4 shines, 4 perspectives

4つの輝き、4つの視点
Since the method of cutting and polishing diamonds using diamond powder was discovered in medieval Europe, various cutting techniques have been devised and developed. Xmas Limited Collection '選べるダイヤモンドWe have selected four diamond cuts that are suitable for "now," regardless of whether they are new or old. We will explore the differences in impressions created by each diamond from several perspectives.

The main element of the brilliance created by these cuts is "scintillation (mirror reflection)."The brilliance created by light reflecting off the cut surfaces applied to the surface of the diamond.The characteristic is a modest and calm impression of shine.

20th century, by Marcel Tolkowski, who was a diamond cutter and also a PhD in mathematicsTwo elements derived theoretically"The 'seven colors of dispersed light (dispersion)' and the 'strong brilliance created by reflections within the diamond (brilliance)'. When these two elements are combined with 'scintillation', the diamond's sparkle is maximized."
The "Round Brilliant Cut Diamond," which is currently the standard for cutting, and its evolved form, the "Princess Cut Diamond," are characterized by their strong and beautiful brilliance.

PERSPECTIVE04: Nails and Frame

When using prongs, it is necessary to secure each corner of the diamond with two prongs, which would hide the corners and prevent you from fully enjoying the emerald cut shape. Therefore, by adopting a "bezel setting" that surrounds the stone, we are able to maintain the integrity of the emerald cut shape.
