The Virtues of Diamond: A diamond octahedron was highly valued: "He who, having pure body, always carries a diamond with sharp points, without blemish, free from all faults; that one, as long as he lives, knows each day will bear some things: happiness, prosperity, children, riches, grain, cows and meat. He who wears [such] a diamond will see dangers recede from him whether he be threatened by serpents, fire, poison, sickness, thieves, flood or evil spirits."
Cleaving
Cleaving involves the removal of impurities or irregularities in the rough diamond. Using a second diamond or a laser, a groove is carved into the diamond along a plane of weakness. A steel blade is placed in the groove and a sharp blow is delivered which splits the stone. Cleaving requires particular skill; if pressure is applied to the wrong area or in the wrong direction, the diamond may shatter. Not all rough diamonds require cleaving or sawing - some diamond rough is well formed and is in ready-to-cut form.
The Hardness of Diamond: Diamond's supreme hardness was recognized: "The gems and the metals that exist on earth are all scratched by the diamond: the diamond is not (scratched) by them. A noble substance scratches that which is noble and that which is not; the diamond scratches even the ruby. The diamond scratches all and is not scratched by any."
Heart The ultimate symbol of love, the romantic Heart shape is a variation of the round brilliant cut diamond. Length to width ratio A heart-shaped stone is usually proportioned with equal length and width, approximating a ratio of 1:1. A length to width ratio of between 0.90:1 and 1.15:1 is preferred. The ratio should not fall below 0.80:1 or exceed 1.20:1
Diamond Polishing
Diamond polishing consists of two phases, crossworking and brillianteering. To give the diamond its finished look, it is clamped to on an armature above a rotating polishing wheel (scaif). Diamond dust on the wheel's surface grinds the diamond down to the desired angle. The scaif makes it possible to symmetrically polish all the facets of the diamond at angles that reflect the most light.
