6.12 Ct. Yellow Sapphire from Ceylon (Sri Lanka)

This oval C.Dunaigre certified yellow sapphire has been executed with a precision faceting scheme that emphasizes geometric harmony and maximum light play, yielding scintillation and return that are immediately appreciable to the trained eye. The mixed brilliant cut unites a carefully proportioned brilliant style crown with a faceted pavilion geometry that channels light back through the table and crown facets, optimizing both sparkle and depth. The crown facets have been balanced against pavilion facets to control dispersion and return, producing a lively, even scintillation pattern across the 11.99 by 9.35 by 6.35 mm surface area. Symmetry is tightly controlled, and the excellent polish enhances facet junction crispness, minimizing surface diffusion and allowing each facet plane to act as a precise mirror for internal light recovery. The geometric faceting strategy reduces light leakage at the girdle and edges, preserving apparent brightness and contributing to an overall sensation of volume and brilliance in this 6.12 carat stone.

Beyond its advanced cut geometry, this sapphire presents a medium color intensity that displays vivid yellow saturation without crossing into oversteep tones, making it versatile for both classic and contemporary mounts. Clarity is graded as eye clean at standard viewing distance, indicating that no inclusions appreciable to the unaided eye interfere with light performance, a vital factor in harnessing the benefits of the mixed brilliant faceting. Origin is Ceylon Sri Lanka, a provenance known for fine crystalline structure and lively hues, and the stone is free of enhancement, a significant attribute for collectors and connoisseurs who prioritize natural state material. The stone is C.Dunaigre certified, confirming weight, dimensions, cut style, clarity observation, and no enhancement status. For setting, the oval shape and the precise facet arrangement respond exceptionally well to open bezel and four prong mounts that allow light to enter through the pavilion, and the dimensions support a strong presence on both rings and pendants while maintaining wearable proportions. The Natural Sapphire Company presents this specimen as an example of meticulous lapidary technique paired with desirable natural color and clarity, an ideal choice for clients seeking a technically sophisticated, visually engaging, untreated yellow sapphire.
