A good golden-green cat eye requires the eyeliner to be located in the center of the arc, clear and bright, and flexible in opening and closing.
It can be said that such a gem can only be formed by a coincidence among coincidences. Therefore, the golden-green cat's eye is a very precious gem, and there are very few that exceed 2 carats, so the size has a great influence on the price.
Among gemstones of the same size, the price of a gem with a thick girdle is significantly lower than that of a gem with a moderate girdle. This is because the girdle of a curved gemstone is too thick, which increases the weight and is difficult to set.
Defects and cracks will also seriously affect and reduce the value of gemstones. Therefore, the emerald cat's eye that Han Xiaoxiao brought is definitely the best quality among the emerald cat's eyes.
Generally, chrysoberyl is often evaluated based on factors such as the beauty of its color, particle size, and number of flaws. Cat's eye is very precious due to its special light effect. A high-quality cat's eye of over 10 carats can be worth millions of dollars.
"One million dollars?" Han Xiaoxiao was a little disappointed.
Liuxu patted her head and said: "Such a high price is already very good."
"What about my piece? Isn't the tourmaline cat's eye valuable?" Han Feng was a little dumbfounded and a little anxious. This is also a treasure, right?
Liuxu smiled softly and said: "This piece of gold-green tourmaline cat's eye is rare in this color, and it is larger, so its value is not low. After all, the production of cat's eye tourmaline is relatively small, and the collection value is also higher.
"
"How high is very high?" Although Han Feng guessed that the price was not high, she was still unwilling to accept it.
Han Peacock said with a smile: "It depends on what kind of beads you can get out of this tourmaline cat's eye. The cat's eye effect of tourmaline is because there are parallel tubular inclusions inside the tourmaline. This inclusion reaches a certain density and moves vertically.
In the direction of parallel inclusions, there will be a bright line under the point light source, called a cat's eye.
Only when such tourmaline is cut from raw material will it have a cat-eye effect. Take it over and let me take a look. The color looks a bit dim, as if there are a lot of inclusions inside. From my perspective, the gemstone crystal is not very transparent and the quality is not very good.
So high!"
Han Kongque just looked at the gem in Han Feng's hand from a distance. The color was uncertain, as if it was mixed with a lot of impurities. It seemed that the transparency was not high. The reason for this was probably that it was in the gem crystal.
There are more inclusions.
However, since the cat's eye effect occurs, it can be understood that it is because some other minerals are mixed inside the gemstone that it can produce such an effect.
It's definitely not good enough in terms of clarity, but the cat's eye effect can add points to it. Besides, this gemstone is quite large, so even if the color is not bright and translucent due to the influence of internal inclusions, it's still pretty good.
But a tourmaline cat eye like this costs only seven to eight thousand yuan at most, which is really incomparable to the emerald cat eye that Han Xiaoxiao brought just now.
However, it cannot be said that this piece of tourmaline cat's eye has no value, because the cat's eye effect is generally found in red tourmaline and green tourmaline. This piece of green tourmaline also reflects a trace of golden light, so it should be the golden green color closest to the real cat's eye stone.
If this is the case, then the price of this gem can increase a little, but definitely not too much.
It was also because of this that Han Kongque wanted to take a good look. Otherwise, he would not waste time looking at a gem with no characteristics. After all, he has seen too many gems these days, and they are of all kinds.
, the quality is better than this one, and the truck bucket is light.
After taking the gem, Han Kongque felt something was wrong at first glance, so he naturally frowned.
"What's wrong?" Liuxu saw it most clearly.
Han Peacock said while looking at it: "This doesn't seem to be tourmaline."
"Not tourmaline? What is that?" Qin Mingyue asked curiously.
"There are many. Gemstones that can produce cat's eye effect in nature include beryl, apatite, quartz, kyanite, etc., but they are not as precious as gold-green cat's eye. Tourmaline cat's eye: has less hardness. Others are like quartz cat's eye.
, artificial cat eyes, the hardness is low." Han Peacock explained.
In fact, Han Kongque didn't say it, because "cat's eye" is not the name of a gem, but an optical phenomenon that appears on some gems, so there are many gems with this optical effect.
This optical effect means that when a gemstone ground into a hemispherical shape is irradiated with strong light, a narrow and bright reflection will appear on the surface, which is called "cat's eye flash" or "cat's eye living light".
Then it is named according to what the gemstone is. If the gemstone is quartz, it is called "quartz cat's eye". If it is chrysoberyl, it is called "golden green cat's eye".
There are many types of gemstones with cat's eye sparkle, and according to statistics, there may be as many as 30 types. In addition to quartz cat's eye and gold-green cat's eye, there are also "pyroxene cat's eye", "aquamarine cat's eye", etc. on the market.
Since the golden-green cat's eye is the most famous and precious, it is customary to call it "cat's eye" for short. Other cat's eyes cannot be called this way.
Qin Mingyue didn't care about anything else. She was just curious, so she asked again: "Is artificial cat eyes valuable?"
