Basic Diamond Info

The "Four C's" of Diamonds

The 4Cs -Cut, Color, Clarity and Carat- are the 4 main aspects of a diamond's characteristics, and are considered the most important attributes to look for when choosing a diamond. The Gemological Institute of America is the creator of this international diamond grading standard. The diamond industry uses these four important diamond attributes to set universal standards for evaluating a diamond's quality, value, and beauty. If you are considering making a significant diamond purchase, you should definitely know what the 4C's are. Only purchase a diamond that is accompanied by a GIA Gem Trade Laboratory Report that accurately identifies the 4C's for that particular diamond. If you are seeking an ideal cut diamond, then request a supplemental Sarin Diamond Proportion Analysis Report from the vendor. Information provided by these reports is critical to making a sound and successful diamond purchase. Without it, one can easily overpay for the wrong diamond.
