A rough diamond resembles an ordinary pebble. Many people would not give it a second glance. Only experts are able to reveal the glowing splendour of a diamond. Diamonds loose on average half of their original weight during the cutting process.
Diamonds derive their brilliance from the reflection of light. Our cutters must therefore fashion the facets (surfaces) in such a way that the maximum light is reflected between facets. The quality of the stone and the cutting process determine the price of the finished diamond.
Olive oil
Polishing takes place on a cast-iron disc. The latter is impregnated with olive oil and diamond powder. Thanks to the olive oil, the diamond powder enters the pores of the disc, making it sufficiently hard to allow polishing of the diamond, the hardest natural product.
The proportions between the top of the diamond (crown), the underneath (pavillion) and the flat surface of the stone (table) determine the brilliance of the diamond. An expertly cut diamond governs the polishing and therefore the brilliance and the ‘fire’ of the stone.
