Antique Style Greyish Blue Sapphire Ring 1.31 Ct., 18K White & Yellow

This ring centers on a transparent 1.31 carat round greyish blue sapphire, exhibiting dimensions of 6.33 by 6.34 by 4.35 millimeters and a mixed brilliant cut, presented without any enhancement and graded with very slightly included clarity at eye level and medium color saturation, with an excellent polish. The choice of a mixed brilliant cut optimizes both scintillation and color dispersion, while the Montana origin contributes naturally to the cool grey blue tonal character. The sapphire sits within a carefully considered head that uses white gold to surround the crown, and the surrounding diamonds are white round natural stones weighing approximately 0.426 carats in total, graded Very Slightly Included, VS1 and VS2, with an F color grade. The combination of these elements is deliberate, and the setting is designed to both protect and showcase the stone, so the intrinsic attributes of the sapphire remain the primary visual focus.

The setting enhances the sapphire color through balanced contrast and directional light management. A white gold halo and basket act as reflective surfaces that feed neutral white light into the crown facets of the sapphire, increasing apparent brightness and revealing the gem face up as a clearer, more luminous blue grey. The row of F color diamonds offers a bright white rim that frames the center stone, defining its outline and intensifying perceived saturation without overpowering it. The yellow gold band provides a warm backdrop that subtly heightens the cooler tones of the sapphire by contrast, making the greyish blue appear more distinct and refined. The mixed brilliant pavilion and crown facet arrangement work with the open gallery to invite light from below as well as from above, which supports both color depth and lively scintillation as the ring moves.

Clarity is supported by the structural choices in the mounting and by the quality of the materials. The prong work and elevated basket position the sapphire to maximize light return and to reduce the visibility of any inclusions when viewed at normal angles. The mixed brilliant cut minimizes windowing and directs light back through the crown, which helps to mask minor internal features that are consistent with a very slightly included grade at eye level. The close setting of the surrounding diamonds provides a visual buffer that draws attention to the clean face of the sapphire while the diamonds themselves, set in white gold, reflect complementary light into the center, which enhances the perception of visual purity. The excellent polish of the sapphire and the precise finish of the metalwork contribute to uninterrupted light flow and cause surface reflections to remain crisp and unobtrusive.

The ring is executed in a two tone composition of 14 karat white gold around the head and diamond halo, and 14 karat yellow gold for the band, a configuration that balances aesthetic contrast with daily wear durability. The Natural Sapphire Company designed this mounting to combine protective security with optical performance, using robust yet refined prongs and an open undergallery that supports the pavilion while permitting maximum interaction with incident light. The diamonds totaling approximately 0.426 carats provide measured brilliance and a high color and clarity standard, which complements the natural, unenhanced Montana sapphire. The result is a piece that is technically considered and visually harmonious, presenting the sapphire in a way that magnifies both its color character and its clarity in everyday viewing conditions.
