What Are Rough Cut Diamonds?

Rough cut diamonds, also known as uncut or raw diamonds, are stones that haven't been changed or polished after they're found. They have a different kind of beauty because they're in their natural state. They're still graded on the same things as other diamonds, like carat, color, clarity, and crystal structure. But the thing that makes them special is they're raw and untouched. It takes a skilled craftsman to turn these stones into the shiny diamonds you see in jewelry, but a lot of designers actually prefer to use rough cut diamonds because they love their natural look.

At A.A. Rachminov, we're experts at cutting diamonds, including white and colored diamonds, into all kinds of shapes and sizes.
