Intricate science

There is an intricate science involved in cutting and polishing a rough diamond directly from the mine. The cut of a diamond refers its proportions and the quality of its clarity. The beauty of a diamond lies in its complex relationship with light where a perfectly cut diamond catches the light in a very particular way making it sparkling and radiant.

The cut also refers to the diamond’s shape and faceting, whether that is round, emerald, princess, pear, marguise and cushion cut, among others. A diamond can be brilliant cut, with triangular or kite shaped facets radiating from the center, or step cut, with long, slender facets in parallel rows. The most common cut is a round brilliant cut, with the diamond having 57-58 individual facets.
