  2. Diamond cutting - Wikipedia

    en.wikipedia.org/wiki/Diamond_cutting

    Diamond cutting is the practice of shaping a diamond from a rough stone into a faceted gem. Cutting diamonds requires specialized knowledge, tools, equipment, and techniques because of its extreme difficulty. The first guild of diamond cutters and polishers (Diamantaire) was formed in 1375 in Nuremberg, Germany, [1] and led to the development ...

    en.wikipedia.org/wiki/Material_properties_of_diamond

    A scattering of round-brilliant cut diamonds shows the many reflecting facets. The luster of a diamond is described as "adamantine", which simply means diamond-like. Reflections on a properly cut diamond's facets are undistorted, due to their flatness. The refractive index of diamond (as measured via sodium light, 589.3 nm) is 2.417.

    en.wikipedia.org/wiki/Cut_(gems)

    The diamond cut planning stage is a complex process that requires the cutter to work with unique rough stones. Very often, the location of the inclusions in a rough stone will determine the type of shape to which a diamond may be cut. For economic reasons, most diamonds are cut to retain weight instead of maximizing brilliance. [2]

    A laboratory-grown diamond (LGD), also called a lab-grown diamond, [ 1 ]laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is created through geological processes and obtained by mining).

    Lodewyk van Bercken was a Flemish diamond polisher who invented the scaif. This ingenious polishing wheel enabled him to quickly cut facets into diamonds with precision. The scaif transformed the diamond trade. It opened the doors to the creation of complex diamond cuts which otherwise would have never been possible.

  9. Culet - Wikipedia

    en.wikipedia.org/wiki/Culet

During the 14th century, after the adoption of the table cut, a further facet was added to the bottom of the cut parallel to the surface of the table. The term used for these bottom facets derives from the Latin word for bottom, culus. The culet is added largely to protect ...
