How to identify the crystal stone, where is the goods coming in, if it is true.

The East China Sea is the largest crystal market.

1 Eye: Natural crystals in the process of formation. Often affected by the environment, there are always some impurities, when observing the sun.

A faint uniform fine striated or catkins-like substance can be seen. The fake crystal is mostly smelted with residual crystal slag and glass slag, polished and colored, and there are no uniform stripes and catkins.

2 Tongue licking: Even in the hot summer, licking the surface of the natural crystal with your tongue gives you a cold and cool feeling. Fake crystals. There is no cooling sensation.

3: Light natural crystal erected in the sun. No matter which angle you look at it. can emit a beautiful brilliance. Fake ones are not.

4: Hardness: Natural crystal has high hardness. Use gravel to lightly scratch the ornament. Leaves no traces. If there are traces. It's a fake crystal.

5: Check with a polarizer: Rotate 360 degrees under the polarizer and have four bright and four dark changes are natural crystals, and those that do not have fake crystals.

6: Check with dicolor: natural amethyst has dichroism, and false crystal has no dichroism.

7: Check with a magnifying glass: Check with a ten-fold magnifying glass under transmitted light, and the bubbles that can be found are basically fake crystals.

This one on the picture is true! You can go to his little shop and see it's all true.

Quartz.

The composition of crystal and quartz is the same, both are silica, quartz is coarse crystalline particles, crystal is crystalline, high transparency!

Crystal pictured below. Quartz in the picture below.

Quartz stone ** is calculated according to the silicon content, 200 to 1000 tons are available.

When silica crystallizes perfectly, it is crystal; After silica gelatinization and dehydration, it is agate; The aqueous colloids of silica become opal when solidified; When the silica grains are less than a few microns, they form chalcedony, flint, and chalcedony

Secondary quartzite Quartz is a mineral resource with very stable physical and chemical properties, and the crystal belongs to the oxide minerals of the trigonal crystal system, namely low-temperature quartz (A-quartz), which is a widely distributed mineral species in the quartz group of minerals. Quartz in a broad sense also includes high-temperature quartz (B-quartz). Quartz block, also known as silica, is mainly a raw material for the production of quartz sand (also known as silica sand).

There are several categories of valuable stones:

The first category is building material stones, such as white marble, granite, pebbles, etc.;

The second category, ornamental stones, with strange stones as a typical, as long as it is a unique shape, or a unique pattern of the stone is a strange stone, the more similar the more characteristic the more valuable;

The third category is jade, such as jadeite, Hetian jade, Xiuyu, agate, crystal and other jade;

The fourth category, ores, all kinds of non-ferrous metal ores are valuable;

The fifth category, meteorites, meteorites are valuable;

The sixth category, fossils, fossils are also valuable;

The seventh category is the stone of artistic creation, such as stone carvings, stone statues, stone relics, etc.

Valuable, the key is how much the crystal rough is directly used as the end consumer products are mostly crystal holes, crystal clusters and other ornament products, most of the other crystal rough will appear on the market as consumer goods due to the huge global reserves, although it is known as the king of crystals, but in fact, the value of the commodity is not high, depending on the size, crystal perfection, transparency, clarity and other comprehensive pricing can not be generalized, if it is just a general product, The market transaction price is mostly within three digits, I hope there is a reference, good luck!

It's not worth much now, and basically no one buys it.

It's not worth much, 100 yuan is a lot.
