Whenever you are buying jewelries or loose emeralds online, quality should always be the primary thing that you must have in mind. This is because the quality of the item that you will get dictates the price or cost that you need to pay for. Aside from that, this is also your basis in determining its relative value compared to other gems. In this light, there are various ways on how we can judge the quality of emerald jewelries. Two (2) of the most common classifications are the AA versus AAA standards and the natural versus lab-created gemstones, aside from grading certifications.
AA versus AAA Quality Standards
The AA and AAA quality standards are, in fact, just among many ways to grade gems like loose emeralds. Firstly, AA refers to the quality of the gems with negligible inclusions, which are visible to the bare eyes. It also has no white spots and other flaws on the table. Hence, what this means is that the table of the gem is generally high qualiy, but there could be some tiny cavities on its crown. The AAA, in contrary, refers to a higher quality since it is characterized as flawless. Among the laboratories that do the grading is the European Gemological Laboratory (EGL).
Naturally-available Versus Lab-created Gemstones
Another way to describe the quality of loose emeralds online is to determine whether it is naturally-available or a lab-created gemstone. Generally, a naturally-available gemstone is characterized as something raw and exotic. Most of these are also difficult to retrieve or mine. Hence, they tend to be more expensive than the lab-created ones. Some of them could have some flaws, but could be enhanced to a perfect grade. The lab-created gemstones, in contrary, are those that are perfectly polished. Since they can be easily done through laboratories, they are more affordable than the other one.
Other Grading System of Various Laboratories
Moreover, aside from the first two (2) quality systems mentioned above, there are also various organizations that provide grading certificates to gems like those emeralds and even diamonds. When you buy loose emeralds online, you need to make sure that the gem has certification from any relevant organizations. Among the most common certifying bodies include the Gemological Institute of America (GIA), International Gemological Institute (IGI), Diamond High Council, which is the counterpart of GIA in Europe, as well as the Precision Gem Grading Laboratory (PGGL) in the state of Philadelphia and the American Gem Society (AGS).
