Adding to this dazzling family this season is the Tiffany Novo which boasts a modern diamond cut and setting that redefines traditional taste with a striking newness.

Trielle Diamond
Trielle is a patented triangular brilliant cut diamond that differs substantially from any other triangular diamond on the market. (United States Patent D250,100). Every Trielle diamond is an equilateral triangle that is cut with 50 facets - 41 (including the table and culet) plus 9 girdle facets. Trielle diamonds are cut from rough diamonds called macles - hard, flat, often triangular-shaped rough diamonds which usually contain a twin crystal. Because of the many irregularities in the graining of this type of rough diamond, a high degree of cutting expertise is required. The pavilion angles are cut first to shape the rough diamond and create depth. After the pavilion angles, the crown facets are cut and the proportions of the table are determined. The girdle facets are then polished making sure that the resulting shape is a perfectly equilateral triangle. The table and culet are polished last to ensure that there are no scratches or bruises on the stone before the final step. The final step is called brillianteering. It is in this final step that the accuracy of cutting is most crucial. At this point each facet is formed symmetrically-one facet in relation to another. Certificate of Authenticity.
