Three Stone Greenish Brown Sapphire Ring 4.07 Ct., 18K Yellow Gold

This ring centers a 4.07 carat, emerald cut, greenish brown Ceylon sapphire, precisely measured at 8.84 by 7.38 by 6.19 millimeters, and finished with an emerald step facet arrangement. The emerald cut’s broad table and series of parallel step facets produce a hall-of-mirrors effect that emphasizes color depth and internal structure rather than scintillation. With intense color saturation and an eye clean clarity grade at standard viewing distance, the sapphire presents a strong, saturated tone without obvious surface-reaching inclusions. Under magnification, however, telltale natural features native to Sri Lankan sapphires become apparent, including fine silk, minute crystal inclusions, and subtle growth zoning. Because this stone is untreated, those micro-inclusions remain intact, acting as a natural fingerprint that documents formation conditions and geological provenance. The interplay of step facets with those internal features yields a layered optical complexity, where thin silk threads diffuse light to impart a soft velvet sheen in some facets, while tiny reflective crystals create discreet pinpoints of internal sparkle, together producing a unique depth and movement that cannot be replicated in synthetic or heat-treated material.

The mounting and supporting stones are designed to complement the sapphire’s technical character. The two white half-moon natural diamonds, totaling approximately 0.30 carats and graded VS1 to VS2 in clarity with an F color grade, flank the centre and are precision cut to sit flush against the rectangular shoulders of the emerald cut. Their faceted geometry and high polish contribute contrast and brightness, framing the step cut center without competing with its color saturation. The sapphire is secured in a four-prong basket with an open gallery, crafted in 18 karat yellow gold, where the warm metal tone subtly enriches the greenish brown hue while the open pavilion and hand-finished prongs allow light to traverse the stone and interact with its internal features. The excellent polish and symmetry of both the sapphire and diamonds reflect meticulous lapidary and benchwork, and the absence of enhancement preserves the stone’s natural inclusions as integral elements of its character. At The Natural Sapphire Company this ring is presented as a study in natural complexity, where each microscopic inclusion and facet plane contributes to a singular optical signature and collectible provenance.
