Pave Green Sapphire Ring 1.62 Ct., 18K Yellow Gold

This ring centers on a beautifully transparent 1.62 carat cushion shape green sapphire, measuring 6.63 by 5.79 by 4.35 millimetres, cut with a mixed brilliant faceting scheme to maximize light return and lively scintillation. The sapphire is graded as very slightly included when evaluated at eye level, which means the stone is essentially clean to the naked eye while retaining natural internal character that enhances depth and individuality. Color saturation is intense, and the polish is excellent, together producing a rich green hue with strong internal reflection. Importantly, this sapphire is natural and untreated, with no enhancement, and its documented origin is Madagascar, a source known for producing richly coloured green and blue sapphires that appeal to collectors and connoisseurs who value provenance and natural formation. Corundum, the species to which sapphire belongs, has a refractive index around 1.76 to 1.77, and when paired with an intelligent faceting plan such as a mixed brilliant cushion, it returns light with notable brilliance and a pleasing balance of flash and fire.

The mixed brilliant cut employed in this cushion shape is specifically chosen to maximize brilliance while preserving the softer silhouette of the cushion form. The mixed brilliant design uses a faceted crown that disperses light into spectrum flashes and a deeper pavilion that controls internal reflection for optimal return to the eye. The crown pavilion relationship, refined table size, and carefully proportioned facet angles on this 6.63 by 5.79 by 4.35 millimetre stone are calibrated to enhance brightness and scintillation across a range of lighting conditions, from daylight to indoor lighting. The cushion outline with gently rounded corners allows broader facets to act as windows for colour, creating areas of concentrated tone that display the sapphire’s intense saturation without appearing dead or overly dark. Because the stone is untreated, its optical behavior is natural and consistent over time, and the excellent polish further reduces light leakage at facet junctions so that reflections remain crisp, contrasty, and lively. For the educated buyer who understands the interplay between refractive index, facet geometry, and polish quality, this sapphire represents a well executed marriage of material quality and lapidary skill.

The mounting complements and enhances the sapphire’s optical performance, set in warm 18K yellow gold with a refined twist to the band that channels light toward the centre stone. Accenting the shoulders are natural white round diamonds, including smaller stones weighing approximately 0.04 carats with clarity graded Very Slightly Included, VS1 and VS2, and colour grade F, alongside additional white round diamonds totalling approximately 0.135 carats with clarity rated VS and colour grade F to G. These diamonds are selected for their clean appearance and near colourless tone, providing crisp white contrast that elevates the green hue of the sapphire and increases perceived brilliance through contrast and additional reflective surfaces. The four prong setting allows generous light entry from the pavilion and sides, while the twisted pave shoulders introduce additional facets and reflection points that animate the ring during movement. At The Natural Sapphire Company we place emphasis on documented origin, natural condition, and lapidary quality, and this ring is presented for buyers who value traceable provenance, untreated material, and a detailed attention to optical performance. For care we recommend routine gentle cleaning with mild soap and a soft brush, and for any purchaser seeking further documentation or close inspection we can provide certification and high resolution imagery on request.
