The carat weight
The carat is a unit of weight. It originates from the orient, where, in ancient times people used carob seeds to weigh precious stones.
This has been popular for more than a century. Cushion-cut diamonds have rounded corners and large facets to emphasise their shine. These larger facets highlight the diamond’s clarity, so if you choose a diamond with an SI clarity rating, don’t forget to consult the plotting diagram in the diamond’s certificate. Cushion-cut diamonds are available in many shapes from square to rectangular.
