SORMUS, Peruzzi- ja 8/8-hiotut timantit, platinaa. A. Tillander, Helsinki.

Vincent Peruzzi, a Venetian polisher, later increased the number of crown facets from 17 to 33 (triple-cut or Peruzzi brilliants), thereby significantly increasing the fire and brilliance of the cut gem, properties that in the Mazarin were already incomparably better than in the rose.
