A diamond certification allows the buyer to know that they are getting a high quality lab grown diamond of good value. This certification is issued by an independent gemological lab. It gives the buyer information on the diamond’s cut, carat weight, color, clarity grade, and more. There are a few laboratories that grade diamonds. But there is one lab that goes above and beyond the rest —GIA (Gemological Institute of America). Established in 1931, GIA is known to be the “gold standard” for diamond grading. Therefore, a GIA diamond is one of the best you can get when shopping for engagement rings.

What Are GIA Diamonds?

A GIA diamond is one that receives a grade from this independent laboratory. You may have heard about the 4 C’s of a diamond, but did you know the GIA invented this system? The GIA also invented the terminology for the grading system. Every independent gemological lab uses this grading system; jewelers and retailers alike trust it. 

GIA upholds the strictest diamond grading criteria in the industry. They were the first independent laboratory to introduce diamond grading reports in 1953, which are still in use today. They even graded the famous 45 carat Hope Diamond, a massive blue diamond currently on permanent exhibition at the Smithsonian.

GIA Diamond Graders Are Meticulous.

GIA does not certify diamonds. Rather, they grade them based on the diamond’s unique features. Saying that a diamond is GIA-graded means that it passed the strict examination of the GIA labs. GIA is an independent, nonprofit organization; it has no real say in a diamond’s certification or value. They only give a report on a diamond after evaluation. However, GIA graders are meticulous when it comes to grading color, clarity, cut, and carat weight. GIA will also grade a diamond on its fluorescence, finish, and any other data relevant to the diamond.

Is a GIA Diamond Worth More? 

Because GIA is the most respected lab, people think their diamonds are more expensive. However, this is false. Remember, GIA does not certify diamonds, they only grade diamonds. The value of a diamond is tied to its quality. A diamond of lower quality will be less expensive, and of higher quality will be more expensive. GIA provides these grading reports so the buyer knows if the diamond they’re buying is of good quality, and therefore value. This is why diamond grading is so important—it tells the consumer exactly what they are paying for. 

Do You Need to Get a Diamond Graded?

You should always receive a diamond certification when you purchase a diamond, online or in a store. The certificate is an identity card for your unique and precious diamond. It will show you all the qualities of that diamond. Also, this diamond certification is necessary if you plan to get jewelry insurance down the line. Remember that if you are purchasing a diamond, either online or at a store, you should receive a diamond certificate. Only purchase your diamonds from reputable brands, and be sure to do your research. This is a major purchase, be sure to do your due diligence before buying.
