Antique Style Green Sapphire Ring 4.10 Ct., 18K Yellow Gold

This ring centers a transparent cushion shape green sapphire weighing 4.10 carats, with exact dimensions of 11.00 by 8.36 by 4.72 millimeters, and a mixed brilliant cut that balances table facets with pavilion brilliance. The stone exhibits vivid color saturation and an excellent polish, and it has been evaluated as very slightly included at eye level, a clarity grade that supports both transparency and visual depth. Origin is Ceylon Sri Lanka, a source long recognized for producing sapphires with lively tone and saturation, and the sapphire has received a standard heat treatment to enhance color and stability. The cushion outline and mixed brilliant faceting produce a blend of soft, rounded form with strong internal light return, allowing the green hue to read as rich and saturated in varied lighting conditions while maintaining a clean face up appearance free from dominant inclusions.

The mounting is executed in 18 karat yellow gold, and the design language favors an elevated, open setting with four prongs and a delicately engraved band. The elevated gallery and slender prongs lift the sapphire to maximize light entry to the pavilion, while the engraved shoulders and subtle openwork recall the hand crafted details found in late 19th century and early 20th century jewelry. In proportion and function the mounting is comparable to the cathedral and solitaire crowns that were favoured in Victorian era examples, where a raised profile and visible under gallery were used to emphasize a single significant stone. The engraved filigree and scrolling motifs along the band align closely with Edwardian and Belle Epoque traditions, in which fine openwork and hand engraving were employed to add visual texture and lightness to precious metal frameworks. The overall effect is a considered pairing of a modern cut sapphire with a historically informed setting, where the mounting technique echoes the finely worked mounts of classical salon jewels while remaining structurally suited to contemporary daily wear.

The combination of a 4.10 carat Ceylon green sapphire and a robust 18 karat gold mounting offers both presence and practicality, because sapphire rates nine on the Mohs scale and withstands everyday wear with proper care. The heat treatment applied to this stone is a stable enhancement that improves color uniformity without compromising structural integrity, and the very slightly included clarity grade suggests that routine ultrasonic cleaning is acceptable, though the manufacturer recommends warm soapy water and a soft brush for regular maintenance and periodic professional inspection to ensure prong security. At The Natural Sapphire Company we document origin, treatment, and measured characteristics to provide a clear provenance, and we can supply additional imagery or independent gem reports on request. The setting’s elevated profile and open gallery support light interaction and allow the stone to present strongly on the hand, while the engraved band provides visual interest from every angle, consistent with a tradition of jewellery where mount and gemstone form a single considered composition.
