这种款式的设计是受棋盘式琢型的启发,使棋盘小格的边交叉起来,设计一种十五骰子棋盘式的款式,其特征是冠部为二组交叉的小面构成(如图),切磨顺序见下表。 这种琢型也可用于椭圆形式样上,但在椭圆形中使用时,需另外增加一组腰小面,而且在其左、右端腰部需要变形。试验结果显视,这种交叉小面的组合与其它式样的亭部结合,其成品顶视效果总是非常耀目。

This style of design is inspired by the chessboard cut, so that the side of the small cross-board checkerboard, design a checkerboard style fifteen dice, which is characterized by the crown for the two groups of cross facets composition (Figure ), Cut the order shown in the table below. This cut type can also be used for the oval pattern, but when used in the oval, the need to add an additional set of waist facets, but also in its left and right waist deformation needs. Test results show that this combination of cross-facet and other styles of pavilion combination, the finished top-looking effect is always very shining.
