Ideal Cut – The King of Cut
In 1919, mathematician Marcel Tolkowsky published Diamond Design: A Study of the Reflection and Refraction of Light in Diamond. In his paper, Tolkowsky described diamond cutting specifications that would maximize a diamond’s brilliance. His cut was the basis for what is now known as the Ideal Cut. For years, the Ideal Cut has been considered the most brilliant 58 facet cut.
A diamond sold as an Ideal Cut in today’s market usually falls within the ideal range. For instance, the table (top facet) is usually between 53% and 57% of the diamond’s diameter. There are many other things a cutter must consider when attempting to achieve maximum brilliance. Some of them are: crown angle, pavilion angle, overall proportions, girdle thickness, facet placement, facet shape, and more. Each of these measurements have their own ideal range. How they relate to each other also affects the overall brilliance. In other words, all ideal cuts are not created equal.
A well executed Hearts and Arrows Ideal Cut diamond is the most brilliant of diamonds within the ideal range. Hearts and Arrows diamond cutters spend much more time maximizing the brilliance and beauty of their diamonds.
