The search for the perfect cut diamond.
Historically, rough diamonds were cut ie faceted to preserve as much of the rough stone as possible. This led to diamonds of odd and strange shapes. The shape of a diamond is determined by the way in which it is cut and worked and finally polished. The early shapes of cut stones were simple. The shapes were restricted by the tools and technology of the time. As techniques, knowledge and tools improved the cuts became more and more complex. Over time cutters came to realise that a round shape diamond with a large top facet and several side facets gave most sparkle and fire. Over the years all this work and research led to the idea that there must be an ideal cut, that would produce a perfect diamond. In 1919. Marcel Tolkowsky developed a cutting formula for a round diamond. He cut diamonds to his mathematical formula, to precise angles and proportions which would give the best reflection and refraction of light. the proportions he used produced a truly beautiful diamond, which became the “modern brilliant cut”, originally known as the “American ideal cut”
Traditionally the basic diamond shapes were – point cut, table cut, old single cut, mazarine cut, Peruzzi cut and old European cut.
Today diamonds are sometimes divided into two groups, round and then all other shapes are known as “fancy”.
Also, there are basically three fundamental styles of cut on which all others are modelled. Firstly the brilliant-cut with 57 or 58 facets. Then there is a step cut, usually four-sided and elongated. Finally mixed cut containing a mixture of brilliant and step-cut facets.
Brilliant Cut
Brilliant Cut diamonds come in several guises, firstly and most importantly, round brilliant, then the others – oval brilliant, pear brilliant, marquise or boat brilliant, and heart brilliant, all have 57 or 58 facets.
