Diamond Shapes

Diamonds are available in a variety of fancy shapes, typically describing the shape as if you were looking down onto the top of the diamond. The properties of the rough diamond will often have a hand in determining what shape the polished diamond will become. For example, rough diamonds that are less uniform are typically made into fancy shape diamonds, while rough that is more uniform is often cut into round diamonds.

There are no universal cut proportions for fancy shape diamonds. Forevermark has established our own proportions parameters to ensure each Forevermark fancy shape diamond looks truly beautiful.
