Question: Information: - Gabriel S. '' Gabi '' Tolkowsky ( born 1939 ) is one of the world 's most renowned diamond cutters , the sixth generation of the Tolkowsky family to make his name in the trade . He is the great nephew of Marcel Tolkowsky , the father of the modern round brilliant diamond cut . - Diamond (or ) is a metastable allotrope of carbon, where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite, but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. In particular, diamond has the highest hardness and thermal conductivity of any bulk material. Those properties determine the major industrial application of diamond in cutting and polishing tools and the scientific applications in diamond knives and diamond anvil cells. - A diamond cut is a style or design guide used when shaping a diamond for polishing such as the brilliant cut. Cut does not refer to shape (pear, oval), but the symmetry, proportioning and polish of a diamond. The cut of a diamond greatly affects a diamond's brilliance; this means if it is cut poorly, it will be less luminous. - Marcel Tolkowsky (25 December 1899 10 February 1991) was a member of a Jewish family from Poland of diamond cutters and an engineer by education. He is generally acknowledged as the father of the modern round brilliant diamond cut. Many of his family have gone on to become noted diamond cutters, including his cousin Lazare Kaplan and his great nephew Gabi Tolkowsky. - Poland, officially the Republic of Poland, is a country in Central Europe, situated between the Baltic Sea in the north and two mountain ranges (the Sudetes and Carpathian Mountains) in the south.
