Buying GIA Diamond Rings Online

You can get a better deal on diamonds if you buy the best-value diamonds online. Online retailers carry GIA diamond rings that come with an appraisal report from the Gemological Institute of America that certifies the authenticity of the diamond and its value. Although there is a wide selection of these rings at a regular jewelry store where you can look at the ring and diamond as well as try it on, you have the advantage of a much larger selection of exotic rings and colored diamonds when you shop online.

To buy diamond rings HK online, you must have a basic understanding of the four Cs of diamonds to understand the descriptions that accompany the rings and loose diamonds. There are also online sites where you can buy EGL loose diamonds and those that have IGI appraisals. These certifications also adhere to international standards for the evaluation and grading of diamonds and are accepted worldwide.

The four Cs are the standards used to classify the diamonds used in GIA diamond rings and refer to the cut, color, clarity, and carat of the stone. Online retailers will have this information listed with the image of the diamond. The carat of a diamond is its weight and even the smallest gem has one carat.

There are various diamond cuts of GIA diamond rings, which are highly dependent on the shape of the rough diamond.

Eight-sided rough diamonds are generally cut into round diamonds where the table is shaped like an octagon. In grading and evaluating each cut, there are certain characteristics that gemologists will look for. A Marquis cut, for example, has 58 facets. A round cut also has 58 facets: 33 on the crown and 25 on the pavilion. In an ideal cut, there is no facet on the chop, reducing the number to 57. The evaluation of GIA diamond rings follows the American standard for diamond cuts.

In this standard, there are certain percentages and angles for each aspect of the diamond. Gemologists use a perfectly cut diamond as a comparison sample and, using precise instruments, arrive at an appraisal. Generally, four gemologists evaluate a diamond at different times. This ensures that your GIA jewelry or diamond rings have undergone a full study by an independent process.

Its name is not related to the diamond in any way during the entire process and gemologists only know it by a number. The only part of the process that gemologists can differ in is in determining the color of the diamond. Contrary to what most people believe, not all diamonds are transparent and most have a trace of yellow in color. When determining color, powerful microscopes are used and gemologists must come to a consensus on color.
