Perhaps seeing everyone's doubts, the dive guide smiled and said: "The color-changing effect, fire color, such a special gemstone is easy to identify, so I identified it faster."
"Is this sphene stone weighing two grams?" Chen Qing asked at this time.
"Two grams is ten carats, which is quite a lot. Anything over one carat is very precious," Qian Dao said.
"The color of this sphene is green, and its value should be better among the sphenes of various colors. At your national jewelry exhibition in November, a 10-carat brown-green sphene appeared, which cost about 100.
Dollars per carat.”
"The price quoted in that place won't be very cheap. They also catch and kill each one, so it shouldn't be difficult to use as a reference price." Han Kongque shook his head and said.
The dive guide smiled and did not continue to argue about the price, but said: "Shenite is very popular in Europe, America, Japan and India in Asia, but it is still not popular in your country because the hardness of sphene is very low and the market is not very popular.
, coupled with the lack of promotion, the prices in your country are not very transparent.”
Song Min said at this time: "Domestic processing is dangerous. Think about the processing of turquoise and so on? I don't dare to change the model."
"The quantity is too small, so many jewelry companies have no motivation to promote it. You are very lucky to find two such big ones." The dive guide looked at Han Peacock with envy.
Han Peacock laughed twice and said: "Lucky? Maybe! Show me these again."
Han Kongque casually pulled a backpack next to him, opened it, touched it with his hand, and took out a piece of green ore.
Chen Qing and others looked at Han Kongque in surprise. That backpack was not his. How could there be gems in it?
However, Han Peacock took out the gem from it.
"Huh? Shen Shi again?" The dive guide looked at Han Peacock in surprise.
Han Peacock put his hand into the backpack again, touched it, and took out another piece. This piece was pink. These were the ores found near the piece of sphene, so Han Peacock thought they might all be sphene.
Since this diving guide was an expert in minerals, Han Kongque took it out and asked her to help identify it.
"Pink sphene? Black? And chocolate color? There are only a few colors of sphene, and you have collected them all?" The dive guide became more and more shocked as he looked at it. In the end, he stopped talking and stared directly at Han Peacock's hand.
.
The backpack beside Han Peacock has now become a different dimension. Every time Han Peacock reaches out, he can take out a very rare and precious sphene stone.
The usual colors of sphene are green, yellow-green, and occasionally pink, black and chocolate, showing a bright rainbow effect. After a while, Han Peacock took out a dozen pieces of sphene of various colors. At this time
Not only the dive guide was shocked, but Chen Qing and the others were also silent.
They all knew that Han Kongque carried space with him, but they were still a little frightened by his performance in such a miraculous way.
"This piece is not a sphene, but an amethyst." After being silent for a long time, the dive guide was already a little numb, so she made the identification mechanically.
"This piece is rhodochrosite, and so is this one. This brown piece is not, it is calcite, and the dark gold piece is not rhodochrosite, but is also calcite. However, such large calcite is also very rare."
Calcite is a calcium carbonate mineral, which is the most common natural calcium carbonate. Therefore, calcite is a widely distributed mineral.
Calcite crystals have various shapes, and their aggregates can be clusters of crystals, or they can be granular, massive, fibrous, stalactite, earthy, etc.
Knocking calcite can yield many square fragments, hence the name calcite.
The calcite that Han Kongque brought out was quite beautiful, it was a diamond-shaped crystal, and it came in brown and dark gold colors.
The dive guide once again looked at a pile of ores and picked out some calcite. These calcite stones are not small in size and have different colors. The only common feature is that they are beautiful. They are all very beautiful.
Whether it is white, five colors, or other colors, they are all very beautiful.
The color of calcite changes due to the impurities contained in it. For example, when it contains iron and manganese, it is light yellow, light red, brown black, etc., but it is generally white or colorless.
Especially the colorless and transparent one. When the dive guide picked it up, he actually saw a double image inside.
"This is the best, also called Ice Island Stone. It is very rare." The dive guide said in amazement.
Colorless and transparent calcite is also called iceland stone (so named because it is abundant in Iceland). This kind of calcite has a wonderful feature, that is, objects can be seen in double images through it. Therefore, iceland stone is an important optical material.
Material.
Calcite is the main mineral in limestone and marble and has many uses in production and life.
We know that limestone can form caves, and the stalactites, stalagmites, white marble, etc. in the caves are actually made of calcite.
"This piece definitely exceeds 300 carats. Even if it is carved, it will not be reduced much. It is the largest calcite gemstone in the world." Picking up the largest piece, the submarine guide's eyes almost popped out.
Although the price of calcite is not expensive, money cannot measure anything that is linked to being number one in the world.
