About the Setting:
The setting is a striking architectural statement in 18K yellow gold — a bold geometric hexagonal bypass frame with clean, angular facets that surround the center sapphire on three sides, each panel fully channel-set with tapered baguette diamonds that run in perfect parallel rows from corner to corner. The open bypass design leaves the lower portion of the frame deliberately open, creating a modern asymmetric silhouette that differentiates this ring entirely from conventional halo or cluster settings. The high-polish yellow gold surfaces between the diamond channels reflect light with a warm intensity that contrasts beautifully against the icy white baguettes and the blue-to-purple color-changing sapphire at the center.
About the Stone:
The 7.18 carat GRS-certified natural color change sapphire from Sri Lanka is one of the most extraordinary and sought-after phenomena in the entire gemstone world — a single stone that displays two distinct colors depending on the light source, shifting from a rich violet-blue in daylight to a deep purple under incandescent light. Sri Lanka (Ceylon) is the world's premier source for color change sapphires, producing stones with the cleanest, most dramatic color transitions and the finest transparency of any origin. At 7.18 carats in a cushion cut that maximizes the color display across its broad faceted table, this sapphire delivers a visual experience that no single-color stone can replicate — the wearer essentially owns two different gems in one. GRS certification confirms the Sri Lanka origin and heated status, which is the universally accepted standard enhancement for sapphires and in no way diminishes the stone's extraordinary natural rarity.
