Odd-numbered Double Fire Diamond Cutting

Description: Like glass, uncut diamonds are transparent or translucent, and they don't have the sparkling brilliance as finished diamonds. After cutting the diamond, it refracts the light and presents a sparkling visual effect. An odd-numbered double fire diamond cutting scheme, based on the odd-numbered petal face diamond cutting design. The invention applies the original odd-numbered double fire color scheme, and uses the characteristic of diamond refractive index of 2.417. Through the precise design and layout of the diamond petals, as well the exact facet shapes, positions and angles from the crown and the pavilion, combined with detailed cutting execution, light effects of diamonds such as refraction and dispersion are comparatively enhanced, which presents a clear rose shaped light performance. Because of the novelty and the uniqueness of this design , the emotional attributes are relatively enriched, as well as the collection value and the premium capacity of the diamonds are increased. Furthermore, diamond products with 11-petal surface design that shows the rose shaped light performance are more popular among marriage proposals and marriage couples.

The 4C grading system is the globally accepted standard for assessing the quality of a diamond. In the 4C system, one feature of the “Cut” is the “symmetry of the facets”. Therefore, the designers usually apply the 360° divided even numbers to design the petals of the diamond, in order to achieve the "symmetry of the facets " standard, which normally cause the same refraction effect of the diamond. The odd-numbered double fire diamond cutting scheme invented by Junwen Guo, designer of Suzhou Zigang Jewelry Co., Ltd., is based on an odd-numbered petal faceted diamond cutting plan. The invention applies the original odd-numbered double fire color scheme, and uses the characteristic of diamond refractive index of 2.417. Through the precise design and layout of the diamond petals, as well the exact facet shapes, positions and angles from the crown and the pavilion, combined with detailed cutting execution, light effects of diamonds such as refraction and dispersion are comparatively enhanced, which presents a clear rose shaped light performance. This plan combines the two elements, diamonds and roses, that represent love into one it. Mr. Michel Janssens, CEO of the Belgian HRD Antwerp diamond agency, commented that this work is a great design that truly offers the meaning of love to diamonds , and granted it “the Industrial Innovation Diamond Cut Award". The Eleven Roses diamond products applied with the 11-petal design have obtained the Very high grades in 3 diamond light performance categories, authorized by GemEx, an American company focused on diamond light performance certification. The founder of the institution, Mr. Randall Wagner, presented the product as excellent light performance in a video, and awarded the "Odd-numbered Double Fire Diamond Pioneer Certificate" for the Eleven Roses diamonds. Because of the novelty and the uniqueness of this design, the emotional attributes are relatively enriched, as well as the collection value and the premium capacity of the diamonds are increased. Furthermore, diamond products with 11-petal surface design that shows the rose shaped light performance are more popular among marriage proposals and marriage couples. For better respect and protect the nature, the plan will more practice on artificial diamonds which are less harmful to the environment. Especially the multi-faceted odd-numbered double fire design, which are suitable for large size diamonds, better applies for low-priced lab-grown diamonds. On May 7, 2021, the 265-faceted full-size diamond: Fire Queen, designed by Mr. Guo, was unveiled in the premier China International Consumer Products Expo in Hainan Province. The diamond design was granted the Guinness World Record certificate, as the most faceted diamond. The 265-faceted full-size diamond Fire Queen was the only new product release conference held by an enterprise, and was also listed by the "Hainan Daily", as one of the seven most spectacular products from the exhibition. It became widely favored by distributors and consumers.
