sources are southern Norway and the Russian Urals. Zircon is also often enriched in placer mines.

The world's most important gem-quality zircon is found in Laos, Cambodia, Myanmar, Thailand and other places.
