This restless quest to merge old-world artistry with modern sophistication reached its zenith with the Kotlar Cushion®. The Kotlar Cushion® was inspired by old-world nobility and given shape by the most advanced methods.
The elite artistry and craftsmanship behind each Kotlar Cushion diamond makes it worthy of the title “The world’s most brilliant cushion-cut diamond.”
It is modeled after the antique cushion cut favored by 19th century royalty and the legendary Second Star of Africa set in the British Imperial State Crown.
The diamond is cut to maximize fire, brilliance, and scintillation. This meticulous process gives shape to stones that sheer radiance with gentle, feminine lines and a fuller silhouette.
The Kotlar Cushion ® Diamond Features a Unique 61-Facet Cushion Cut Diamond
The Kotlar Cushion diamond features a unique 61-facet arrangement. It is fashioned with a specific formula of pavilion & crown angles, table percentages and ratios to maximize its fire, brilliance and scintillation. It ranges in color from D to K. Clarity ranges from IF to SI2, the size from 0.70 to 20 carats.
Each Kotlar Cushion diamond is a testament to the craftsmanship that birthed it. To further authenticate its luxurious provenance, each Kotlar Cushion diamond has a tiny inscription on it.

David Wiener, grandson of Harry Kotlar, went on a quest to find a diamond with superior brilliance. Unable to find such a gem, he decided to create one. Kotlar Cushion® continues the commitment to perfection established by Harry Kotlar in 1948.
