The shape of diamond you choose for your jewellery is very much a matter of personal taste.
The traditional diamond shape is the round brilliant. It has 58 facets, or small flat polished planes, designed to yield the maximum amount of light to be reflected back to the viewer. As it is symmetrical and capable of reflecting nearly all the light that enters, it potentially has the greatest brilliance of all the diamond shapes. The most popular fancy shapes are marquise, emerald, princess, pear, oval and heart and Bill particularly enjoys creating designs featuring these more unusual diamonds.
