1.13 Ct. Blue Sapphire from Ceylon (Sri Lanka)

This oval 1.13 carat blue sapphire is a refined example of classic Ceylon color and precision cutting, measuring 7.16 by 5.70 by 3.40 millimeters. The stone is transparent and faceted in a mixed brilliant cut, a style that combines the depth of a step pavilion with the scintillation of brilliant crown facets to maximize return of light from the vivid blue body color. The mixed brilliant cut is particularly effective in oval proportions, where careful facet placement enhances both face up brilliance and the perception of size, giving this 1.13 carat gem an elegant presence on a finger or in a pendant. The dimensions indicate a balanced table and depth profile, and the excellent polish ensures the surface facets catch light crisply without haziness or soft facet junctions. For a collector or a jeweler seeking a fine center stone, these proportions and finish are engineered to deliver immediate visual impact, while preserving the integrity and natural beauty of the sapphire.

Clarity has been graded as very slightly included when evaluated at eye level, which means the stone exhibits only minor natural inclusions that do not detract from the overall transparency or visual appeal, but instead serve as identifying characteristics of a natural corundum. In practical terms, these tiny inclusions are not visible in everyday wear at normal viewing distances and they do not compromise durability. The vivid color intensity is the dominant factor in the gem’s character, and Ceylon sapphires are renowned for a lively, saturated blue that often shows a luminous medium to medium deep tone, qualities that this particular stone displays. The combination of vivid color, clean appearance to the eye, and an excellent polish elevates market desirability, because buyers who understand sapphire valuation place primary emphasis on color, followed by clarity and cut. This sapphire will set beautifully in both classic solitaire and more contemporary halo settings, where its oval silhouette can be used to create an elongating effect on the hand.

This sapphire has been heat treated, a standard and widely accepted enhancement in the trade, used to improve color uniformity and to reduce certain inclusions. Heat treatment applied by experienced craftsmen is stable and permanent, and it does not diminish the inherent value that comes from the stone’s natural origin and material quality. At The Natural Sapphire Company we fully disclose all known treatments and the gem’s provenance to ensure buyers have an accurate understanding of what they are purchasing, and we provide detailed, transparent information for clients who require documentation for insurance or appraisals. Heat treatment is part of modern lapidary practice, and when combined with the sapphire’s inherent vivid color, excellent polish, and careful cutting, the result is a durable, lively gemstone that will retain its beauty with normal wear and basic care. For long term care, gentle cleaning with warm soapy water and a soft brush is recommended, avoiding harsh chemicals and extreme temperature shocks that can strain any facet junction.

Ethical sourcing is central to the value proposition for conscious collectors, and this sapphire’s origin in Ceylon, Sri Lanka, carries a long history of artisanal mining and gem cutting expertise. At The Natural Sapphire Company we work directly with trusted partners and supply chains that emphasize transparent purchasing, fair labor practices, and respect for local communities, and we seek to support initiatives that improve traceability and environmental stewardship in mining regions. For the conscientious buyer, owning a gemstone like this means investing in a piece that is not only aesthetically superior, but also acquired with an emphasis on responsible practice and full disclosure. As a naturally occurring corundum with documented origin, known enhancement, and a combination of vivid color, very slight inclusions, and excellent cut and polish, this sapphire stands as a refined choice for an heirloom quality collection, suitable for both everyday wear and for passing on to future generations as a symbol of thoughtful, informed collecting.
