The Scissor Cut

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

It is not always easy to choose the best name for a particular cut from the variety of names given to it in diamond literature. The term Cross Cut has been quite widely used for design which I prefer to call the Scissor Cut. Cross Cut is unfortunate for two reasons: first, because it does not look like a cross, and secondly because the term ‘cross work’ is used today to describe the placing of the table, culet and first four main facets on the crown and pavilion. This preparatory operation produces what used to be called a Table Cut but is now termed a ‘four square’ or ‘cross’. More elaborately faceted Scissor Cuts have sometimes been given fancy names such as Maltese Cross (there is a variety in which the cross can actually be seen). To avoid confusion, I hope that the term Scissor Cut will eventually be accepted everywhere and for all gems.

In the case of diamonds, this cut dates back to the early sixteenth century; it gradually vanished in favor of the Brilliant Cut into which most Scissors had been fashioned by 1700 or so. It is logical to assume that the Scissor Cut originally developed from Pyramidal Cuts with trihedral faceting; the apexes of these obsolete Gothic cuts were replaced by table facets, very much in the way in which French Cuts were created from spheroid crystals.

No significant references to the Scissor Cut have so far been found, either in inventories (in which they appear to have been described simply as Table Cuts or ‘faceted diamonds’), or in diamond literature or old pattern books. The low-relief faceting of the Scissor Cut could not improve on the light effects of a Table Cut, so the design was soon abandoned. But it was gradually adopted for colored gems such as beryls, quartzes, etc., whose lower refracting power favored such faceting. Caire recommeded the Scissor Cut for purple and violet sapphires.

All the Scissor Cuts in designs by, for example, Morison, Albini and Dinglinger were large, and none is believed to have been a diamond. Fortunately there are a number of Scissor Cut diamonds in authentic jewels in the Schatzkammer der Residenz in Munich. They are quite small and therefore insignificant as jewels, but are interesting from a historical point of view. There are almost one hundred Scissor Cut Hogbacks (some of them flat-bottomed) on the heraldic double crowned eagle in Anne of Austria’s collection, dating from about 1550. On the splendid necklace acquired by Duke Albrecht V in about 1575 there are two tiny square Scissors. There is also one on hand seal made around 1690 and later owned by the Empress Amalie, daughter of Joseph I. She married Charles Albert, who became Emperor of Germany in 1742.

In the Cheapside Hoard (found in 1913 under a house in London) is a 3ct Scissor Cut. The cut, with two distinctly blunt corners, is rather poorly proportioned. Most disturbing is the incongruity of both the table and the culet. The stone measures about 8.4 x 8mm. It is set in an enamelled finger ring and apparently dates from the sixteenth century. The ‘scissors’ are in very low relief and not easily discerned.
