Three Stone Green Sapphire Ring 3.94 Ct., 18K Rose Gold

This ring centers a transparent three point nine four carat oval green sapphire measuring ten point fifteen by eight point forty one by five point sixty four millimeters, cut in a mixed brilliant style that marries a brilliant crown with a pavilion tailored to preserve color and maximize return of light. The mixed brilliant faceting produces a controlled spread of larger crown facets and precise pavilion angles, delivering scintillation while maintaining the stone body color at light saturation, the stone showing slightly included clarity at eye level and an excellent polish that minimizes surface abrasion and enhances facet delineation. The proportions yield a depth of approximately fifty six percent, which balances brilliance against face up spread for an oval of this size, and the Montana origin contributes the classic sage green hue prized for its daylight performance. The mounting is rendered in fourteen karat rose gold, with a four prong cathedral basket that secures the pavilion and girdle while allowing the crown facets to interact freely with light. Flanking the center are natural white round diamonds set as small shoulder stones, the first grouping weighing approximately zero point one two carats total with clarity grades Very Slightly Included in the VS1 to VS2 range and color grade F, and the second grouping weighing approximately zero point one four four carats total with VS clarity and F to G color, cut and bead set along a twisted shank which adds structural reinforcement where the shoulders meet the prongs.

From a durability and daily wear perspective this piece is engineered to perform, starting with the sapphire itself which is corundum, possessing a Mohs hardness of nine and excellent resistance to scratching from most materials encountered in normal wear. Corundum exhibits no true basal cleavage, and its inherent toughness resists fracture under moderate impact, although facet junctions and thin girdle areas remain the most susceptible points if subjected to sharp blows. The chosen four prong cathedral setting protects the girdle and lifts the crown slightly to reduce edge impacts, while the pavé and bead setting of the small white diamonds secures them against rotation and loss, noting that diamonds are harder at Mohs ten but can cleave along octahedral planes if struck. Fourteen karat rose gold provides an optimal balance of ductility and wear resistance for daily rings, though periodic inspection of prongs is recommended to maintain security. For routine care The Natural Sapphire Company recommends gentle cleaning with warm soapy water and a soft brush, avoidance of hard knocks and abrasive surfaces, and an annual setting check to ensure long term integrity.
