Title:
装飾用ダイヤモンドカットジュエリー表面
Document Type and Number:
Japanese Patent JP4028489
Kind Code:
B2
Abstract:
Jewelry pieces, for example, earrings, pendants, rings and the like, made of metal such as gold or silver and the like, with special surface texturing to improve and enhance the light-reflecting characteristics of the jewelry. The surface texturing is formed by forming a series of grooves by the process of diamond-cutting the surface of the jewelry piece to divide the surface thereof into a plurality of adjacent, four-sided regions, each of which is bounded by four diamond-cut grooves and defines a mesa with at least four light-reflecting sloping sides. The mesas are further subdivided by forming a pair of diamond-cut grooves that criss-cross one another, thereby dividing the mesas in the four-sided regions into four sub-mesas, each having at least three sloping light reflecting sides. Preferably, first gemstones are set at the junctures of the four-sided mesas and second gemstones are set at the center, where the four sub-mesas meet.
