2.80 Carat Oval Cabochon Blue Star Sapphire and Diamond Halo Ring

Natural blue star sapphire oval cabochon of approximately 2.80 carats set in a four-prong 14K white gold halo ring, encircled by 52 round brilliant diamonds totaling approximately 0.50 carats in a full diamond halo and pave shank.

Size 7, adjustable.

The 14K white gold setting features a four-prong basket that raises the oval cabochon star sapphire above a continuous oval halo of pave-set round brilliant diamonds that perfectly trace the outline of the center stone. The slim pave diamond shank flows seamlessly into the halo frame, extending the diamond coverage down the band for a polished, cohesive look. The all-white gold construction allows the deep blue of the sapphire and the bright sparkle of the diamonds to express themselves fully without visual interference from warm-toned metal.

This approximately 2.80 carat natural blue star sapphire displays a smooth, domed cabochon surface in a rich medium-deep blue, with the prized asterism phenomenon — a six-rayed star — that drifts and shimmers across the stone under direct or point light. Star sapphires have been revered for centuries across cultures as powerful talismans and collector's gems, valued for their rare optical phenomenon as much as their color. The cabochon cut is the only way to reveal the star, making this gem impossible to replicate in a faceted stone. Surrounding the sapphire, 52 round brilliant diamonds totaling approximately 0.50 carats deliver a sparkling white border that amplifies the blue and makes the star effect even more dramatic by contrast.
