  1. 0.028 and 0.207 are the weight of diamonds.
    The carat (CT) is the quality (weight) unit of gems, and 1 carat is currently equal to 0.2 grams or 200 mg. One carat is divided into 100 points, such as 50 points, which is 0.5 carats, to calculate a small gem. Because the density of gems is basically the same, the heavier gems, the larger. The larger the gem, the more rare, the higher the value of each carat.
    The public carat unit, that is, one carat is equal to 200 mg and was adopted since 1907. Before that, one carat was equal to 205.3 mg, which is 0.2053 grams.
    The expansion information:
    1 carat = 200 mg = 0.2 grams. In the old gem book, one carat is about 205.3 mg. If it is converted to the current carat, one carat must multiply 1.0265. Here is just a rough saying that the carat value in the old countries or regions is different.
    Diamonds with a weight of less than 1 carat usually use "points" as a measurement unit, 1 carat = 100 points. In the diamond certificate, the weight of the diamond is accurate to the third place after the decimal point.
    igi uses an electronic balance with an accuracy of 0.00001 carat, which is called accurate diamond weight. The diamond weight is recorded in the diamond appraisal report and accurately reaches two digits after the decimal point. So a 25 -point diamond weighs 0.25 carats. Diamonds of the same quality, the larger the weight, the more precious.

  2. Your diamond ring arms should also have accompanying stones, so the capital D0.207ct is the weight of the main stone. The lowercase D0.028ct is the weight of the auxiliary stone
