925 bracelets wholesale Factors that determine the price of colored gemstones: carat and clarity

’' te gönderildi Kingjy tarafından

We all understand that diamonds have the so-called 4C as the evaluation standard. Aslında, these four evaluation standards are the main factors that determine the price for all gems, but the 4C discussed in diamonds has a unique and rigorous evaluation standard. , But for colored gemstones, the evaluation criteria are slightly different.

karat

Karat (karat) is the unit of weight for all gems. Each carat is equal to 0.2 grams and is subdivided into 100 puan (Point). Elbette, the higher the carat number, the higher the price, but the relationship between the price of a gem and the number of carats does not increase in the same proportion, yani, the price of a 2 carat gem is not twice the price of a 1 carat gem of the same grade, but far more than twice. The above price is because the larger the rough gemstone, the rarer it is, and the greater the price jump.

Cleaness

The degree of cleanliness inside a gem is called clarity, which mainly depends on the amount of inclusions in the gem. The less the inclusions, the higher the clarity. Too many inclusions will affect the reflection of light, making the brilliance of gemstones have higher requirements for clarity than other colored gemstones, because the quality of light reflection has a great impact on the brilliance of diamonds. Fakat, for colored gemstones, clarity does not need to be excessively demanding. İlk önce, because colored gemstones are mostly colored due to the quantity of elements; secondly, the inclusion of colored gemstones is usually an important indicator of authenticity, because inclusions provide The best basis for identification of origin.
