About the Setting:
The 18K white gold three-stone mounting presents the classic trilogy format in its most refined and unadorned expression — a clean tapered shank rising into two three-prong round diamond shoulders that frame the elevated four-prong oval center sapphire. The white gold prong setting allows maximum light entry into both the diamonds and the sapphire, ensuring the stones perform at their optical peak from all angles. Stamped 18K and 750 on the inner shank, the ring confirms its precious metal composition and delivers the cool, bright metal tone that best complements the deep royal blue of the center sapphire.
About the Stones:
The 2.47 carat oval sapphire is GRS-certified as vivid royal blue and — critically — carries a no-heat designation, meaning it has never been subjected to heat treatment, the standard enhancement applied to the vast majority of commercial sapphires worldwide. Unheated sapphires of this color saturation and carat weight are exceptionally rare and command a significant premium over heated equivalents, as they represent the stone exactly as nature formed it. The vivid royal blue color — a deep, saturated blue with strong transparency — is among the most desirable hues in the sapphire spectrum, associated historically with the finest Ceylon and Burmese production. The two flanking round brilliant diamonds at approximately 0.30 carats each provide crisp, white brilliance that frames the blue center with elegant contrast and ensures the sapphire's color reads at its richest against a clean white background.
