In addition, a modified Communication Slot II was present on the Power Macintosh G3 personality cards. The princess cut is also popular amongst diamond cutters: of all the cuts, it wastes the least of the original crystal. Buildings that are on preparation sites or ground works and have a planned height of at least 150 m (492 ft). Today, because of the relative importance of carat weight among buyers, many diamonds are often intentionally cut poorly to increase carat weight. The skill with which a diamond is cut determines its ability to reflect and refract light. Fire refers to the spectral colors which are produced as a result of the diamond dispersing the white light. Other colors diamonds can fluoresce are green, yellow, and red, but are very rare and are sometimes a combination of the colors such as blue-green or orange. Many large, famous Indian diamonds of old (such as the Orloff and Sancy) also feature a rose-like cut; there is some suggestion that Western cutters were influenced by Indian stones, because some of these diamonds may predate the Western adoption of the rose cut.

Several different theories on the “ideal” proportions of a diamond have been and continue to be advocated by various owners of patents on machines to view how well a diamond is cut. Proponents of these machines argue they help sellers demonstrate the light performance of the diamond in addition to the traditional 4 Cs. In the gem trade, the term light performance is used to describe how well a polished diamond will return light to the viewer. Scintillation refers to the small flashes of light that are seen when the diamond, light source or the viewer is moved. Brilliance refers to the white light reflections from the external and internal facet surfaces. The former refers to the class division emphasized by the “slot” and the latter by the dual identity of the protagonist, Freddie Drummond. Also in their class was chess grandmaster Bobby Fischer. The round brilliant cut is preferred when the crystal is an octahedron, slotdenganbonusbesar as often two stones may be cut from one such crystal.

19 April – Six soldiers are killed and two others are injured in an ambush during anti-bandit operations in Shiroro, Niger State. The prong setting consists of four or six ‘claws’ that cradle the diamond, allowing the maximum amount of light to enter from all angles, allowing the diamonds to appear larger and more brilliant. The quality of a diamond’s cut is widely considered the most important of the four Cs in determining the beauty of a diamond; indeed, it is commonly acknowledged that a well-cut diamond can appear to be of greater carat weight, and have clarity and color appear to be of better grade than they actually are. Four official reasons are given for ‘suspending work’. The setting diamonds are placed in also affect the performance of light through a diamond. Diamonds which are not cut into a round brilliant shape are known as “fancy cuts.” Popular fancy cuts include the baguette (French, meaning rod or loaf of bread), marquise, princess cut (square outline), heart, briolette (a form of the rose cut), and pear cuts. Oddly shaped crystals such as macles are more likely to be cut in a fancy cut-that is, a cut other than the round brilliant-which the particular crystal shape lends itself to.
