Diamonds purchased through ECI Jewelers are accompanied by their original certificate, also referred to as a Diamond Grading Report, Diamond Dossier®, or Diamond Quality Report. ECI Jewelers provides free appraisals for all engagement rings, Design Your Own rings, and all gemstone jewelry valued over $500.

WHAT IS A CERTIFICATE?

A diamond certificate is prepared by an independent third party laboratory and verifies that a diamond is genuine and provides an evaluation of a diamond's characteristics. A certificate will contain a complete quality description of the diamond and will include information on shape, weight, color, clarity, fluorescence, measurements, proportions and overall finish.

CERTIFICATES AND DIAMOND GRADING LABS

ECI Jewelers diamonds are graded by the two most reputable and respected laboratories in the industry, the Gemological Institute of America (GIA) and the American Gem Society Laboratories (AGSL). For your peace of mind, every loose diamond sold by ECI Jewelers has been thoroughly analyzed and graded by either of these independent laboratories. These two laboratories have demonstrated a long history of strict, consistent, and unbiased diamond grading.
