1. The essence of blockchain is a specially designed database system, or a distributed data system. In this data system, it can store digital currency, intelligent contracts with more complex logic, and a wider range of business data. In the development process of blockchain, it has also experienced such a stage

blockchain 1.0, It is mainly based on digital currency, the representative of which is bitcoin
blockchain 2.0, and its main architecture is represented by Ethereum to support smart contracts
blockchain 3.0, which goes beyond the application of digital currency and finance, is widely used in other fields as a technology
to sum up, data scientists like blockchain technology.
2. It depends on what organization you are looking for. The higher the level, the higher the cost. There is also to see how many goods you have to identify. The unit price of one is not the same as that of one hundred or thousands. For one, the national inspection, 50 ~ 100, the other 50 or so, and the cheaper 20 or 30. But not all the appraisal institutions give the appraisal, some no matter true or false, do not give the certificate
3. The appraisal office in the county and city is generally about 50 to 200 pieces. If you have several pieces to appraise together, the price will be lower. In addition, it depends on where you are. If it's wholesale places like Guangzhou and Nanyang, the appraisal price is cheaper. Where are you?
4. After purchasing diamonds, many consumers will send them to authoritative institutions for reexamination to confirm the authenticity and quality of diamonds, such as NGTC, GIA, HRD, etc. many of them are more concerned about how much it costs to identify diamonds. Here is how much the diamond identification fees of several authoritative institutions are generally< br />

domestic diamond appraisal institutions

NGTC diamond appraisal

NGTC is also the national jewelry and jade quality center. The domestic diamond appraisal price is lower. Generally, about 100 yuan can be used for diamond appraisal, but it also depends on the size of the diamond. Generally, the larger the diamond is, the more appraisal fees will be charged

in addition, some people also said that there are two kinds of NGTC certificates: identification certificate (only responsible for identifying the authenticity of diamonds, not grading), grading certificate (big certificate and small certificate), and the fees are not the same. It is suggested to contact the agency directly for the specific fee standard of diamond identification< At present, GIA and gemmological College of America are the most authoritative diamond appraisal institutions in the world. According to the price list of diamond appraisal fees on GIA's official website, the bigger the diamond, the higher the appraisal fees. Among them, the common 30 point diamond appraisal fee is 59 US dollars (about 407 yuan), 50 point diamond appraisal fee is 64 US dollars (about 441 yuan), and 1 carat diamond appraisal fee is 110 US dollars (about 758 yuan)< br />
< (3) HRD certification is one of the most authoritative diamond certification documents in the world. Generally, HRD diamond color certification includes color description, color design and luminescence, It plays an important role in detecting whether diamonds are naturally colored or imitation diamonds

the fee charged by HRD for diamond identification is slightly lower than that charged by GIA, and the specific fee standard can be contacted with the official for detailed inquiry

through the above sharing of diamond identification fee standards of different institutions, we can find that GIA charges a higher fee for diamond identification, but as an internationally recognized authoritative certificate, GIA certificate identification results are more recognized by people inside and outside the instry.

total: 10850 yuan ~ ~ 11250 yuan
you only have the domestic identification certificate, which should be the bulk cargo. The price is slightly lower than 10850 yuan.
6. The appraisal of jewelry stores is not authoritative and may not be reliable, and the appraisal is even less reliable.

without this business, they are not responsible for what they say, so of course there is no charge.

the charging standards of appraisal centers are different, and they are generally slightly higher for indivials. In Beijing, the appraisal center appraises precious metals and diamonds, which is about 100 yuan

it's not troublesome, but it's not guaranteed that every company can give the identification results at that time. Some of them are just working places, without instruments. It takes at least three days for the identification to be taken back to the headquarters
7. Shopping malls and gold shops can only identify the authenticity of gold, but not the content of gold. Moreover, they have no authority in their identification, and you may not believe it yourself. I suggest the owner to go to the professional jewelry appraisal center. Can not find a place to call 114 inquiries, or call the Bureau of instry and commerce, many places do not charge fees, but still depends on the personal situation, I hope the landlord smoothly
8. If the identification of precious metals, such as the identification of types and contents, is relatively expensive, about 100 yuan per piece; If it is to identify gemstones, such as rubies and sapphires, it usually costs 100 yuan to have an instrument
for diamond identification, the small certificate is 30 and the large certificate is 100
if it's jade like jadeite, there are 10 small certificates and 100 large certificates.

this price is just a reference price, which varies from place to place, as well as businesses and indivials
9. A 100, if you still need to test Tuo, add 50, 3 working days to take, location in Beijing Xiaohuangzhuang, other places have not been to do not know, 22 points do not need to supervise, 20 points below only identify true and false, do not give specific data, more than 2 points, there is no need. 43 earrings, two diamonds 43 or a pile of broken diamonds 43? In fact, I don't think it's necessary to test it. Maybe what you buy is very expensive, but the actual value is not high.
