2.04 Ct. Blue Sapphire from Tanzania

One transparent 2.04 carat oval blue sapphire, measuring 9.03 x 6.71 x 3.64 mm, presents a balanced combination of weight and dimensions well suited for a variety of fine jewelry settings. The stone is fashioned with a mixed brilliant cut that combines a faceted crown and pavilion geometry to optimize both brilliance and depth. Clarity is graded very slightly included when evaluated at eye level, indicating that the gem appears clean to the naked eye while retaining natural internal characteristics that attest to its origin. Color is classified as vivid intensity, with a saturated, consistent blue distributed across the table and crown, and the surface shows an excellent polish that promotes clean facet reflections. This sapphire is unenhanced, and the material is natural, sourced from Tanzania. The Natural Sapphire Company confirms full disclosure of origin and treatment status for this gem.

Under varied lighting conditions the sapphire displays distinct but predictable optical behavior, driven by its vivid color, mixed brilliant cut, and high polish. In bright natural daylight the stone shows a pure, saturated blue, with strong facet contrast and lively scintillation as the mixed cut returns both broad flashes from the table and smaller pinpoints of light from the crown facets. Under warm incandescent light the blue takes on a deeper, velvety tone, with a subtle leaning toward a slightly purplish undertone that enhances perceived depth while maintaining luminous internal reflections. Under cool white LED or fluorescent illumination the sapphire appears more electric and vivid, with higher contrast between flashes and darker facet junctions, producing crisp sparkle and a sense of clarity. In low light or candlelight the overall brilliance is reduced, while the intense blue becomes more concentrated and rich, offering a luxurious, saturated appearance. The excellent polish and the very slightly included clarity permit efficient light transmission and attractive optical performance in all environments, while the lack of enhancement ensures these responses are inherent to the natural Tanzanian material. This gem is recommended for secure, well proportioned settings that allow the table and crown to interact with light, preserving its visual character as presented by The Natural Sapphire Company.
