Center Stone Size

Nexus Diamond™ alternatives, like natural diamonds, are measured by carat weight. Unlike natural diamonds, the Nexus Diamond™ alternative costs up to 80% less than a mined diamond of comparable quality and weight. For reference, a 1.03 carat round brilliant stone is about the size of a pencil eraser.
