Diamond Shape Guide

Diamond shape refers to the physical form or exterior shape of the stone. This is one of the largest decisions you will have to make when purchasing a diamond. The shape of a diamond is the most immediately identifiable feature to the naked eye.

Diamond Grading

When choosing a diamond, the 4C’s are a great place to start. It is a universal diamond grade that groups diamonds by their cut, color, clarity, and carat weight. These factors determine the diamonds overall value and appearance.

Guide to Lab Diamonds

Lab-grown diamonds are incredibly difficult to identify from one another. A gemologist with specialized training and specialized equipment is needed to distinguish these characteristics. The two characteristics that allow gemologists to distinguish between stones are related to how diamonds are made, yet they in no way affect the stone's quality. The purity, color, fluorescence, and sparkle of these stones are identical to those of their mined counterparts.

Diamond Certification

A diamond certificate, also known as a diamond grade, is when a diamond is sent to a third-party laboratory to be graded according to the 4C’s. Diamond grading was made uniform by GIA, the Gemological Institute of America, in 1953 when they developed the 4C’s: cut, color, clarity, and carat.

When buying a diamond that has been certified, it has been graded by a trained professional that was taught by a reputable laboratory, allowing you to shop with confidence that the diamond you are purchasing is what is stated to be.
