Hardness: The resistance of a substance to being scratched. Mohs scale of relative hardness consists of 10 minerals, each scratching all those below it in scale and being scratched by all those above it. Diamond is 10 on the Mohs scale of hardness, meaning that the only thing that can scratch a diamond is another diamond. Tests prove that diamond is approximately five to 150 times as hard as corundum, the next hardest mineral. Head: The metal basket which holds the diamond in place with prongs. The head is attached to the ring, earrings, pendant, etc. Heart Shaped Diamond: A fancy diamond cut, which is cut to resemble the popular Valentine's Day heart shape. It is a modified brilliant cut with a heart-shaped girdle outline that is similar to the Pear Shape Diamond, except that there is a cleft at the top. In fact, often the reason diamond cutters may choose a Heart Shape over a Pear Shape may be that the rough diamond contained an inclusion located in the cleft. The skill of the cutter can make a great difference in the beauty of this cut. Hearts & Arrows: A Round Brilliant Cut diamond that is cut and polished to ideal proportions with exceptional symmetry and polish which shows eight heart shapes (Pavilion view) and eight arrows (Crown view) when observed through a special viewer called a FireScope. There is no industry standard of diamond proportions. HRD: Hoge Raad voor Diamant (HRD).
