An excellent polish allows the mixed brilliant facets to perform at their best, creating a beautiful interplay of velvety blue and lively scintillation. For those who worry about color being too heavy, the oval form and the mixed brilliant cut work together to distribute color evenly while still preserving the depth that makes a 4.31 carat sapphire feel valuable and rare.
