1.16 Ct. Blue Sapphire from Tanzania

This remarkable transparent blue sapphire weighs 1.16 carat and is cut into a classic cushion shape with dimensions 5.68 by 5.58 by 4.22 mm, offering an ideal balance between presence and versatility for both investment and bespoke jewelry applications. The mixed brilliant cut has been skillfully executed to maximize fire and scintillation while preserving weight, and the excellent polish further enhances light return across the table and crown facets. Evaluated at eye level the clarity grade is very slightly included, which means inclusions are minimal and do not detract from the gem when set, while also serving as natural fingerprints that confirm authenticity. The color reads as intense blue, a highly desirable saturation that provides depth and liveliness without appearing overly dark, and importantly this sapphire is unenhanced with no heat treatment or other alterations, a factor that significantly increases its rarity and market desirability. Origin is Tanzania, a source known for producing sapphires with vibrant cornflower to deep blue tones, and the combination of natural origin, untreated status, precise cutting, and excellent polish positions this stone as a premium specimen for connoisseurs.

For the educated buyer assembling a high end gemstone collection this sapphire represents a sound acquisition, combining verifiable natural provenance with gemological quality attributes that hold value over time. The 1.16 carat weight is particularly attractive for collectors who appreciate stones that can be set into elegant rings or retained as loose gems for pedigree portfolios, and the cushion outline remains highly sought after for its adaptable aesthetic and contemporary appeal. Very slightly included clarity at eye level preserves both transparency and integrity, while the intense color intensity ensures visual impact in any mounting, whether solitaire or halo. As with all offerings from The Natural Sapphire Company this sapphire is presented with transparent documentation and expert guidance, and we can assist with independent certification, custom design options, and secure storage or appraisal services. For collectors seeking an untreated, Tanzanian blue sapphire with superb cutting and polish, this gem is a distinguished addition that will both complement a refined collection and serve as a lasting example of natural beauty and gemological excellence.
