Pave Blue Sapphire Ring 4.18 Ct., Platinum 950

This ring centers a spectacular, C.Dunaigre certified Ceylon blue sapphire, weighing 4.18 carats and cut in a round mixed brilliant form, with precise dimensions of 8.84 by 8.63 by 6.75 millimeters. The mixed brilliant cutting style combines a brilliant facet arrangement on the crown with a complementary pavilion design engineered to maximize both scintillation and color depth, producing lively flashes of white light and saturated blue flashes as the ring moves. This particular stone carries an evaluation of very slightly included at eye level, which for an educated buyer is a favorable clarity profile because the inclusions are minimal, do not impede light return, and affirm the natural origin of the gem. The sapphire exhibits intense color saturation and an excellent polish, and importantly it has not undergone any enhancement, making the stone materially rarer and more desirable, especially for collectors and connoisseurs who place a premium on untreated Ceylon sapphires. The provenance of Sri Lanka is significant, because Ceylon sapphires are renowned for their pure, often cornflower to intense blue hues, a tonal quality that reads beautifully at this size and which the mixed brilliant cut amplifies by preserving color while delivering robust brilliance.

The setting architecture is engineered to make the sapphire visually larger and to enhance its inherent fire, clarity, and color contrast. The center stone is elevated in a secure four prong head, positioned above a meticulously crafted two tier diamond halo that frames the sapphire and creates a reflective border that intensifies perceived color saturation. The upper halo features uniformly matched round diamonds in a bead set and pave arrangement that provides a continuous rim of white sparkle directly adjacent to the sapphire, while a secondary row beneath the top halo adds depth and a shadowing effect that increases apparent size without obscuring light entry to the pavilion. The gallery is open and sculpted to permit light to pass beneath the pavilion, which enhances return and intensifies blue saturation, and the shoulders are fully pave set with fine, evenly spaced round diamonds that flow down both sides of the band, creating a seamless transition from the focal stone to the finger. The metalwork is executed in 18K white gold, which offers an optimal white field against which the F G color graded diamonds read as icy white, improving contrast and apparent color purity of the center sapphire.

The diamond complement in this piece totals approximately two carats, allocated in carefully curated groups to balance the center stone and the ring silhouette, and each diamond is natural, round shaped, clarity VS, and color graded F or G. The individual diamond parcels are weighted at about 0.45 carats, 0.60 carats, 0.27 carats, and 0.68 carats, and together they form a measured brilliance that supports rather than competes with the sapphire. For an educated buyer, these specifications matter because VS clarity assures excellent purity to the naked eye while F G color provides near colorless performance under daylight and artificial light, preserving a cool white background that accentuates the sapphire blue. The craftsmanship, visible in the precise seatings, uniform grain work, and the smooth, polished finishes on the prongs and inner shank, indicates a high level of bench work that minimizes metal visibility around each diamond, maximizing scintillation and longevity. The combination of a highly desirable untreated Ceylon sapphire, a carefully considered mixed brilliant cut, and nearly two carats of well matched diamonds set in 18K white gold results in a ring that is both visually arresting and technically refined, a piece that holds its appeal to both connoisseurs and investors.

At The Natural Sapphire Company we present this ring as an object of both aesthetic and gemological merit, because it combines a rare untreated origin stone with thoughtful design and exacting setting techniques. For buyers who focus on intrinsic value, the lack of enhancement, the certification, and the Ceylon origin are critical attributes, while the mixed brilliant cut and the open, diamond framed setting represent choices made to optimize color, light performance, and wearability. The ring is suitable for daily wear with appropriate care, and its construction in 18K white gold balances durability with the bright white visual field that amplifies the contrast between the diamonds and the blue sapphire. For those seeking a statement piece with measurable gemological virtues, this ring offers a transparent specification profile, superior craftsmanship, and the provenance and certification that informed purchasers require.
