Pendeloque
Pendeloque (also Briolette ) is the Gemological trade designation for a faceted and in drop form polished gemstone . The term is derived from the French Pendule (pendulum). Other names are pear-shaped , pear cut , Birnkernschliff or pear-shape cut .
application
Pendeloquen (Pendeloken) is also the general name for hanging earrings and the hanger for chandeliers . In the Oeconomic Encyclopedia von Krünitz from 1773 to 1858 it is stated about this technical term:
“Pendeloque, everything that hangs down as hanging pieces of crystal on the candlesticks, little things on the watch chains, and rags that hang jokingly on the clothes.
Pendeloquen, pendulum tokens, are called by the stone cutters diamonds, which are pointed at the top but rounded at the bottom, and the good sides of which have gradual waste in order to be able to create the surfaces there. If the body is of this nature it is grinded, giving it a free play to be used in earrings. If the diamond brings with it an unsuitable pendulum point, it is used to create a brilliant. "
history
Around 1456 or 1476, the Flemish diamond polisher Lodewyk van Berquem is said to have discovered diamond grinding with the help of diamond dust. He is also said to have cut stones in symmetrical pear shapes called pendeloque or briolette. The Sancy made for Charles the Bold of Burgundy and the well-known Florentine are designed in the shape of a Pendeloque.
