Scaif
From Wikipedia, the free encyclopedia
Scaif is a polishing wheel infused with a mixture of olive oil and diamond dust used in the diamond cutting industry.
It was invented in 1456 by Lodewyk van Berken. With the scaif, it became possible to polish all the facets of the diamond symmetrically at angles that reflected the light best. This invention revolutionized the diamond cutting industry and correspondingly, the popularity of diamonds.