On August 17, 2004, a jewelry studio in Guiyang, Guizhou, donated the two largest calcite gemstones in the world that it successfully developed to the China Geological Museum for collection.
One of the gemstones is a light yellow, turned Portuguese-cut calcite gemstone, weighing 172.5 carats; the other is a golden brown, close-cut hexagonal calcite gemstone, weighing 84 carats.
The weight of these two gems exceeds the 75.8-carat golden-brown step-cut faceted calcite gem collected in the Smithsonian Museum in the United States.
Nowadays, there are many calcites in Han Kongque that exceed one hundred carats. What can the dive guide say?
"Isn't this dull, mixed-colored ore a precious gem?" At this time, there was no way to find a more precious gem, so Gu Lie simply picked a more attractive ore and picked it up for the dive guide.
identification.
The potential guide looked at Gu Lie speechlessly. Is the luck value of these people maximized? And not a fixed value? It is always the strongest, largest, and constant.
"No way? Could it be that this one is also a rare gem?" Gu Lie said in astonishment.
Han Kongque and others were also attracted by the gem in Gu Lie's hand. The color of this piece of ore was very mixed. You could see dark cyan, blue, green, purple and other colors slowly transitioning at once.
"There are so many colors, they must be very rare." Chen Rui said with a smile.
Song Min hesitated and said: "Isn't this bismuth?"
The dive guide was silent for a while and then said: "This is bismuth, it's a bit radioactive, so you'd better be careful."
"What is bismuth?" Chen Qing asked.
"A kind of metal, this is bismuth crystal." Qian Dao said.
Bismuth is a silver-white to pink metal that is brittle and easily pulverized. The chemical properties of bismuth are relatively stable.
Bismuth exists in the form of free metals and minerals in nature. Previously, bismuth was considered to be the stable element with the largest relative atomic mass. However, in 2003, it was discovered that bismuth has extremely weak radioactivity.
Bismuth crystals are obtained by melting high-purity metal bismuth and crystallizing during slow cooling. Crystal bismuth generally has a complex and regular shape.
Crystal bismuth will be oxidized, and the thickness of the oxide film will determine the color of the reflected light, thus forming an oxide film of various colors, which looks very dazzling.
"It's not a treasure, it's just a mineral." Gu Lie said a little disappointed.
Song Mindao: "Mineral specimens can also be collected. The most important thing is that they are still very beautiful."
"Although this cannot be used as a gemstone, it is also a rare natural metal crystal. It is a rare treasure among mineral specimens." Qian Dao said.
Han Kongque said with a smile: "Mineral specimens are also very expensive. For example, the price of a large rhodochrosite specimen is around hundreds of thousands of dollars each."
As he said that, Han Kongque took out a larger piece of rhodochrosite. Although the ore he took out just now was a lot, it was all very small. Of course, this is relative.
A backpack can hold hundreds of dove egg-sized ores, but palm-sized ores cannot hold many.
The rhodochrosite ore that Han Peacock took out this time was larger than the plate. Such rhodochrosite ore is definitely relatively large.
"Isn't it beautiful? This piece of rhodochrosite is actually sea blue, which is absolutely rare." Han Peacock said a little proudly.
"Isn't this rhodochrosite? The particles are not too big. They are not a whole, they are clustered together, so they look larger. Blue ashlar does not seem to grow big." At this moment, Song Min hesitated a little.
The way.
"Isn't it rhodochrosite?" Han Peacock's face changed a little, it turned red.
The dive guide affirmed: "This is not rhodochrosite, but blue ashlar, sea blue, so blue that it is thrilling."
"Blue ashlar? There are so many blue ashlars clustered together, it's really beautiful." Yuan Peng happily glanced at the blushing Han Peacock and said.
"This is indeed blue ashlar. It is produced in the form of small round particles and is distributed in volcanic rocks. The important producing areas are the ancient volcanoes in Germany and Morocco. Are there volcanoes under the sea?" The submarine guide looked at Han Peacock and wanted to analyze Han Peacock's behavior.
Expressions to get some information.
If it is really found near the ancient volcano, combined with the location where Han Kongque went into the water, the submarine guide can deduce that Han Kongque found these precious ores from the seabed within that range.
Of course, Han Kongque had no worries. Even if he told the diving guide, she wouldn't believe him. Even if he did, she wouldn't have the ability to go into the water to look for him.
"Blue ashlar is very easy to identify. Its crystals are in the form of rhombohedral dodecahedrons, usually in the form of granular aggregates, with colors ranging from sky blue, blue or greenish blue, and with glass luster." The submersible guide did not obtain effective results on Han Peacock's face.
She was a little disappointed with the information, but her professionalism allowed her to continue explaining. (~^~)
