The color classification of GIA pink diamonds in the United States is as follows: weak pink, very light pink, light pink, lighter Pink (), normal pink, darker pink (), fancydeep and bright pink ()
the study of pink diamonds shows that nearly 1 / 2 of the samples studied have color bands, of which the color bands of type I pink diamonds are not more than 65%, and only 12% of type II pink diamonds have color bands
the purity of pink diamonds is almost irrelevant, which is completely different from the requirements of identifying and evaluating colorless diamonds. However, the results of pink diamond identification confirmed that 68% of type II pink diamonds were above vs. according to the test results of all samples, only 51% were pink diamonds with vs
when pink diamonds are irradiated with violet light (no matter long wave or short wave), most of them have no or little fluorescence effect. The color of pink diamonds can change during cutting and polishing
extended data:
diamond refers to polished diamond. Diamond is a natural mineral and is the original stone of diamond. In short, diamond is a kind of monocrystalline crystal composed of carbon element formed under high pressure and high temperature in the deep earth. Diamond is beautiful and rare. It is a symbol of love and loyalty and represents eternal love
1. Symbol of eternal existence: tens of millions of years ago, the hot magma in the deep underground rushed up along the hundreds of pipes. Because the crater was often blocked, the rising magma was cooled under extremely great pressure. A small amount of pure carbon contained therein crystallizes into diamond under such high temperature and great pressure
2. The symbol of pure love:
diamonds are pure and transparent, lasting. The diamond ring looks like a lover's bright eyes, and deeply VIP looks at you. It is the symbol of pure love and affection, which indicates the eternal pursuit and loyalty of love
The color classification of GIA pink diamonds in the United States is: weak pink (faint), very light pink (very light), light pink (light), relatively light pink (fancy light), normal Pink (fancy), darker pink (), dark pink (fancydeep) and bright pink ()

extended data:
about 90% of the red and pink diamonds in the world come from Argyle mine in Western Australia. Most of them are small particles - the average weight of Argyle pink diamonds is 1 carat
the mining area produces about 50 carats of pink diamonds each year, accounting for 0.0001% of the total diamond output. The rarity of pink diamonds in the mining area makes them widely cherished and pursued. Argyle holds a tender for its pink gems every year
although the Argyle mine is the main producing area of pink diamonds, the largest pink diamonds known today - some of the most famous diamonds in the world - are mined in other areas
the largest existing pink diamonds darya-i-noor (186 carats), Nur El AIN (60 carats) and Shah jahaan pink diamonds (56.71 carats) were all excavated in Kollur mines near Golconda in southern India several centuries ago
It can be identified with a thermal conductivity meter
there are four factors to evaluate the grade of diamonds, namely, color, clarity, cut and carat weight of diamonds
the grading standards of pink diamonds are: fine pink, light pink, fan light pink, fan pink, fan intensity pink, fan deep pink, fan vivid pink
every diamond contains natural inclusions, just like natural birthmarks. The number, size, shape and color of these inclusions determine the clarity and uniqueness of a diamond. The contents are hidden in the diamond and can be in different colors: white, black, colorless, even green or red. Most of the contents can not be discriminated with the naked eye, and can only be clearly seen under a 10x magnifying glass. Cleanliness is a grading system for measuring the number of inclusions and defects: from FL / if (perfect / internal perfect) to I (defective). Class I cleanliness means that the contents can be discriminated with the naked eye
The color classification of pink diamonds is - fault Pink (micro pink) - light pink (light pink) - fan light pink (color light pink) - Fan Pink (color pink) - Fan intense Pink (bright pink) - Fan deep pink (dark pink) - Fan vivid pink (bright pink) pink diamonds include: light purple pink - Pink - orange yellow pink. The cause of coloration of colored diamonds remains to be studied. Some studies believe that it is caused by the defects of diamond crystals, which is consistent with the cause of coloration of brown diamonds. The study also points out that pink diamonds include type I and type II. Among the 1490 pink diamonds measured in the study, 1166 are type I pink diamonds and only 324 are type II pink diamonds. That is to say, the proportion of pink diamonds in type I diamonds is large, while the proportion of pink diamonds in type II diamonds is small. However, the study also found that most of the type II pink diamonds have a large weight, while the type I pink diamonds have a small weight. That is to say, the pink of the diamond is not only related to the type of diamond, but also related to its weight. Different types of pink diamonds have different change rates of pink. The color classification of GIA pink diamonds in the United States is as follows: weak pink, very light, light pink, relatively light pink, normal pink, darker pink (), dark pink, and bright pink (). The research on pink diamonds shows that nearly 1 / 2 of the pink diamonds studied have color bands. Among them, the color bands of type I pink diamonds do not exceed 65%, and only 12% of type II pink diamonds have color bands the purity of pink diamonds is almost irrelevant, which is completely different from the requirements for identifying and evaluating colorless diamonds.

Diamond grading refers to the grading of diamonds from four aspects: color, clarity, cutting and weight, which is referred to as "4C" grading. Diamond grading is a comprehensive evaluation of the Gemological properties and values of diamonds 1. Color: the grader can divide the transparent and colorless diamonds in nature into several grades. The yellow the color, the lower the grade 2. Clarity is used to describe the obvious degree of internal and external defects of the diamond. The grader can't see the internal and external defects with a ten times magnifying glass, and the diamond is rated as flawless; A diamond with defects that can be observed by the grader's naked eye is classified as severely defective 3. Cutting refers to the grading of the cutting and grinding ratio and finishing degree of the finished diamond according to a certain cutting standard. The cutting and grinding ratio refers to the relationship between the size, shape, distribution and cutting angle of the facet. The finishing degree reflects the symmetry, polishing and other details 4. Weight is the most objective evaluation in the "4C" classification. The bare drill can be directly weighed and evaluated with a standard weighing instrument.
