1.00 Ct. White Sapphire from Ceylon (Sri Lanka)

This transparent, round white sapphire presents a precise one point zero zero carat weight, with calibrated dimensions of 6.10 by 6.10 by 4.00 millimeters, and a calculated depth of approximately 65.6 percent. The gem has been fashioned in a mixed brilliant cut, combining a brilliant style crown with a modified pavilion faceting scheme to optimize both scintillation and return of white light. The crown exhibits well proportioned star and kite facets, and the pavilion demonstrates consistent facet alignment, yielding strong facet contrast and controlled light leakage. Clarity is graded eye clean at standard viewing distance, indicating no inclusions visible to the unaided eye, and the colorless color intensity affords near neutral transmission across the visible spectrum. The polish has been evaluated as excellent, with crisp facet junctions and minimal abrasion, and no enhancement has been applied to this natural Ceylon sapphire, which preserves the original corundum structure and surface finish.

This stone is sourced from Ceylon Sri Lanka, a region with a documented heritage of producing sapphires prized in both ceremonial and daily wear since antiquity. Historically, Ceylon sapphires were incorporated into royal and religious jewelry, used as central stones in bridal diadems, signet mounts, and talismanic pieces, where durable, high clarity white corundum provided both symbolic purity and practical longevity. The present round mixed brilliant white sapphire reflects that lineage of use, offering the classical proportions favored in antique solitaire and halo settings, while delivering modern lapidary precision. The Natural Sapphire Company sources and cuts material with attention to traditional aesthetics and contemporary cutting science, preserving provenance while maximizing optical performance.

For jewelry design considerations, the stone dimensions and mixed brilliant faceting make it well suited to four or six prong solitaires, low profile bezels that protect the girdle, or pavé halo mountings that amplify perceived diameter without sacrificing table brightness. Its corundum hardness of nine on the Mohs scale ensures excellent durability for everyday wear, and the absence of heat or clarity treatments means long term stability of tone and clarity.
