"Zimbabwe green chalcedony? What kind of chalcedony is that?"

Song Tao's overall gemology knowledge has reached the level of research. Logically speaking, the categories of mainstream gems should be impressed, but he has never heard of this kind of Zimbabwe green chalcedony.

"Master, can I take a look at your chalcedony?" Song Tao wanted to observe them up close.

The stall owner saw that Song Tao was Zhao Yichen's friend, so naturally there was no reason to disagree.

Song Tao picked up a chalcedony pendant and looked at the light on the roof. He was surprised to find that the interior was uniform in color and did not find any traces of the expected dyeing.

Song Tao picked up other chalcedony to check and found that there were no traces of staining in all chalcedony. He frowned and said, "Most of the green chalcedony currently dyed with inorganic chromium salt. It would be great if there was a Charles color filter."

The Charles color filter is a lens that can only transmit red light and part of yellow-green light. It can be used to identify various jades dyed with chromium salt. However, Song Tao cannot bring all kinds of portable identification equipment with him once he goes out.

Although there is no way to use professional identification instruments for measurements for the time being, Song Tao knew that Zhao Yichen should not deceive him. This kind of chalcedony color is probably natural.

Thinking of this, Song Tao stroked these small chalcedony stones and felt a storm in his heart. If these green chalcedony in front of him were really natural, they would shine in the future jewelry market.

Among natural jade, green is a very rare color. Why is imperial green jade the king of jade? It has a dark green that cannot be replaced by any gem.

In contrast, the green of Hotan Jasper is too deep, and the green of Australian chalcedony is too bright and shallow, so both of these jades cannot shake the status of green-toned jade.

Although the color of this Zimbabwean green chalcedony is still not as stunning as the Emperor Green, it is not far from that. Once it enters the market, it will inevitably bring a structural impact to the jade consumer industry.

Song Tao thought for a while and asked Zhao Yichen: "Where can you buy this kind of green chalcedony besides this?"

Zhao Yichen smiled and said, "It should be impossible to buy it, because the ownership of this green chalcedony in all mining areas in Zimbabwe has been acquired by our Yunshi Group."

After hearing Zhao Yichen's understatement, Song Tao was stunned for a long time, and finally breathed a sigh of relief: "This is really a mine at home."

Since all the mining areas of Zimbabwe's green chalcedony have been acquired, Song Tao also knew that this variety might be exclusively launched by Yunshi Group in the future, so he asked: "Have you thought about how to promote them?"

After hearing Song Tao’s question, Zhao Yichen rarely showed a worried look: “Not yet, the current national industry standard stipulates that even if the chalcedony is dyed, it can be considered purely natural.”

"That is to say, now they are sent to any appraisal agency, and the results are the same as those of dyed green chalcedony, and they are just natural chalcedony."

Song Tao nodded and said, "This is a little similar to the relationship between Xinjiang materials and Russian materials Hetian jade."

Song Tao naturally knew what Zhao Yichen said. Since the staining of chalcedony is so common, the current national industry standards do not require an appraisal agency to detect whether chalcedony is stained, as long as the stone itself is natural.

Thinking about this, there are indeed many imperfections in the current industry standards. With the development of the jewelry market and the continuous discovery of new mines, the standards must also keep pace with the times to better contact the current situation of the industry.

But Song Tao is definitely not qualified to do this kind of thing now.

Zhao Yichen paused and continued: "Actually, our company has contacted you, Huachang Dida, Gem and Gem Quality Inspection Center, and asked them if they could propose to modify the relevant regulations on chalcedony at this new industry standard setting conference."

Then she sighed and said, "Even if we promise to provide 30 million yuan in scientific research funds from these three institutions every year, the answer we got is still no."

Song Tao comforted: "The revision of industry standards is of great importance. Once there is a problem after the revision, our three institutions must bear the corresponding responsibilities, so we must be conservative on this issue."

In fact, what Song Tao said was only one of the reasons. He was very clear that the formulation of industry standards should take into account the overall interests of multiple aspects, and the game and interests in this were of great significance.

However, now there are only three months left before the industry standard setting conference is held, and Yunshi Group cannot convince the three major institutions to modify the industry standards, so it may have to wait a few more years.

At this moment, Song Tao for some reason suddenly remembered the large amount of scientific research funds donated by Sugut Group to the three major institutions every year.

So Song Tao pretended to be careless and asked: "Do you know the Russian Sugut Mining Group?"

"Of course, you can't be familiar with it anymore." Zhao Yichen nodded and said

"We have competitive relationships with Sugut Group in many mining areas abroad, but Sugut's size is too terrible. Even if Yunshi Group is a small figure compared to them, we are just one of Sugut's many competitors."

"So you have a competitive relationship with the Sugut Group?" Song Tao said in surprise.

He never expected that he would ask about this relationship just now.

In this way, the three major institutions donated by Sugut naturally cannot accept donations from companies that compete with it, which may lead to an embarrassing situation that is not satisfactory on both sides.

At this time, an idea suddenly came to Song Tao's mind: If Huachang Dida accepts 30 million yuan of funds from Yunshi Group and promotes the inclusion of chalcedony staining and identification into industry standards, wouldn't it be more confident to implement the idea of ​​"rejecting donations from Sugute Group and promoting the inclusion of Hetian jade production appraisal into the industry standards"?

But this idea is of great importance, and Song Tao did not say it rashly to Zhao Yichen.

Zhao Yichen seemed to feel that there was no need to continue discussing the issue of revising industry standards with Song Tao. After all, things that cannot even affect Yunshi Group, in her opinion, Song Tao is even more unlikely to do.

So Zhao Yichen changed the subject and talked to Song Tao about his daily life and academic affairs.

"You are now the team leader of the quality inspection station. What are you busy with now?"

Song Tao smiled and said, "There is nothing to be busy with. The usual work tasks are relatively simple for me. At this stage, I mainly work hard to apply for an intermediate professional title through a special talent plan that has just been promulgated."

Speaking of this, Song Tao breathed a sigh of relief and said a little tiredly: "I still need to publish two papers in SCI District 2 to be qualified to apply, but these two papers are still unclear."

"SCI?" Zhao Yichen thought for a while and said, "Can I give you a ready-made topic?"

Song Tao was shocked and asked, "What topic?"

Zhao Yichen picked up a Zimbabwe green chalcedony pendant and said, "We have just shipped this new chalcedony ore and has not been identified by any authoritative organization. You can take it to the quality inspection station for color research."

"It should be easy to discover and study a new variety of gems and post a SCI Zone 2."
