The perfect cut: Brilliants

Brilliant-cut diamonds, or 'brilliants', are diamonds in a special cut featuring a symmetrically circular girdle. Brilliants offer - as their name suggests - exceptional brilliance and sparkle, as the cut is designed to refract and reflect the light with the maximum effect.
