"Oh my God, I read that right. www.biquge.info"Tang Hao was first attracted by the red spar, and his eyes almost popped out.

"I'll take a closer look. Wu Lao was even more excited, immediately took out a magnifying glass and other tools, carefully examined, the more he looked at it, the more shocked he became, and in the end, his jaw was about to fall to the ground, and his hands trembled slightly.

"Old Wu, is this really pigeon blood red?" Tang Hao asked excitedly.

"That's right, it's pigeon blood red, or the most flawless pigeon blood red. Oh my God, this head, how heavy it is, it is estimated that it is at least fifty carats, it should not be more than that, how is this possible. "Wu Lao came here, in fact, he was mentally prepared, because he had heard that Su Jing had a lot of treasures, but now he was still stimulated to speak incoherently.

"Looks like I'm not mistaken. Su Jing smiled faintly.

"Su ...... Mr. Su, since you recognize this gem, you are too calm, right?" Tang Hao and Wu Lao both found it difficult to accept.

Everyone knows that rubies are the most intense and beautiful in color, and they are called pigeon's blood red. Rubies that can truly be called pigeon's blood red are produced in small quantities and are worth a lot of money, most of them are produced in Myanmar, and the sheer of the cut can rival the brilliance of diamonds.

At present, there are always many merchants on the market who claim that the ruby they sell is pigeon's blood red, in fact, the definition of pigeon's blood red is very strict, for its color, clarity, hue, color saturation have almost strict regulations, the current international market price of small particles of pigeon blood red is about 2-30,000 US dollars a carat, and it is almost impossible to find in ordinary stores or channels.

In 2011, the Sotheby's auction brought two top-quality rubies from the top ruby mines, Mogok Valley. Among them, Bulgari's 27.67-carat natural Burmese ruby and diamond ring is estimated to be HK$12 million to HK$20 million, making it the largest gem-quality "pigeon's blood" Mogok natural ruby in the history of the auction. The most famous pigeon blood red is called "Carmen Lucia", born in Myanmar in the 30s of the twentieth century, after more than 70 years of wandering, was accepted by the National Museum of Natural History of the United States, as for the purchase price, only the museum itself knows, its weight is 23.1 carats.

And the pigeon in front of him is blood red, the color and transparency are more beautiful than those, and the weight is more than fifty carats. It's no wonder that Tang Hao and Wu Lao were so shocked that they couldn't help themselves, no matter who was engaged in jewelry, they would probably be stunned when they saw it.

"Mr. Su, is there an electronic scale here?" asked Elder Wu.

"Yes. Su Jing said, taking an electronic scale. Wu Lao weighed it carefully, the data showed 12 grams, which is converted to 60 carats, Wu Lao's footsteps shook slightly, and he almost fainted.

"Mr. Su, this gem ......" Tang Hao said excitedly, but halfway through his words, he stopped abruptly. He subconsciously wanted to ask Su Jing to transfer this gem to Tang's jewelry store, but after thinking about it, Nima might not be able to afford it. This gem itself is a priceless treasure, rich people generally refuse to sell it at all, even if Su Jing is willing to sell it, they may not be able to afford it, it is too painful to take it.

"Hehe, let's take a look at the other two first. Su Jing pointed to two larger sapphires.

Tang Hao was also overstimulated by this ruby, and only then did he think of the other two, looked down and took a closer look, and was shocked again. Wu Lao also shifted his attention to the two sapphires, and was also stunned again.

They first looked at the sapphire from above, and saw that the top of the convex sapphire showed six starrays, which was very beautiful. Turning and shaking his fingers slightly, the star line on it moved flexibly.

"Oh my God, this is the finest star sapphire. Wu Lao was shocked.

"There are no blemishes, it is completely transparent, the star is perfect, it is flexible, it is clear and bright, and it is such a large one, it is the first time I have seen such a superb star sapphire. Tang Hao was also excited.

"It turns out that this is called star sapphire, how to identify it?" Su Jing asked if he didn't understand, he had known about sapphire, and he had heard of star sapphire by chance, but he didn't know much about it.

"To put it simply, it's a sapphire that produces starlight. The reason for this is that the gemstone contains filamentous inclusions (in the plane of the vertical z-axis, the dissolved needle-like rutile arranged in a direction of 60° to each other. When it is cut into a cabochon gemstone, the camber should be perpendicular to the specific direction of the sapphire crystal (C-axis) to cause the six-ray star in the center of the intersection point, and occasionally the double star phenomenon can be seen, otherwise, the starlight will not be concentrated in the center due to the skew of the cut, and the crystal will become crooked. Wu Lao spoke very quickly, and after a pause in his dry mouth, he continued,

"The gemstone world has strict criteria for judging starlight, such as whether the intersection of the six star lines of a gemstone is in the center of the gemstone, whether the star line is complete and bright, whether the star line moves flexibly with the light and the rotation of the finger, and the more affirmative answers, the greater the value of the gemstone. Brightly colored red and blue star gemstones are the most valuable, and if the star line meets the above conditions and is more transparent, the value is very high. These two star sapphires of yours are obviously exactly the same as ...... No, it shouldn't be said to be out of the mark. ”

"Weigh one and weigh it. Tang Hao said, put the two star sapphires on the electronic scale and weighed them, and they were the same weight, both of which were 15 grams, which was converted to 75 carats.

"It's okay, it's okay. Tang Hao and Wu Lao breathed a sigh of relief, this kind of weight was not too exciting. Now treasured in the Museum of History in New York, the "Star of India" is a rare treasure with perfect starlight and no flaws, weighing 563 carats, which is much heavier. However, there is no doubt that this pair of 75 carats, more perfect star sapphires, is definitely worth a lot.

"Wait, I wondered what I was missing. Wu Lao's expression suddenly moved, and he took out a few small flashlights from his bag to irradiate them, and when he turned on the yellow light, the sapphire actually changed color and showed purple. When it is irradiated with ultraviolet light, it turns red again. Wu Lao was shocked again, "Oh my God, this is not an ordinary star sapphire, but a color-changing star sapphire." ”

Color change star sapphire accounts for a very small proportion in the star sapphire family, accounting for about one thousandth, the weight is generally not more than 3 carats, more than 5 carats is extremely rare, more than 10 carats is a gift from God.

In September 2013, a 67.98-carat star sapphire was designed and polished by Mr. Xu Lianfu, a famous gemstone design and cutting master, a famous gem collector and the inventor of Chinese diatom mud, after three months. This gemstone is the largest color-change star sapphire ever identified by GRS and has been named the "Violet-Blue Star". When it was released, it shocked the world.

And the two identical pairs of star sapphires weighing 75 carats in front of him turned out to be color-changing star sapphires. Tang Hao and Wu Lao were both heartbeating, blood and qi surging, and dizzy. (To be continued.) )
