How to Read a GIA Diamond Certificate
Your fourth step in finding the right diamond is to go beyond the 4 Cs and learn the important details about certified diamonds and GIA diamond certificates (or Diamond Grading Reports as they are technically called) -- so you can compare any two diamonds accurately. The price of a diamond is in the details, so this is more important than it seems.
Read the articles you need below and ask your jeweler any questions you have, or use the orange box in the upper right corner of this page to contact me.
