Roger Dubuis And Kaz Shirane Join Forces For Stunning Excalibur Superbia

Roger Dubuis is a brand that loves a challenge, wither it be technical or aesthetically of nature. For the new Excalibur Superbia, the brand joined forces with internationally renowned Japanese artist and architect Kaz Shirane and created a gemstone setting unlike any seen before. Six hundred diamonds and blue sapphires, with a total of 11 carats, decorate the case. However, they do not feature a baguette or brilliant-cut, but a tetrahedron cut instead. This triangular form is incredibly complex to cut and represents the diamond's basic atomic building blocks' shape.
