The Round Brilliant Cut is the most classic and popular facet in the gemstone world, and is particularly suited to high dispersion stones such as rubies. Cultivated rubies, through laboratory techniques, are able to achieve more perfect color and clarity than natural rubies, while maintaining an excellent price/performance ratio.

58 precise facets (including table, crown and pavilion facets) maximize light reflection for the ultimate fire  

- Ideal proportions (e.g. table width ratio 53%-58%, crown angle 34°-35°) to ensure the best optical effect  

- Extremely high symmetry (precisely controlled in the laboratory to avoid asymmetry, a common problem with natural stones)
