6.53 Ct. Blue Star Sapphire from Ceylon (Sri Lanka)

One transparent 6.53 carat oval shape blue star sapphire, presenting classic cabochon form with overall dimensions 10.18 by 9.20 by 6.41 mm, offers a balanced combination of size and proportions suitable for a variety of fine jewelry settings. The material displays medium intense blue color, with even color distribution across the girdle and dome, and an excellent polish that enhances surface luster and light return. Clarity is graded as very slightly included, evaluated at eye level, with internal characteristics that are typical for natural star sapphires and that do not detract from the gem when mounted. This specimen shows a distinct star phenomenon under direct illumination, asterism that is centered and visible across the cabochon surface, consistent with quality star sapphire material. The gem is unenhanced, no enhancement, and the documented origin is Ceylon, Sri Lanka, a source known for producing transparent blue star sapphires with appealing color and strong optical phenomena.

The Natural Sapphire Company provides this sapphire with attention to documented attributes and suitability for bespoke or design driven applications. The cabochon cut and proportions yield a pleasing dome height that supports a clear and well defined star when viewed in typical lighting conditions, and the 6.41 mm height provides durability for everyday wear in rings and pendants when properly set. The combination of medium intense color, transparency, and an excellent polish makes this stone appropriate for settings that emphasize the optical star, such as bezel or halo designs that protect the cabochon while allowing light to activate the asterism. For clients seeking a natural, untreated specimen with provenance from Ceylon Sri Lanka, this sapphire represents a straightforward and verifiable example of that material class, with a clarity grade that balances visual purity and natural character. Technical specifications and origin documentation are available upon request from The Natural Sapphire Company, and further photographic views can be provided to assist in design and setting decisions.
