Liz (Burnett) Kuhns described a square brilliant cut (28 facets) by Dr Duncan Miller (whose studio is in Capetown, South Africa). The angle of this cut is based on the refractive index of a stone and the higher the refractive index, the more beautiful the cut. Miller explained, “The cut is characterized by triangular facets arranged in pairs of fans, with their focal points offset by 90 degrees on the crown and the base of a square stone.” The Southern Cross Cut is a registered design. Whereas the design originated in the southern hemisphere (and the crossing over of facets creates a perfect cross in the center of the stone), the name was decided upon to also signify a famous star constellation - used for navigation - that is called the southern cross.
