Diamond Evolution Collection


Replica, Diamond Evolution Collection
This is a set of 14 replicas showing representative diamond cutting styles since 1200 A.D. consisting of:


      Cubic Crystal – Always found unpolished

      Dodecahedral Crystal – Found both unpolished and naturally polished

      Octahedral Crystal (Point Cut 55°) – Naturally found with side angles of 54.74°. Frequently found polished or with a high luster. This is the most commonly found form from the ancient Indian deposits.


      Point Cut 45°, 50°, 60°, 13th C – The three point cuts were the first to be created by altering original octahedral crystals

      Table Cut without culet, early 14th C – Formed by removing the damaged top of an octahedral crystal

      Table Cut with culet, late 14th C – The culet facet was added on the bottom to remove damage and then found to improve optics


      Single Cut, late 14th C – A table cut with facets added at the corners

      Mazarin Cut, early 17th C – More a style than a specific cut, experimentation with angles and proportions begins

      Peruzzi Cut, mid 17th C – Again, more a style than a specific cut, this cut doubled the number of crown facets

      Old Mine Cut, 18th C – The old mine cut is the earliest form of the brilliant cut diamond. Also called the cushion cut.

      Old European Cut, 19th C – Another type of brilliant characterized by a large table, an open culet, and a round shape

      Modern Brilliant Cut, 20th C – The modern round brilliant cut was developed by Belgian diamond-cutter Marcel Tolkowsky in 1919. This cut is also known as the Tolkowsky cut and Tolkowsky brilliant.




This collection starts with the cubic, dodecahedral, and octahedral diamond crystal shapes as the stones came out of the ground. Over time, cutters learned to grind away surface damage and imperfections, leaving flat spots (facets) that dramatically improved optics and appearance. The laws of optics were not quantified until the early 1700’s, so the cutters had to experiment and use their intuition to see what worked and what did not. They didn’t know why facets changed the appearance, they just knew that there were changes. Over the centuries, they continued experimenting with different facet patterns, proportions for the table and culet facets, and facet angles to create the early works of art such as the Florentine (cut ~1500), Wittelsbach (prior to 1565), Sancy (~1400), and many of the other historic diamonds. In the early 1700’s, science eventually overtook intuition as they learned about the mathematical relationships between reflection, refraction, dispersion, and other optical properties, eventually resulting in the round brilliant cut of the 20th Century. This collection shows the progression of their experimentation, exactly what a diamond cutter saw and what they were thinking, allowing you to literally get into the minds of cutters that lived hundreds of years ago.
