By Amanda L. Colborn One of the most popular and consistently trending diamond and gemstone shapes is the cushion cut.

So fancy!

By Alethea Inns, CG Did you know that diamonds aren’t just round?  They are cut in all shapes and styles to suit any personality or occasion.

Considerations Cutters Take When Shaping Diamonds

Today’s blog post is written by American Gem Society member, By Marc Nanasi, from NEI Diamond professionals swear that Cut is the ‘C’ which has the most influence on a diamond’s beauty,and interestingly enough, it is also the only C that is controlled by humans (a diamond’s color, carat weight, and clarity are dictated from the rough stone found in nature).
