Human beings have been fascinated by diamonds for thousands and thousands of years, and they have been a part of the jewelry world for quite awhile. There are many reasons you can point to as to why diamonds became the most significant gemstone, but at this point it is clear that they are. Today, most diamonds that are not destined to be drill bits or saw blades end up becoming loose diamonds. Loose diamonds are diamonds that are cut and polished yet have not been made into a piece of jewelry at this point.

There are many places that sell loose diamonds, but it is important to be a savvy shopper, when it comes to purchasing them. Because they are such an expensive and sought after commodity, there is a lot of money to be made, in the industry. That is why it is necessary to research how diamonds are rated and priced before you buy anything. There is a pretty standard and established method for making the determination as to the value and quality of any particular diamond. And luckily, there is a clever little device for remembering the criteria: the four c’s of diamonds. If you have not heard of this before, do not fear. It is easy to understand.

  1. Carat: Carat is the first category by which diamonds are rated, and most of us have heard this term before. The carat is just how big or little the diamond is, with big diamonds having a higher numerical rating.
  2. Color: Color is, at the risk of sounding repetitive, the hue or color of the diamond. Because clear diamonds are the most desirable, lack of color warrants a higher rating than color, but there are some colorful diamonds that are worth more, due to their extreme rarity.
  3. Clarity: Clarity is the amount to which you can see into the diamond. If your diamond does not have very many flaws, you should be able to see inside it. It should be basically transparent, and so these diamonds get the highest clarity rating.
  4. Cut: Cut is a tricky one, since it is not a result of the natural formation of the diamond, and it is actually completely in the hands of whatever human being cut it.

Finally, you should not take all rating institutions at face value. GIA certified diamonds are definitely the ones that have the most credibility. The GIA, also known as the Gemological Institute of America, is the number one institution in the world of diamond ratings, so it is important to clarify that it is in fact that standard they are using. There are other organizations that do basically the same thing, only not as well. Because of this, their ratings do not carry all the same weight that GIA certified diamonds do. This is why if you are looking for loose diamonds for engagement rings, it is always necessary to make sure that your retailer knows about the importance of GIA certification, when it comes to diamonds.
