How to read a diamond: the 4Cs, the shapes, certification, and what we look for when we grade. When you are ready to compare, browse our [certified loose diamonds](https://diamonds.com.lb/loose-diamonds/) or see our [engagement rings in Lebanon](https://diamonds.com.lb/engagement-rings/), each made to order in Beirut.

> **Quick answer:** Before buying a diamond, learn three things: the 4Cs, where cut matters most; how each shape handles light and wears on the hand; and how to read a GIA or HRD certificate and verify its number on the laboratory's own website. These guides explain each one in plain language, then point you to real certified stones to compare.
