Can anyone tell me what these two stones are? Thank you!

That is a crystal stone, you can collect yourself, you can also reprocess it for decorations, this stone is not by kilogram **, but to see the purity, color and shape, if it is a crystal rough stone, it is expected that the price will not exceed 100 yuan.

We call this kind of stone flint in Lianyungang dialect, and there will be sparks when you rub it.

Smooth? Isn't it the stone of the Ding in Donghai County?

The one on the right is worth the money.

It shouldn't be a good stone! Where did you get it? Based on the environment in which the stone was excavated, it can be concluded in general. It's not so absolute, I don't think it's a good stone. Dude is still cautious! Don't be fooled! You go to the Minerals Bureau and ask.

There are many such stones in our house, the same. Out of the sand, polished. The crystal stone mentioned above or what Tianhuang stone is all fooling you. There are many such stones on our seashores and in our mountains.

Common, like they say those stones are some rare things, if it's really crystal, you put it in the water, and then wash it with water, and wash it for a few minutes, the original things are gone, then it means that it's a good thing, then congratulations, if not, then you boldly put it into the fire and burn it for a while, if the surface is black, it means that there is a combination of C and the like, so it's not a good thing that can be tested at once.

Good luck

I'm a farmer, and I always dig out such stones when I plough the land!! Hehe!! It seems that your stone is not as pure as my table legs!!

I'm a native of the East China Sea, and I can.

The one on the left is a low-quality quartz, commonly known as flint, if two pieces collide violently, sparks can be generated, ** at 100 yuan a ton, there are everywhere in the East China Sea.

The one on the right is also a low-quality crystal, commonly known as a flower stone.

** Transparent within 50 yuan Opaque reference price 10 yuan If there is a special pattern in it, then you will make a big reference price of 10,000 yuan to n yuan.

Tian Huangshi, it's so expensive, it's a good thing. Do you have it, so big, you got rich. Congratulations.

Cold jade, diamond.

There are some in the bloody rivers and lakes!

If it's Tian Huangshi, you'll send it.

That's a very bad jade, worthless

Ordinary stones are not worth much!

If it's Tian Huangshi, you'll send it. It's a pity that it's a stone in the yellow sand.

Both are quartz pebbles, not much value, quartz pebbles, the main chemical composition is silica, followed by a small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. The reason for its formation is the broken rock, the edges and corners disappear through long-distance transportation, forming a garden-shaped or oval stone, produced in the places of rivers and rivers in various places, there are many varieties, the stone pattern has strips, stripes, spots, corrugations and irregular curved strips, etc., mostly black, yellow, blue-gray, its shape is mostly round and shaped, the surface is fine and smooth, flat and smooth, the stone is solid, most of them are irregular blocks, with wax or glass luster, translucent. It can cut the glass and leave scratches, no odor and light odor, and it is not easy to heat when it is quickly rubbed.

Visually it's a piece of limestone, it's not of much value, you can cut it open and look inside, maybe it's not the same inside.

Limestone, referred to as limestone, is a carbonate rock with calcite as the main component.

Sometimes it contains dolomite, clay minerals and detrital minerals, gray, gray-white, gray-black, yellow, light red, brown-red and other colors, the hardness is generally not large, and there is a violent chemical reaction with dilute hydrochloric acid.

It belongs to sedimentary rocks according to its genetic classification. Mineral particles and crystal structures are rare, and the surface is smooth and small granular. The hardness varies, and some dense limestone can be polished.

In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide, and is an indispensable flux limestone in the metallurgical industry.

Summary. Hello dear, according to your description, these two pieces are quartz stones The first piece is of high quality and good purity The second piece has low purity and poor permeability The main component of quartz stone is silica crystal The quartz stone of average quality is pebble The better quartz stone is the agate The better quartz stone is the crystal stone The above are all natural Artificial is glass.

What are these two stones, and can anyone explain?

Hello dear, according to your description, these two pieces are quartz stones The first piece is of high quality and good purity The second piece is pure and noisy, and the degree is low and the permeability is poor The main component of quartz stone is silica crystals Quartz stone of average quality is a pebble Better quartz stone, that is, there is no agate No better quartz stone, it is crystal stone The above are all natural Artificial is glass.

Aren't pebbles granite?

Hello dear, Honghuai according to your description is like a friend, yes pebbles are a kind of granite stone. As a pure natural stone, pebbles have experienced the sand and gravel produced by the uplift of the ancient riverbed after the crustal movement thousands of years ago, and have experienced the impact of mountain floods and the continuous extrusion and rubbing of rubbers in the process of water handling, and gradually lost their edges and corners and rounded.

This stone baitou should be quartzite, in fact, it is the same material composition as the DU crystal, simple dao

Said that the version of the crystal is a mature quartz right.

Quartzite, the main mineral is quartz, which can contain mica minerals and hematite, goethite, etc. Quartzite is a metamorphic rock composed mainly of quartz (quartz content greater than 85%), which is formed by metamorphism of quartz sandstone and siliceous rock. It is generally formed by the recrystallization of quartz sandstone or other siliceous rocks through regional metamorphism.

