Diamond Certification

When purchasing a diamond, it’s important to know your diamond’s certification. Both the Five Cs and the international grading system of diamonds were created by The Gemological Institute of America (GIA). They are believed to be the most reliable institution in the world when it comes to diamond certification. A certificate known as Gem Trade Laboratory (GTL) Report is issued by GIA to various jewelers, which quantifies the quality of the jewelry. They are well-versed in judging flaws, the Five Cs and the precision of a diamond’s shape. One of the top benefits of purchasing GIA-certified pieces is that they only grade natural diamonds. If a diamond is graded by GIA, you can be assured of its authenticity.

Many places offer a variety of other laboratory certifications, which might be more detailed, but it is best to stick with GIA, as they’re extremely reliable and have been in the industry for many years.
