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. Holiday Season Limited Collection選べるダイヤモンドIn this section, we select 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.

Princess Cut Diamond

In the 20th century, by Marcel Tolkowski, who was a diamond cutter and also a PhD in mathematicsTwo elements derived theoretically"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 brilliance of the diamond is maximized.
The "Round Brilliant Cut Diamond," which has become the standard for cutting today, and its evolved form, the "Princess Cut Diamond," are characterized by their strong and beautiful brilliance.

When using prong settings, 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.
