This ring centers on a transparent 0.87 carat marquise shape blue sapphire, with dimensions 8.76 x 4.53 x 2.84 mm, cut in a mixed brilliant style that emphasizes internal light return and surface brilliance. The marquise silhouette produces an elongated table and pointed terminations which guide light along the stone axis, while the mixed brilliant faceting introduces a finely tuned array of crown and pavilion facets. The sapphire is graded as very very slightly included when evaluated at eye level, with dark color saturation that gives depth to the blue, and an excellent polish that preserves crisp facet junctions and strong reflective contrast. The gem originates from Australia, and the combination of the marquise profile and meticulous finishing produces a deliberate balance between depth and surface flash.
The mixed brilliant cut is the principal mechanism by which this sapphire achieves heightened brilliance. Mixed brilliant faceting blends traditional brilliant facet patterning on the pavilion with carefully proportioned crown facets designed to optimize the escape of dispersed light into the viewer field. In this marquise the facet geometry has been arranged to reduce light leakage toward the stone girdle and the points, instead encouraging multiple internal reflections that concentrate scintillation through the length of the gem. The elongated table proportion and the ratio implied by the stated dimensions create a controlled pathway for light to travel, producing broad flashes of color interspersed with fine scintillation. Symmetry of the marquise and the exacting polish at each facet junction are essential, because they preserve the intended optical relationships and prevent diffusion of light that would otherwise mute contrast and diminish perceived brightness.
Flanking the sapphire are white half moon shaped lab grown diamonds weighing approximately 0.30 carats in total, with clarity grades recorded as Very Slightly Included, VS1 and VS2, and a color grade of F. These curved side stones are selected for their ability to mirror and amplify the pavilion and crown flash of the center stone, their rounded geometry providing a soft optical transition from the marquise profile into the shoulder. Complementing those accents are white tapered baguette shape natural diamonds totaling approximately 0.07 carats, carrying clarity grades of Very Slightly Included, VS1 and VS2, and color grade F. The linear facets of the tapered baguettes add directional sparkle that contrasts with the mixed brilliant scintillation of the sapphire and the rounded return of the half moon stones. Together they form a coordinated ensemble that reinforces central brilliance while maintaining a refined and structured silhouette.
The mounting is executed in 14K yellow gold, a metal choice that warms the sapphire hue and provides a visual frame which accentuates contrast between deep blue and colorless white diamonds. The setting geometry and open gallery are designed to allow light to enter the sapphire from multiple angles, enhancing total internal reflection and maximizing perceived brightness. The Natural Sapphire Company presents this ring with attention to both gemological specification and finishing quality, documenting the sapphire weight, measurements, cut type, clarity observation, color saturation, and country of origin, as well as the combined weights and grading of the side diamonds, and the gold specification. For collectors and connoisseurs who prioritize optical performance, the interplay of a precisely executed mixed brilliant marquise, responsibly sourced side diamonds, and a thoughtfully engineered setting combine to deliver a piece that is measured, auditable, and designed to showcase the full potential of the primary gem.