It is also possible that quartzite is formed by thermal contact metamorphism of siliceous rocks near magma.

Gypsum is a monoclinic mineral, which is a hydrate of calcium sulfate (CaSO4) whose main chemical composition is calcium sulfate. Gypsum is a versatile industrial material and building material. It can be used as cement retarder, gypsum building products, model making, medical food additives, sulfuric acid production, paper fillers, paint fillers, etc.

Jasperite, a dense and hard siliceous rock. It is mainly composed of chalcedony and self-generated quartz, with iron oxide and organic matter mixed, so it is often red, brown, green, rose, etc., because it is the first position of iron oxide color, so it will never change color in the oxidation environment in the air. Much more stable than bloodstone.

In addition, it is mainly siliceous minerals, which are hard, not easy to weather, not easy to wear, and not afraid of acid and alkali erosion.

This is Wada.

Yushan incoming materials. Hetian source jade mountain material.

There is no weathered surface du skin or the regolith layer is very thin jade blocks, mostly from the mine outcrop dao or the face of the original ore mined, also known as mountain jade, ballast jade, ancient called "baogai jade", refers to the original jade produced in the snow mountains of the Xinjiang region is very high.

At present, it is mainly produced in the Kunlun Mountains, producing green jade and white jade, and high-quality jade is mainly distributed in high-altitude areas, with thin air and extremely low temperature, which has caused great difficulties for the collection of Hetian mountain materials, and mining is limited by the season. At present, as the mountain material becomes less and less, the increase in height makes the mountain material very difficult to mine.

Hetian jade mountain material in the narrow sense: the origin is Hetian jade in Xinjiang.

Generalized Hetian jade mountain material: there is no restriction on the place of origin, and the Hetian jade produced in Xinjiang is of the same family, and the content, refractive index, structure, specific gravity, color, hardness and other aspects of various elements are basically the same as the jade produced in Xinjiang, and the main production areas are Xinjiang, Qinghai, Russia, South Korea, and Canada.

The blockiness is large and small, showing obvious edges and corners, the quality is not as good as the seed jade, it is slightly rough, you can see the graininess, no skin color, poor oiliness, and some mountain materials are close to the outside with the color of brown sugar.

This is a mountain material and Tian Yu Guan Gong pendant, with leather carving, blue and white Qin red material (this Qin red skin is a bit fake). Similar to the figure in the figure, this ** costs about 4000-5000 yuan, and the actual ** should be below 2000.

This is Xiuyan jade, the texture is not very hard, but it is very good to make a handle, afraid of bumping.

Qingyu, but this skin is baked, and it's disgusting to fake.

Maybe it's the rain flower stone,Its composition is mainly silica, among othersThe red component is iron ions(ferric ions) andFerrous ions(divalent iron ions). Yuhua stone is a pebble of agate, opal, chalcedony, quartz, etc., which can be found in the sediments of river beds and river terraces, the most famous of which is the rain flower stone produced by Nanjing Yuhuatai. Yuhua stone is made of agate, opal, chalcedony, quartz, etcPebblesIt is seen in the sediments of riverbeds and river terraces, and the rain flower stone is divided into two categories: fine stone and coarse stone, the fine stone is mainly agate, the stone is delicate, the color is gorgeous, the roundness is high, and the crystal is lovely; Coarse stone is coarse, mainly quartz or metamorphic rock, and has a low value.

The beautiful rain flower stone can often present a variety of landscapes, people, birds and beasts, trees and other scenes, so that people reverie and think into the stone.

Due to the wide variety of rain flower stones, its genesis and chemical composition are extremely complex. Take agate gravel as an example, it is ** in the original agate. It is generally believed that primary agate was formed from the residual hydrothermal fluids of magma.

This kind of hydrothermal filling is in the voids of volcanic rocks such as basalt and rhyolite, and due to the different shapes of the voids, it may become an agate ball or an agate vein. Through the action of natural forces, the original agate falls off, and then through the impact of mountain floods, flowing water transports, and grinds into pebbles. This is what we see in the gravel layer.

Yuhua stone is famous for its strange patterns and colorful natural beauty. Its circular pattern is formed by silica gel liquid surrounding the voids and cavities of volcanic rock, starting from the inner wall, and precipitating layer by layer from the outside to the inside. During its growth, periodic diffusion of colored ions and compounds often occurs.

The main chemical component of virgin agate is silica, followed byA small amount of iron oxide and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds

This color and texture looks like jade. It belongs to the Hetian green jade category, and the quality is relatively poor. With skin color, with the technique of embossing with clever colors. The process is average. It's okay to play with, it's not much collector's value. FYI.

Pebbles, this special shape can also be found in the mountains of my hometown.

Judging from the **, the thing is probably Hetian jade sugar leather or Afghan jade.

This is a piece of jade. It is estimated that it is Xiuyu or jade from Henan.

This is jade that has already been processed.

Picked up in **, it feels like Hetian jade.
