Gemstones are a fascinating subject, and they are something that interest both collectors and scientists alike. For the most part, though, when people think of gemstones, they think of jewelry. Of course, when it comes to gemstones being used for jewelry purposes. there is no stone more quintessential than the diamond. Diamonds have drawn people’s attention for thousands of years, and their structure is something that even interests scientists. Their dense structure is what makes them so hard and nearly indestructible. In addition to being incredibly hard, they are also aesthetically pleasing, and they are something that every jeweler strives to keep in stock. The best quality diamonds are those that you can get from a reputable jeweler individually. These are called loose diamonds.
Loose diamonds come in countless different shapes and sizes, and they can vary in price so drastically, that there is really no way of knowing the value of a diamond, unless you have proper documentation. This is because the subtle nuances that make a certain diamond more valuable than another would be imperceptible to most people, unless they had gemological training. Luckily for those of us who are not gemologists, there is a system that helps people to know what a diamond is actually worth. While the system is universal, there is more than one institution that makes these ratings, and it is important to understand the difference between them. Of all the organizations out there making these determinations, there is definitely none better than the GIA, or Gemological Institute of America. GIA certified diamonds are essentially considered the standard just because the GIA is the most respected institution that makes these decisions. Many jewelers will not deal with diamonds that are not GIA certified.
As for the criteria that they all use to make the determinations, nothing about it is too complicated. There are four categories that are used to judge the diamonds, with the four together being known as the four “c’s” of diamonds. While no one category determines the value of the diamond, there are certain categories that people seem to pay more attention to than others. Carat may be the most important just because it has to do with the size of the stone. Larger diamonds are worth a lot more than smaller diamonds, at a rate which is not seen in the other categories. Color is another category of diamonds that is interesting because it is not always exactly on par with the value of the diamond. While diamonds without any color get the highest ratings, some diamonds that are certain colors are worth more money because of their rarity, even though they do have a lower rating in this category. Cut is the third category, and it is also strange, since it is something that is under the control of the human being who cut the stone in the first place. Finally, there is clarity, which is just how perfect the diamond is. Stones with few flaws are rated higher and are more desirable for engagement rings and other pieces.
