Probably pebbles. Under the impact of the stream for many years, the surface of the stone has been washed very smooth. Of course, a variety of shapes are created according to the original shape of the stone and some external reasons such as the impulse and position of the stream. It's like having all kinds of pebbles by the sea.

Cobblestones, our hometown is full of rivers, and you're making too much of a fuss! If you have studied geology, you will know that the stones were originally angular, but because of the long-term erosion and rounding effect of the water flow, they slowly turned into smooth pebbles.

It's just a pebble.

It may have slipped down from the mountain next to it, or it may have been formed after years of water impact, yesterday I watched the countryside and found it in a program, I forgot what the place was, they would come down a large egg-shaped stone every thirty years on the mountain, the villagers also called it the god egg, the expert finally said that it was the stone after a long time of squeezing, the wind and rain polished, forming such a shape is not strange, keep it well, no matter what, it is also a memory, hehe.

Pebbles. In the river channel, it is hit by water and other stones to make its water chestnut smooth, which is an example of overcoming rigidity with softness! ~

That's a handicraft sold at a seaside place, right?
It's made of pebbles.
It was made by someone. If you are from Dalian. You'll find a special extra box at the seaside where you sell handicrafts.
It must be a child who doesn't like it after buying it. You picked up the ones that were thrown away.

You should be talking about jade egg balls, which are natural jade materials and ornaments.

That must be a pebble!

I also think it's pebbles.

Khan, pebbles are like eggs.

Fossils are not as smooth as you say they are.
It should be a pebble of crystal marble.

Man-made, sold at major attractions.

This kind of stone, hey, it's not hitting you, it's really a very ordinary pebble, and this kind of stone on the construction site next to my house is all about cars.
-
Oh, that's a pebble.
-
Pebbles, naturally formed, you haven't heard of them.
-
Take it to the relevant departments and check it, and you'll know.

...Did you pick up the legendary pebbles?

Judging from the picture above, stone tuberculosis is generally more common except for pebbles.
Stone nodules, which often contain certain mineral clumps in sedimentary rocks that are distinct from the composition of surrounding rocks, are called nodules. Its shapes are spherical, ellipsoidal, lens-shaped, irregular, etc. Its internal structure is concentric circles, radial shapes, etc.
They vary in size, from a few centimeters to tens of centimeters or even meters. Some of its distribution is layered, and some are beaded along the layer.

If you are on a river beach, or at the foot of a mountain, you will find a stone in the shape of an egg, which is a pebble; If egg-shaped stones are found in the Late Cretaceous strata (about 65 million years ago), they are fossilized eggs of dinosaurs or reptiles.

Hello, we have received your question, and we are currently answering it urgently, please be patient
Hello! We're happy to answer for you! It's not jade.
In fact, this kind of egg stone is called opal, which is a relatively common stone. Opal is a hydrate of silica, which is an amorphous structure, so it has a certain shape, and the fracture is shell-shaped, mainly formed by colloidal precipitation of silica.

Ask how much it's worth.
It still depends on the specific value, if it is an ordinary stone, it may not have value. If it is a jade stone, it is also necessary to test its specific composition to see the purity. It is recommended that you can consult with a professional institution for offline jade identification.
Ask how much it's worth if it's true.
It is also necessary to test its specific ingredients to see the purity. to know how much.

Test the specific ingredients to see how pure they are.
Ask what is this, what is it produced in Qujing City**There is a jade institution!
Then you can estimate it in an ordinary jade store, if there is no identification, but you can't see the ingredients by looking at the appearance.

Quartz pebbles, the main chemical component is silicon dioxide, 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.

I also have it, I don't know what stone.

Summary. It may be that the egg yolk pigment deposition is not good due to the illness of individual chickens, or it may be that the inflammation of the fallopian tubes leads to cheese-like substance.
There's something like a stone inside the egg, what is it?!
It may be that the egg yolk pigment deposition is not good due to the illness of individual chickens, or it may be that the inflammation of the fallopian tubes leads to cheese-like substance.
There is no yolk in the egg, only the white and a long lump, I don't know what it is.
If this is not what was just said, it may be caused by the necrosis of the unfinished embryo and egg.
This egg is a benefit that has just been issued by the factory, not an incubated egg.
Yes, some eggs are fertilized as soon as they come out. But it didn't happen.
Oooh, thanks.

You send it to see.
How much is it?
These things can't just be said casually, and they are looking at it correctly, and then they are raised**ah, from your**, this is opal. Opal is a natural hardened di-oxide silica gel containing 5-10% moisture. Opal is different from most gemstones, it is amorphous, and some unstable amorphous structures in opal will change color and even crack due to lack of moisture, but there are also some opals with very stable structure that do not change in the normal environment.
Opal is an opal in mineralogy, containing two types of gemstones, color-changing and non-color-changing, and is a watery, non-dry, permeable crystalline silica.
Hello, I can't hear the voice.

It's a bit like a gossip graphic, so the ancients mostly used it for divination.
