Stone Identity & Quality
This is a 5.45 ct Ceylon Natural Unheated Blue Sapphire rough measuring 11.9 × 8.1 × 7.5 mm. The stone is sourced from Bibilegama village around mining in Sri Lanka and remains in its natural unheated condition. It is presented as facet-grade rough, suitable for professional cutting evaluation, custom faceting study, or gemstone trade interest.
Color & Visual Characteristics
The sapphire shows a vivid blue hue in rough form, with attractive color presence and useful body depth. The final face-up color after cutting will depend on orientation, cutting angles, depth retention, polish quality, and how the inclusions and internal structure are managed during preforming.
Internal & External Features
This rough sapphire shows visible inclusions together with natural rough surface features. These inclusions should be reviewed carefully before selecting the final cutting direction. The stone also has a practical rough body shape with enough depth for study, but cutting decisions should be made only after direct examination by an experienced cutter.
Cutting, Specimen, or Treatment Potential
As facet-grade blue sapphire rough, this stone can be evaluated for a custom faceted gemstone. Possible cutting directions may include oval, cushion, or another suitable design depending on the cutter’s judgment. The main points to study are orientation, inclusion position, depth, surface removal, and final yield. No finished size, clarity, or cutting result should be promised before proper technical assessment.
