Here are the core reasons why three cultivated diamonds are so difficult to buy?

The three core reasons why cultivated diamonds are extremely difficult to buy are mainly related to the loss of rough diamonds, the difficulty of cutting and rating, and the merchants 'inspection strategy. The details are as follows: The contradiction between the scarcity of diamond with an aspect ratio of 45-50% and the loss of the rough: If an oval diamond needs to reach an aspect ratio of 45-50%(such as 9×6mm), the diamond blank needs to be made Special cutting. However, such a ratio will significantly increase the loss rate of rough materials, resulting in a significant decrease in the utilization rate of raw stones.

It is understood that cultivated diamonds in Zhecheng, Henan Province will be sold cheaper. The main reasons are as follows: Industrial scale advantages: Zhecheng's annual output of cultivated diamonds exceeds 10 million carats, accounting for more than 60% of the national market share. More than half of the world's cultivated diamonds are produced Since here, a mature large-scale industrial cluster has been formed, diluting production costs.

According to our understanding, it will save more money to buy cultivated diamonds in Zhecheng, Henan Province. The specific reasons are as follows: Industrial scale advantage Zhecheng is known as the "Diamond Capital of China." Its annual output of cultivated diamonds reaches 12 million carats, accounting for more than 60% of the country's share. More than half of the world's cultivated diamonds come from here. Large-scale cluster production can equalize production costs and make terminal prices more competitive.

What does Diamond 2ex mean?

EX: It means that two of the cutting ratio, symmetry and polishing of the diamond have reached EX level. Although it is also a relatively excellent cut, compared with 3EX, it has one less EX-level performance. In terms of visual effects, although it is difficult to directly distinguish with the naked eye, if you use a fire color instrument to compare, you can see certain differences. Price difference: Due to the higher grade of 3EX cutting, its price is usually more expensive than a diamond ring of the same quality with 2EX cutting.

Diamond 2EX means that the symmetry and polishing degree of the diamond can reach the Ex (Excellent) level. The following is a detailed explanation of diamond 2EX: Symmetry Ex level: The symmetry of a diamond refers to the neat arrangement of the various cut surfaces of the diamond.

EX: Diamond ring 2EX means that the symmetry and polishing degree of the diamond can reach Ex (Excellent) level. This usually means that diamonds perform very well in both aspects, but it does not cover all aspects of cutting. 3EX: Diamond 3EX refers to the fact that the cutting and grinding of diamonds (including table width ratio, crown height ratio, waist thickness ratio, pavilion depth ratio and other parameters), polishing degree and symmetry can all reach the Ex level.

Conceptual meaning: "ex" is the abbreviation of "excellent" in English, which means perfect. 3ex means that the three attributes of diamond cutting: cutting, polishing, and symmetry are all perfect; 2ex usually means that cutting and symmetry are perfect, but polishing does not meet this standard.

1. Clarify the evaluation standard for cutting of shaped drills. Evaluation of non-cutting proportion of shaped drills: Different from the 3EX (cutting ratio, symmetry, polishing) of round drills, shaped drills are only rated by symmetry and polish., with a maximum of 2EX. If a merchant mentions "Shaped Diamond 3EX", it can be directly judged that it is not professional enough.

2. Symmetry and polishing: EX is best for symmetry, and EX is generally used for polishing. Reaching 2EX is a perfect oval cut diamond.

3. Select a standard shaped diamond cutter for a special shaped diamond cutter grade Polish polishing: Polishing will increase the brightness of the diamond.
