In China, the certificates issued are actually different from those tested by international standards. Foreign certificates are graded according to international standards. Sometimes, the same diamonds with international certificates are localized in China.
The quality inspection institutions in our country are strict in the first inspection and the national inspection, and diamonds with international certificates generally cannot reach the same grade in China. Even sometimes the appearance of human certificate makes the standard more vague.
is based on international standards, giving the original appearance of the diamond itself; Or must international standards be localized, so that the characteristics of diamonds themselves are "degraded by three levels"? For example, the standard on the book is the features seen under a magnifying glass of 1 times, and the quality inspection agency will look at it with a microscope of 2 times or a gem, and only those that cannot be seen by the microscope will be given a grade.
Gao De and the Federation of Industry and Commerce just don't have a "national prefix" and "royalty".
as for the price. As a consumer, you may regard a diamond as a wonderful thing, even if it is a "broken diamond". If there is no more than 1 carat, in fact, what is the preservation and quality, isn't that all nonsense?
may I ask the landlord, do you like things? Are you satisfied? Within the scope of economic commitment, it is ok. It's real. Quality, layman will never understand.
when will the jewelry industry, which I have loved since I was a child, be truly standardized, as beautiful as people expected and as dazzling as diamonds ~!
