38.09 Ct. Blue Sapphire Crystal from Ceylon (Sri Lanka)

This listing describes one opaque blue sapphire, weight 38.09 carats, with overall dimensions 39.50 millimeters by 13.40 millimeters by 9.40 millimeters. The stone is fashioned in a rough crystal cut that preserves elements of the natural crystal habit, while receiving an excellent polish on exposed faces. Color intensity is reported as intense, and no post mining enhancements have been applied. The stated origin is Ceylon, Sri Lanka, and this specimen is presented by The Natural Sapphire Company with full measurement and treatment disclosure.

The rough crystal cut of this sapphire retains its elongated prismatic morphology, with multiple natural terminations and projections visible along the length of the piece. Surface polishing has been applied selectively to highlight facetlike planes and to provide a refined finish that contrasts with the retained natural surfaces. The body color reads as a saturated blue with consistent intensity across the majority of the stone. Internal features include natural growth zoning and localized accessory mineral inclusions that are characteristic of material formed in magmatic pegmatitic and metamorphic environments, and these features contribute to the gemological identity and visual character of the specimen. The opaque appearance is consistent with the combination of internal structure and included material, and the reported excellent polish enhances surface luster despite the overall opacity.

For design and mounting considerations, the substantial physical size and 38.09 carat weight make this sapphire particularly suitable for bespoke jewelry applications where the stone is the primary focal element. The length and depth dimensions should be accommodated in custom settings, and mounting options such as a secure bezel or a reinforced prong system will preserve the stone while displaying its elongated profile. Corundum hardness provides a high degree of wear resistance, however the presence of natural inclusions and the retained crystal terminations warrant careful setting techniques and avoidance of strong point loading. Cleaning may be performed with warm soapy water and a soft brush, and professional cleaning techniques should be discussed when any uncertainty exists, given that the stone is untreated and retains native internal and surface features.

Provenance and treatment transparency are central to the offering. The Natural Sapphire Company affirms the Ceylon origin as provided, and the no enhancement status is confirmed by our internal review, with the recommendation that an independent gemological report accompany any high value acquisition for added assurance. Ceylon sapphires are historically noted for a range of blue tones and for material that shows natural color zoning and crystal habit, and this example illustrates those characteristics in a single substantial specimen. High resolution images, measured dimensions, and treatment disclosure are provided to support evaluation and design planning.
