Pave Blue Sapphire Ring 4.48 Ct., 18K Yellow Gold

This ring from The Natural Sapphire Company features a GIA certified, transparent blue sapphire weighing 4.48 carats, with dimensions 10.54 millimeters by 7.85 millimeters by 6.01 millimeters and a mixed brilliant cushion shape. The stone exhibits eye clean clarity when viewed at eye level, vivid color saturation, and an excellent polish, and it has been heat treated, origin Ceylon, Sri Lanka. The gem sits in an 18 karat yellow gold mounting, accompanied by natural white round diamonds on the shoulders, with individual approximate weights of 0.072 carats, 0.06 carats, 0.09 carats, and 0.036 carats, and combined diamond weight approximately 0.258 carats. All accent diamonds are graded VS for clarity and F or G for color. The sapphire proportions result in a depth of approximately 65 percent, a balance that preserves the gem’s rich, vivid blue while supporting lively light return. The craftsmanship emphasizes secure prong work and a refined profile that showcases the sapphire from multiple viewing angles.

The mixed brilliant cushion cut used for this sapphire optimizes light performance in a way that differs from other common cuts and styles. Compared with a round brilliant, which typically maximizes overall brightness and scintillation, the cushion mixed brilliant produces broader flashes of light and deeper color saturation, a quality particularly beneficial for a vivid Ceylon sapphire that one wishes to present as intensely blue rather than washed out by excessive white light return. Against step cuts such as emerald or Asscher, which emphasize color depth and clarity but yield much less sparkle, the mixed brilliant offers a compelling middle ground, delivering both noticeable scintillation and preservation of the stone’s saturated hue. Compared with older, chunkier cushion and antique cuts, the mixed brilliant facets provide more precise facet geometry and more controlled light performance, creating lively contrast and dynamic flash without sacrificing the gem’s visual weight. The white round diamonds in F G color and VS clarity frame the center stone with bright, clean sparkle, and the warmth of 18 karat yellow gold enhances the sapphire’s vivid blue, resulting in a balanced and refined presentation.