Han Kongque said: "Of course, the reason why there are artificial ones is because they are beautiful. Artificial cat's eyes are cat's eye stones made of artificial glass fiber. They come in brown, yellow, blue and red, but the artificial cat's eye stones appear at the top of the arc. 2-
There are 3 bright bands, and only one bright band appears in natural cat’s eye stone.
Observing with a magnifying glass, you can see that the artificial cat's eye stone has a hexagonal honeycomb structure and low hardness, but you can't say it's not beautiful, so there is a market for it. Aren't you women just visual animals?"
"You are not a visual animal, so what's going on now?" Liu Xu looked at Han Peacock's shining eyes and said disdainfully.
Han Peacock laughed and said, "I'm so jealous when I see money."
"Is it easy to see money? Is there something extraordinary about this tourmaline cat's eye?" Liu Xu was also curious at this time.
Han Feng became a little excited and said hurriedly: "Isn't this an ordinary tourmaline cat's eye?"
Han Kongque raised his head, looked at Han Feng and said, "Did you get this gem from the pile of emeralds?"
"Yes!" Han Feng said matter-of-factly.
Han Kongque said with a smile: "The gem over there is a specially selected emerald. This gem was actually considered to be tourmaline at first. It seems because the color inside is too confusing."
"Color?" Liuxu looked at the gem in Han Peacock's hand thoughtfully.
Meiren Zhou, on the other hand, was much more professional. She directly took a small flashlight and began to illuminate the gem from different angles.
Han Peacock was a little speechless. Why couldn't he develop this good habit?
No matter how tacky this behavior may seem, it is really classy. Anyone who sees it will know that this is an expert.
Looking at Meiren Zhou, whose eyes were starting to shine, Han Peacock laughed softly.
Having just received this gemstone, Han Kongque carefully examined its internal condition. Because of the parallel-growing tubular inclusions, Han Kongque concluded that it was a tourmaline.
After the parallel-growing tubular inclusions contained in the tourmaline reach a certain density, if the tourmaline is irradiated with a point light source, a bright line will appear in the direction perpendicular to the parallel inclusions, which is the cat's eye effect. This is what people often say.
cat's eye tourmaline.
Jewelry made from cat's eye tourmaline has a cat's eye effect and is very popular. If it is a golden-green cat's eye, then the color reaches this honey color, which is the most beautiful.
To identify the quality and value of cat's eye tourmaline, the first thing to look at is the cat's eye flash. When a piece of cat's eye tourmaline is exposed to a focused flashlight or direct sunlight, the straighter, finer and brighter the flash, the better the quality and the value.
The higher.
Second, observe the color of the tourmaline. Usually, the color of the cat's eye tourmaline is not bright enough. For example, among the golden and green cat's eye tourmalines, the color is grayish white, greenish, yellowish, and the color is lighter, and the quality is not good.
The good ones are transparent honey color.
Third, look at the purity. The fewer defects such as ice cracks and inclusions contained in cat's eye tourmaline, the higher its quality value.
Therefore, the quality and value of cat's eye tourmaline are mainly affected by its purity, fineness, the position of the cat's eye line and its color.
The cat's eye tourmaline is of high quality, the crystal is transparent and bright, the color is bright and distinct and stands out from the background, the eyeliner is located in the center of the tourmaline's curved surface.
In addition, because tourmaline contains many ice cracks and inclusions like crystal, cat's eye tourmaline with clear and pure crystals is very rare and extremely valuable.
The reason why Han Peacock was not interested in this gemstone at first was because the color was not transparent, so he thought there should be a lot of inclusions in it. Even if this kind of tourmaline was a tourmaline cat's eye, its value would not be high.
When he took it over and took a look, Han Peacock discovered that the transparency of this gemstone was very good, and it was also golden-green. In addition, the cat's eye inside was honey-colored yellow, which made it look even more beautiful.
So, why did Han Peacock look at the dim and opaque gem just now?
After taking it over, Han Peacock discovered that it actually changed color. When the light shines on the gem, it will actually emit a red light.
Perhaps because this gem has not been cut or polished, the light is refracted when it hits the gem, so the golden, green and red light are intertwined, and it looks dim from a distance, as if the gem is not bright.
Just as transparent.
Now this gem was shined by Zhou Meiren with a flashlight, and the whole gem turned into ruby.
"Isn't this emerald?" Han Feng was dumbfounded at first.
Qin Mingyue was also a little confused: "It was golden-green just now, right? Why did it turn red when the light shined on it?"
"I know, this is a ruby." Han smiled and said proudly.
"Are you stupid? You don't need to shine a light on it, but it's golden and green." Han Feng said.
Han Xiaoxiao laughed and said: "What do you know? This is a ruby in the dark night."
Looking at the triumphant Han Xiaoxiao, Han Peacock broke into a cold sweat. It seems that his silly son will have a hard time getting ahead in the future. (To be continued.)
