ROYAL ASSCHER, a diamond jeweler founded in Amsterdam, Netherlands in 1854, will begin releasing new diamond jewelry for the 2021 Autumn/Winter season on October 1, 2021, including the ROYAL ASSCHER SIGNATURE CUT collection, which features four original cuts that have been internationally patented. In addition to the square-shaped Royal Asscher Cut and the Royal Asscher Brilliant Cut, which are already available in Japan, the new Signature Cut collection will include the Royal Asscher Oval Cut and Royal Asscher Cushion Cut. The Asscher family's desire to make diamonds shine most beautifully, a passion that has been passed down since the company's founding, has been pursued in a variety of cut shapes. 
 
These cuts, which focus on a 74-facet shape, have the same number of facets as the Cullinan I and Cullinan II, which were cut from the world's largest rough diamond, the Cullinan, a legendary diamond that remains in the hearts of many people today and is set in the British Royal Scepter and the British Imperial State Crown. As the first step, a diamond ring will be released this fall, with plans to expand into a variety of other items such as pendants and bridal rings.
 
ROYAL ASSCHER SIGNATURE CUT COLLECTION
ROYAL ASSCHER CUT DIAMOND RING
Royal Asscher Cut
In pursuit of even greater brilliance than the 58-faceted "Asscher Cut," developed in 1902, Edward Asscher, the fifth generation of the family, successfully developed the 74-faceted "Royal Asscher Cut" in 2000, nearly a century later, through repeated research and refinement. Cut using only carefully selected regular octahedral rough stones, the "Royal Asscher Cut" is particularly known for its exquisite beauty of light created by the straight lines characteristic of step cuts and its high transparency. The beautiful curves of the two connected arms that gently open towards the center diamond, combined with the square-shaped main stone, create a design that is both elegant and refined.

ROYAL ASSCHER BRILLIANT CUT DIAMOND RING
Royal Asscher Brilliant Cut
 
An original 74-faceted cut with 8 facets added to the crown and 8 facets on the pavilion of the traditional 58-faceted round brilliant cut, for a total of 16 facets. The Royal Asscher Brilliant Cut, which achieves a deep and intense brilliance, is characterized by its fusion of white light brilliance and sparkling sparkle. The "halo" design, which enhances the brilliance of the center stone through a synergistic effect with the surrounding melee diamonds, further accentuates the brilliance of the center stone. The two layered arms set with melee diamonds add a touch of glamour to the woman wearing it.

ROYAL ASSCHER SIGNATURE CUT COLLECTION
ROYAL ASSCHER CUSHION CUT DIAMOND RING
Royal Asscher Cushion Cut
 
 
Developed in 2016 by father-son duo Edward and Mike Asscher, the fifth and sixth generation, the Royal Asscher Cushion Cut was inspired by the "Cullinan IV," the cushion cut set atop the "Granny's Chips" brooch, a British Royal Treasure worn by Queen Elizabeth II.
The two men researched all literature on "Cullinan IV" and refined the old diagram, first the pavilion side and then the crown side. By precisely adjusting the length of the pavilion facets, they were able to maximize the ideal light reflection.
The Royal Asscher Cushion Cut adds 20 facets to the standard 54-faceted cushion cut, adding 8 facets to the crown and 12 facets to the pavilion, resulting in a 74-faceted cut with even greater brilliance. While it has the strong brilliance and square shape characteristic of brilliant cuts, the rounded corners give it a soft and elegant impression.

ROYAL ASSCHER OVAL CUT DIAMOND RING
Royal Asscher Oval Cut
 
In 2017, father-son duo Edward Asscher, a fifth-generation owner, and Mike Asscher, a sixth-generation owner, developed the "Royal Asscher Oval Cut," adding 16 facets to the standard 58-facet oval cut—eight on the crown and eight on the pavilion—to create a 74-facet design. Because the clarity and brilliance of an oval cut are significantly affected by the overall proportions and balance of its outline, Royal Asscher introduced consistent cutting standards to oval cuts, which are often cut with irregular aspect ratios. After simulating various aspect ratios, they determined a 1:1.4 ratio to maximize light reflection and achieve ideal brilliance. This maximizes yield while achieving a beautiful appearance and consistent, beautiful brilliance.
