Choosing the right Diamond Size

Diamonds are measured in Carats which is actually a unit of its mass rather than it’s physical size. This does mean though the larger the diamond the larger the carat weight. If you are keen to have a larger looking diamond for your spend then the Round Brilliant cut will look larger at 1ct than a comparative Princess Cut stone due to its shape.
