Independently Certified

Every diamond, whether it’s lab-grown or mined, goes through the exact same certification process to ensure you’re getting exactly what you pay for. While there are several different independent, internationally recognized laboratories who issue certifications, the evaluation process across them is uniform and objective.  Regardless of the lab, every diamond is graded individually by several gemologists. Scores are then compiled to determine the diamond’s final classification. Although every gemologist adheres to the same criteria and standards, it’s not unusual for a diamond to receive a variety of grades—even if it’s sent back to the same lab for a second grading.  These standards are referred to as the 4C’s — cut, clarity, color, and carat. Gemologists will evaluate how well the diamond was cut from its raw form, how internally and externally flawless it is, how clear it is and how much it weighs.  Once the diamond has been evaluated, the lab will compose a full report, detailing each quality and providing a visual “map” of the diamond. This map illustrates any inclusions or blemishes found inside and/or on the surface of the stone. This report also includes your diamond’s unique identification number. Every Great Heights center diamond has its identification number inscribed on its girdle. This microscopic laser inscription can only be seen under magnification and doesn’t impact the beauty of the diamond in any way. It’s our way of giving you additional peace of mind; you’ll rest assured knowing that the stone you purchase is the same one you’ll receive—and proudly display for a lifetime together.
