Two Unique, Trihedrally Faceted Point Cuts

(via Diamond Cuts in Historic Jewelry:1381-1910) Herbert Tillander writes:

There is also a historical diamond ring in the Hermitage, St Petersburg, similar to the Dresden ring. The diamond is almost as high, but the pavilion is deeper and the crown is trihedrally faceted. It is also much larger than the Dresden diamond, weighing well over 9 ct and measuring 11.5 x 11.5 mm.

On top of the crown of the pendant known as the Palatine Lion (in the Schatzkammer der Residenz, Munich) is the only surviving pyramidal diamond with trihedral faceting applied on eight, initially bruted, basic faces. Time and again we find such examples of early cutters’ incredible skill and imagination. In this case we can count twenty-four regularly formed and arranged facets on a space of 5 x 5 mm. The diamond is on the top of the lion’s crown.
