1.00 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This blue sapphire began its journey in the alluvial soils of Ceylon, Sri Lanka, where skilled artisanal miners recover gem material from river gravels. After extraction, the rough crystal was cataloged and subjected to an initial assessment for potential, including weight estimation and the presence of inclusions. The stone exhibited a promising hue and transparency and was selected for further evaluation. It passed through a sequence of careful cleaning and hand sorting procedures, each step documented and photographed, and then moved to a cutting studio where experienced lapidaries planned the facet layout to maximize optical performance while retaining weight. The decision to fashion the rough into an oval shape with a mixed brilliant cut was based on balancing color saturation, symmetry, and yield, and on preserving the gem character typical of Ceylon sapphires.

Through the cutting process the final proportions were established at 6.98 x 5.05 x 3.48 mm, resulting in a finished weight of 1.00 carat. The clarity was evaluated at eye level as very slightly included, indicating minor internal features that do not significantly affect transparency or light return. The color displays medium intensity, delivering a refined blue that is representative of Sri Lankan origin. The piece received a controlled heat treatment, a standard and stable enhancement for sapphires, applied to improve color uniformity and reduce the appearance of silk. Final finishing achieved an excellent polish, enhancing surface luster and facet delineation. Prior to market presentation the sapphire underwent a quality review and imaging under standardized lighting, accompanied by descriptive documentation. The Natural Sapphire Company handled the gem from evaluation to final listing, ensuring traceable provenance, accurate specification of the mixed brilliant cut, treatment disclosure, and measured dimensions. This account follows the sapphire from its point of origin to market readiness, providing exact specifications and a clear record of the processes that produced the finished 1.00 carat oval blue sapphire.
