This unusual hexagonally-cut diamond is a variety of the 'stellar brilliant-cut', which can be traced back to the early 17th century. This particular diamond is notable for its hexagonal culet (bottom facet), around which radiate six facets forming a star. Hexagonal-cuts came into vogue during the first half of the 20th century as a popular choice for engagement rings.

此枚不常見的六角形切割鑽石是星狀明亮式切割的一種，可追溯至17世紀早期。鑽石六個切割面以放射式圍繞中心而呈星狀形態，並以其六角形的底尖（底部刻面）為特色。在20世紀初，此類切割鑽石當時非常盛行，為訂婚戒指的首選。
