Do lab-grown diamonds have to be cut?
After the rough is made, lab-grown diamonds are cut and polished in the same way that natural diamonds are.

Can lab-grown diamonds be Coloured?
Lab-grown diamonds have nearly the same physical and optical properties as natural diamonds. They are just as hard and are available in nearly as wide a range of quality and colors. … Pink and blue lab-grown diamonds can sometimes have slightly different coloring than natural pink and blue diamonds.
Are lab diamonds enhanced?
Diamonds are strong, but the glass-like piece that has been added to clarity-enhanced diamonds is not as durable and can break or get damaged. On the other hand, lab engineered diamonds are grown to perfection and precision. They do not need treatments for enhancement.
