Diamond Cut: From Tolkowsky's Revolution to Modern Brilliance
Diamonds' brilliance and fire depend on their cut, one of the 4Cs determining their quality. Marcel Tolkowsky revolutionised this with the modern round brilliant cut, optimising facets and symmetry for maximum sparkle.
Tolkowsky's method, using mathematical precision, created the standard 58-facet brilliant cut, including a culet. This cut, now common, maximises light reflection within the diamond. Laboratories grade cut quality for brilliant stones.
Historically, diamond faceting began with replacing a corner of an octahedral crystal with a table facet. Over time, styles evolved. The princess cut, for instance, enhances brilliance in square to oblong stones. Efforts are underway to incorporate observer perceptions into cut quality assessments, making grading more subjective.
The cut of a diamond significantly impacts its beauty and value. From the original brilliant cut to modern styles like the princess cut, each design maximises a stone's brilliance and fire. As cut quality assessment evolves, diamonds continue to captivate with their sparkle.
